+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>

+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Intellectual Property Due Diligence
+-----------------------------------
+
+Modems and voice coding are heavily patented areas. Implementing these without
+serious consideration of IP issues would be foolish. This document describes
+the basis on which the software has been implemented.
+
+
+A check of the intellectual property information at the ITU web site shows a
+number of patent claims against the current standards implemented by spandsp.
+It is important to realise, however, that some of these patents have long
+since expired (group III fax dates back to the 1970s). Also, many are
+related to recent additions to the FAX standard, such as colour FAX handling,
+which few people ever use.
+
+The V.14 rate adaption standard seems free of patent encumberance.
+
+One patent is listed as relevant to the V.17 standard. It is a patent from
+IBM, but the ITU database does not specify its nature. I believe it is
+related to the trellis coding used, and I think it has expired. I do not
+know for sure. The techniques used in the implementation should be free of
+patent encumberance. Most of the implementation is similar to the V.29
+modem. The key addition the trellis code processing. The trellis encoding
+is trivial. The decoding uses Viterbi techniques, which are quite old.
+
+The V.21 standard dates from the 1950s. The V.23 standard is also very old.
+There is no possibility that any patents related to it are still in force.
+However, the implementation also needs to be free of patented techniques.
+The implementation only uses very mature numerical oscillator and quadrature
+correlation techniques, so there should be no patent issues.
+
+Only one patent is listed as relevant to the V.29 standard. This dates from
+the 1970s, and must have expired. The modem has been implemented using only
+very mature techniques, none of which can be less than 20 years old. There
+seem no possibility, therefore, that any patents are still in force related
+to the techniques used.
+
+Some aspect of the V.8 standard seems to have patents associated with it,
+according to the ITU patent database. I am unclear what these are. V.8 is a
+very simple standard. There seems to be nothing innovative about it.
+
+Many patents are listed as relevant to the T.30 standard. However, they all
+appear to relate to newer features, such as colour FAX, added in recent years.
+The current implementation only covers the original features from the late
+1970s, where there appear to be patent issues.
+
+The T.4 standard defines the image compression and decompression techniques
+used for group 3 FAXes. The spandsp implementation is based on code derived
+from freely available implementations of T.4. These have existed for a number
+of years without IP issues. The standard is old enough for any patents to have
+expired, anyway.
+
+V.42bis compression uses the LZW algorithm. This is the same algorithm used in
+GIF files. Unisys patented this algorithm. However, the Unisys patent has now
+expired.

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.ac' is used to create `configure' by a program
+called `autoconf'. You only need `configure.ac' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+spandsp 0.0.4 - A DSP library for telephony
+-------------------------------------------
+
+SpanDSP is a library of DSP functions for telephony, in the 8000 sample per
+second world of E1s, T1s, and higher order PCM channels. It contains low level
+functions, such as basic filters. It also contains higher level functions, such
+as cadenced supervisory tone detection, and a complete software FAX machine.
+The software has been designed to avoid intellectual property issues, using
+mature techniques where all relevant patents have expired. See the file
+DueDiligence for important information about these intellectual property issues.
+
+The library is licenced under the LGPL 2.1 licence. The test suite, and some support
+programs are licenced under the GPL 2 licence. The full text of these licences can
+be found in the file COPYING.
+
+Dependencies
+------------
+
+spandsp depends on various other packages for various tasks. Most of these
+dependencies relate to building the test suite.
+
+libtiff (and libtiff-devel on most Linux distributions) is required to
+build the spandsp library.
+
+libaudiofile (and libaudiofile-devel) is required to build the test suite
+fftw (and fftw-devel) is required to build the test suite. Version 2 or 3 of
+FFTW may be used. Spandsp adapts to the differences between them.
+
+fltk (and fltk-devel), Fl_Cartesian and Fl_Audio_Meter are required to build the
+test suite with GUI interfaces for some of the tests. The tests will build
+without these packages, but the GUI features will not be available.
+Fl_Cartesian and Fl_Audio_Meter can be downloaded from
+http://www.soft-switch.org/downloads.

+Setting up test data for the supplied suite of test programs.
+-------------------------------------------------------------
+
+Some of the tests in the test suite for this package require test data files. These test
+data files fall into four categories:
+
+ - Some data files, such as those for some of the FAX tests, are generated by programs
+ in the package.
+
+ - Some are freely distributable data files, from various sources. These are supplied
+ with the package.
+
+ - Some are test data files from a standards body. These are the copyright material of
+ the standards body, and so cannot be distributed with this package. However, most of
+ these files can currently be downloaded at no charge from the standards body's web
+ site. This file describes which files are needed, and how they may be processed to
+ produce the right files in the right places for the tests.
+
+ - The two industry standard sources of test data for DTMF decoders are Bellcore/Telcordia
+ and Mitel. Neither of these is either free, or supplied in a form directly usable
+ with the test suite. These data sources are expected by several tests, and not just
+ the DTMF decoder tests. Sad to say, you are on your own when trying to source data
+ for these tests.
+
+For the G.722 tests, obtain the file T-REC-G.722-198703-I!AppII!ZPF-E.zip from the ITU web site,
+and place it in this directory. Then run
+
+./unpack_g722_data.sh
+
+For the G.726 tests, obtain the file T-REC-G.726-199103-I!AppII!SOFT-ZST-E.zip from the ITU web
+site, and place it in this directory. Then run
+
+./unpack_g726_data.sh
+
+For the GSM 06.10 tests, obtain the file en_300961v080101p0.zip from the ETSI web site,
+and place it in this directory. If you are able to run .exe (i.e. MS DOS or Windows)
+files you can simply run
+
+./unpack_gsm0610_data.sh
+
+If you are unable to run .exe files on the machine you are using (e.e. you are not using Cygwin,
+Mingw, Wine, FreeDOS or something of that sort) you will need to find a machine which will. First,
+run
+
+./unpack_gsm0610_data.sh --no-exe
+
+This will leave 6 .EXE files in the etsitetss/gsm0610 directory. Take these to a machine which
+can run .EXE files, and execute all of them. This should result in a number of files which end
+with .COD, INP and .OUT. Copy these to the etsitests/gsm0610 directory, and run
+
+./unpack_gsm0610_data.sh --no-exe-continue
+
+The remainder of the extraction and repacking of files should then take place.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+<title>The T.38 real-time FAX over IP (FoIP) protocol</title>
+
+<para>There are two ITU recommendations which address sending FAXes over IP networks. T.37 specifies a method of encapsulating FAX images in e-mails, and transporting them to the recipient (an e-mail box, or another FAX machine) in a store-and-forward manner. T.38 specifies a protocol for transmitting a FAX across an IP network in real time. This document discusses the implementation of the T.38, real time, FAX over IP (FoIP) protocol.</para>

+<para>FAXing between two PSTN FAX machines provides the illusion of real-time communication, with confirmed delivery. This is, of course, no more than an illusion. The sender has no idea what is receiving the FAX. It might be a FAX mailbox, where the FAX might only be retrieved much later, or might never be retrieved at all. It might be a FAX machine which is out of paper, and is storing the FAX in memory. If nobody adds paper before the FAX machine is switched off, the FAX might never be printed. With increasing amounts of FAX spam, many people don't ever bother to collect FAXes from the FAX machine in their office. Still, with all these reasons why the real-time confirmed delivery nature of FAXing is an illusion, large numbers of people still insist on using direct FAXing.</para>
+
+<para>The FAX protocols - in particular T.30 - were designed for the PSTN. The PSTN is very different from a packet network like the Internet. It offers very strict timing; latency is rock steady throughout a call; and latency is seldom very high. The lack of these features in packet networks tends to spoil the quality of voice over IP, compared to voice over the PSTN. However, it can totally destroy modem data, like that used for FAX. Jitter and packet loss can cause modem reception to fail, and excessive delays can cause timers designed for a low latency environment to expire. T.38 tries to mitigate these factors, and can greatly improve the reliability of FAXing across the internet. It can also send FAXes using less bandwidth than using VoIP protocols. There are limits to what can be achieved on a congested network, though, and T.38 can never offer the reliability of a store and forward protocol, like T.37. Sadly, the average office worker's love affair with real-time FAX ensures a bright future for the T.38 protocol, even though the T.37 protocol makes far more sense.</para>
+
+<para>The T.38 protocol primarily operates between:
+<itemizedlist>
+<listitem><para>Internet-aware FAX terminals, which connect directly to an IP network.</para></listitem>
+<listitem><para>FAX gateways, which allow traditional PSTN FAX terminals to communicate via the Internet.</para></listitem>
+<listitem><para>A combination of these.</para></listitem>
+</itemizedlist>
+T.38 is the only standardised protocol which exists for real-time FoIP. Reliably transporting a FAX between PSTN FAX terminals, through an IP network, requires use of the T.38 protocol at FAX gateways. VoIP connections are not robust for modem use, including FAX modem use. Most use low bit rate codecs, which cannot convey the modem signals accurately. Even when high bit rate codecs, such as G.711, are used, VoIP connections suffer dropouts and timing adjustments, which modems cannot tolerate. In a LAN environment the dropout rate may be very low, but the timing adjustments which occur in VoIP connections still make modem operation unreliable. T.38 FAX gateways deal with the delays, timing jitter, and packet loss experienced in packet networks, and isolate the PSTN FAX terminals from these as far as possible. In addition, by sending FAXes as image data, rather than digitised audio, the required bandwidth of the IP network might be reduced. However, the redundant transmission needed to make T.38 work acceptably over an unreliable network tends to offset much of the potential bandwidth gain.</para>
+
+<para>The original T.38 specification provides for operation up to 14,400bps, using a V.17 modem. The latest version of the T.38 specification adds features for FAXing at up to 33,600bps, using a V.34 modem. However, it appears most current T.38 implementations only support operation up to 14,400bps.</para>

+<title>The basics of a T.38 entity</title>
+
+<para>The T.38 protocol may be used to build an Internet-aware FAX terminal, for direct connection to the Internet. It may also be used to build gateways. A T.38 FAX gateway might be a gateway between the PSTN and the Internet. It might just be an a ATA box acting as a gateway between a directly connected traditional FAX machine and the Internet. The T.38 protocol merely defines what passes between two T.38 entities. Creating a robust entity, able to tolerate the widest possible variation in network delays, jitter and packet loss, requires considerably more than just implementing what is contained in the T.38 spec. Also, the protocol definition is somewhat loose, resulting is considerable variability in the way the protocol is implemented. Considerable flexibility is required in a T.38 entity's design, to tolerate these variations.</para>
+
+<para>T.38 currently works over one of the following transports:
+<itemizedlist>
+<listitem><para>TCP, with TPKT message framing - the use of TPKT was originally specified in a vague way, and implementations without TPKT framing apparently exist.</para></listitem>
+<listitem><para>UDPTL - A UDP based protocol used nowhere else. This is the most common transport for T.38.</para></listitem>
+<listitem><para>RTP - Added quite late to the T.38 specification, and still not widely supported.</para></listitem>
+</itemizedlist>
+TCP is the ideal way to communicate between two entities on an IP network, which do not have real-time constraints. The entities can talk as fast as they and the medium between them permit, with full error control. Internet-aware FAX devices would, therefore, usually use TCP as the transport for T.38. Gateways have only limited control of the timing of the FAX data passing through them. They have to operate in real-time, at a rate outside their control. Gateways, therefore, usually use UDPTL. The RTP option was only added to the T.38 specification in 2004, and is not yet widely supported. Over time it may become the preferred replacement for UDPTL, since most entities handle more than just FAX, and need to implement RTP anyway.</para>
+
+<para>A TCP stream is fully corrected by the TCP protocol itself. However, in the UDPTL or RTP modes of operation, T.38 is subject to possible packet loss. A high level of missing data would defeat the protocol, so some measure of FEC (forward error correction) must be used. The UDPTL specification defines two optional forms of FEC. Both consist of adding information from previous packets to new packets. In one form this repeated data is send as a direct copy of the original. In the other it is sent as parity information, which requires encoding and decoding. The specifications for RTP include definitions of suitable FEC and redundancy protocols (RFC2198 and RFC2733). The T.38 specification says these should be used for T.38 over RTP.</para>
+
+<para>Interestingly, even the latest revision of the T.38 specification does not provide properly for security in FAX transmission. SRTP is a standard way to achieve secure multi-media communication, and can be applied to T.38 over RTP without any specific wording on the subject in the T.38 specification. UDPTL might be seen as obsolete in the long term, and not worthy of enhancements to encrypt the data. However, no secure option for T.38 over TCP is defined. TPKT could be sent over TLS/TCP. TLS also has message framing features which would allow IFP packets to be sent directly over a TLS protected connection. However, there is no specified way to do this.</para>
+
+<para>Although redundant information in future packets is an important part of a solid T.38 implementation, it is not a complete solution to problem of lost packets. Sometimes the next packet occurs after a considerable delay (e.g. when allowing time for a fast modem to train). If a "start training" message is only received through the redundant information in a following packet, it usually arrives too late to be useful (at least for a gateway). Most T.38 implementations now follow a practice of sending several exact copies of key packets - generally the ones which start or end the stages of the T.30 protocol. Typically up to 4 identical copies of these packets are sent down the wire. The may be sent in a burst, as fast as possible, or they may be spaced in time by 10ms or 20ms. IP network congestion, and the resulting packet loss, can be very bursty. If all copies are sent together, they might all be lost. Even a small amount of spreading in time may significantly increase the likelihood of at least one copy reaching its destination. The price is some delay in delivery of the message, which might be problematic. Multiple copies of these packets add little to the overall volume of data transmitted, as only a small percentage of packets fall in this "key packet" category. Some T.38 implementations follow a less effective practice of sending multiple key packets, which have separate sequence numbers and are separately bundled with redundant information for transmission. They may also be spaced in time. Although this seems a less effective strategy, a T.38 entity must expect to receive packets streams of this kind, and tolerate them.</para>
+
+<para>Between the high priority key packets, and the low priority packets for the image data (the loss of which might just cause a streak on an image, or be corrected by ECM FAXing), lies the V.21 HDLC control messages. Some T.38 implementations dynamically adjust the amount of redundant information in packets, so these control messages are repeated through several packets, but the large image data packets are repeated less, or not at all. Used with care, this dynamic redundancy strategy can nicely balance data volume and reliability.</para>
+
+<para>A T.38 terminal has a lot more flexibility in how it can deal with problem data than a T.38 gateway. The terminal has no tight timing constraints governing how it behaves with regard to received data. It can wait a considerable period for delayed packets to arrive. The gateway is a man-in-the-middle, and must live with the timing constraints that imposes. This means a T.38 gateway has a rather more difficult design than a terminal.</para>

+<title>The core elements of a T.38 implementation</title>
+
+<para>There are many differences between the behaviour of a T.38 terminal and a T.38 gateway. However, some functions are common to both types of T.38 entity, particular in the IP network interface.</para>
+
+<sect1>
+<title>The T.38 Internet Fascimile Protocol (IFP) packetiser</title>
+
+<para>The T.38 specification defines an ASN.1 schema for the messages which pass between T.38 entities. These messages are called IFP (Internet Fascimile Protocol) messages. Their format is independent of the transport used to carry them. However, there are currently two slightly different versions of the ASN.1 schema. This is due to a typo in the original version of the T.38 specification. The protocol negotiation which occurs just before T.38 communication resolves which version will be used. Although the typo was corrected several years ago, it is still very more common to find implementations which only support the original buggy version.</para>
+</sect1>
+
+<sect1>
+<title>The UDPTL, RTP, TPKT packetiser</title>
+
+<para>A second level packetiser bundles the IFP packets for transmission. This functions in different ways, depending on the type of transport in use. For the unreliable transports (UDPTL and RTP) the packetiser adds forward error correction (FEC) information to the packets. This can greatly inprove the reliability of the T.38 protocol, at the expense of higher bandwidth. The amount of error correction information added to the packets is implementation dependant.</para>
+
+<para>For UDPTL, two forms of FEC are defined. One simply repeats older T.38 packets as FEC information in the current UDPTL packet. The other generates parity packets over a series of T.38 packets, and includes that parity information in the current UDPTL packet. The type of FEC to be used is negotiated just before T.38 communication begins.</para>
+
+<para>The RTP specifications (RFC3550, RFC3551, RFC2198, RFC2733) define common redundancy and FEC formats, to be used for any payload. Where T.38 packets are carried by RTP, the standard RTP FEC mechanisms are used.</para>
+
+<para>TPKT (RFC1006, RFC2126) encapsulation works over a TCP transport. TCP provides full error correction, though retries may slow it considerably. TPKT encapsulation merely provides the ability to delineate the start and end of the IFP packets in the structureless TCP stream.</para>

+<title>The HDLC decoder</title>
+<para>If the HDLC decoder in a T.38 gateway worked in whole frames, it would introduce unacceptable latency. Instead, the HDLC decoder must work progressively through the HDLC frames, outputing its results octet by octet. The T.38 message stream does not contain HDLC preamble, though it usually contains an indication that preamble is in progress. It does not contain the CRC octets, but simply an indication of whether the CRC is good or bad. The HDLC decoder provides an indication when preamble is being received, and checks the CRC octets at the end of frames to provide the good or bad indication. The decoder makes the frames available, octet by octet, to the T.38 engine for status tracking and possible modification. Tracking and modification imposes a few octets delay, but the goal is to keep this to the minimum possible. Whether the frames are modified or unmodified, good or bad they are always passed on, to maintain the appropriate timing flow for the T.30 protocol.</para>
+
+<para>An interesting aspect of the timing flow of V.21 HDLC messages on the T.38 path relates to the size of the CRC. The usual practice for sending these frames is to send one octet in each message, with the messages spaced by the duration of one octet. They will normally be sent with the minimum possible delay. The CRC at the end of each frame is two octets long, and only an indication of good or bad is sent in the T.38 messages. It takes two octet times to know if the CRC is OK or not, typically causing the flow of T.38 messages to stutter by the duration of an octet. Since flow control within a frame is not possible when frames are replayed by a remote T.38 gateway, that gateway must allow for this inevitable stutter as it prepares to begin playout of the frame.</para>

+<title>T.30 message analysis and manipulation</title>
+<para>The T.30 message analyser in a T.38 gateway performs the following functions:
+<itemizedlist>
+<listitem><para>It passes NSS, NSF and NSC frames, but modifies their contents. A receiving FAX machine must be prevented from acting upon these messages in a manufacturer specific manner. The T.38 protocol is incapable of handling such manufacturer specific things. However, simply dropping these packets would upset the timing of the T.30 protocol. Instead, most T.38 implementations modify the country and manufacturer codes nesr the start of these messages, so the messages will be ignored by any receiver. They are typically set to 0x00, 0x55, 0xAA or 0xFF. Some implementations set them to the country and manufacturer code of the T.38 implementor. As long as they are set to something the receiver will not recognise, problems are avoided. To avoid removing useful information, the original country and manufacturer code bytes might be reinserted in a different part of the modified NSF message, provided space permits.</para></listitem>
+<listitem><para>It tracks the contents of the DCS messages. During flow control of non-ECM data, the minimum row length must be preserved, so the current minimum must be found from the DCS messages. Similarly, the current encoding must be known to apply non-ECM flow control correctly. ECM data must be flow controlled in a completely different way than non-ECM data, so ECM mode information must be found from the DCS messages.</para></listitem>
+<listitem><para>It may optionally modify the minimum row length in the DIS messages. Because flow control will be applied to non-ECM data, it can make sense to tell the sending FAX machine it has no need to impose a minimum row length, and let the emitting T.38 entity impose the minimum as part of its flow control operation.</para></listitem>
+<listitem><para>It passes on the stripped and modified HDLC frames, with the minimum possible delay. This implies that is must analyse and modify the messages octet by octet.</para></listitem>

+
+<sect1>
+<title>The HDLC rate adapting encoder</title>
+<para>The HDLC data rate adapting encoder accepts a T.30 message stream as input. The V.21 HDLC messages generally arriving byte by byte, in separate T.38 messages. ECM HDLC messages usually arrive in larger chunks, but they are still generally fragmented. The rate adapter dynamically buffers the T.30 data, generates preamble, and adjusts its length if the incoming message data is falling behind. It may insert additional flag octets between frames, as a flow control mechanism. However, the HDLC protocol is synchronous, so the adapter cannot perform any flow control within a frame. It must, therefore, buffer enough octets of a frame to provide reasonable jitter tolerance, before it emits the first octet of that frame. If the arriving messages fall too far behind mid-frame, there will be corruption of the outgoing stream. In the case of ECM image data frames, the frames are fast enough, that buffering whole frames is quite proactical within the T.30 timing constraints. This ensures mid-frame underflow can never occur.</para>
+</sect1>
+
+<sect1>
+<title>TCF (training confirmation) and non-ECM image data rate adaption</title>
+<para>Non-ECM image data rate adaption deals with exchanging TCF data, and non-ECM image data using T.4 1-D or 2-D compression. Non-ECM image data is typically padded with zero bits at the end of each pixel row. This is used to avoid rows arriving at the receiving FAX machine faster than the mechanical paper handling can process them. It is also used by sending FAX machines for flow control, when their paper handling falls behind. The minimum duration of a row is negotiated between the FAX machines, before image transfer commences.</para>
+
+<para>TCF data is a continuous stream of zero bits. It may, optionally, be preceeded by a continuous block of one bits. So, when transferring TCF data between the T.38 entities, flow control is simply a matter of repeating the last received bit when the late arrival of TCF data packets causes underflow at an emitting gateway.</para>
+
+<para>T.38 entities may negotiate to generate and check TCF data locally, and not exchange it. Generally, this is only used when TCP/TPKT is used as the transport for the T.38 messages. A TCF checker and a TCF generator are needed by a T.38 gateway supporting this option.</para>
+
+<para>Some T.38 entities are capable of negotiating the removal of end of row padding bits in the data passing between the T.38 entities. This may reduce the amount of data significantly, for some types of image. If negotiated, most or all surplus zero bits are stripped from the image bit stream, at the sending T.38 entity. If a T.38 gateway is receiving such stripped data, it may need to reimpose a minimum row time, by inserting zeros, as part of its non-ECM rate adaption process. By checking the contents of the DCS messages, it can determine what this minimum should be.</para>
+
+<para>Only two types of image compression are used for non-ECM transmission - T.4 1-D and 2-D. The end of line (EOL) marker for both these is 11 zero bits, followed by a one bit. In 2-D mode, an additional one or zero bit follows, which defines the mode of the next row. It turns out that the maximum number of valid consecutive zeros which could preceed the 11 zeros of an EOL is 3. In a valid image there are no longer runs of zeros than at an EOL, and the maximum there is 14. Therefore, if the padding stripper reduces all runs of zeros longer than 14 to just 14, it will strip most of the padding with very simple logic. Simple logic is a good thing in this case. It not only avoids the need to fully analyse the image data, it also minimises problems when there are bit errors in the image data stream.</para>
+
+<para>For image data sent without error correction (T.4 1-D or 2-D) there may be underflow at the outgoing gateway, if image data packets arrive too late. To deal with slow mechanical paper handling in FAX machines, the T.30 specification includes an end of pixel row padding scheme for non-error corrected image data. The receiving machine may request a minimum row duration. The sending machine is required to impose that minimum, but can arbitrarily make it much longer to meet its own paper handling needs, sending padding bits as appropriate. This mechanism provides a robust basis for flow control in a T.38 gateway. If the outgoing gateway only starts sending a pixel row when it has the entire row in its buffer, it can safely idle, sending padding bits, at any row end it needs to. Only the 6 EOL markers, which terminate an image, must be protected from this kind of flow control. Those markers are defined as being consecutive, with no zero bit padding separating them.</para>
+
+<para>When ECM is used (usually with T.6 image data) the image is packetised in HDLC frames. In this case rate adaption is handled in a similar manner to the V.21 HDLC packets.</para>

+The file dither1d.tif is a whole page of dense checkerboard pattern, which does not compress, and produces a kind of torture test page. It is about 2M bytes. 100page.tif is exactly what it says - a file with 100 pages of FAX images. The content of the pages does not seem to be specified by Commetrex. The ITU T.30 test images, repeated sufficiently, seems a good basis for this test. ccitt2p.tif appears to be page 2 of the ITU test images. The tests are heavily biased towards non-ECM operation with MR coding. No other coding appears to be used, and only 2 tests use error corrected (ECM) FAXing.

+<para> The T.38 specification leaves a number of grey areas, and many things can be implemented in several ways. It might, therefore, be expected that interoperability will not always run smoothly.

+<title>Non-ECM data ending immediately after the six EOLs denoting the end of a page causes corruption</title>
+<para>From the T.38 specification, a T.38 entity sending non-ECM image data should be able to end the image data, with <emphasis>t4-non-ecm-sig-end</emphasis>, at the last bit of the six consecutive EOLs which denote the end of a page. However, this offers poor compatibility with some implementations of T.38. They will drop their carrier signal prematurely, and the last few rows of the image will be corrupted at the receiver. This can happen regardless of whether the <emphasis>t4-non-ecm-sig-end</emphasis> is followed by a <emphasis>no-signal</emphasis> message, and regardless of the timing of that <emphasis>no-signal</emphasis> message. Padding with zero bytes for 40ms or more after the six EOLs seems to prevent this, and results in an image which exactly matches the one at the source.</para>

+<para>The TCF data should always be sent as non-ECM image data, whether the images which follow it are sent as non-ECM or ECM data. However, some broken implementations of T.38 (e.g. Mediatrix) may send an <emphasis>hdlc-sig-end</emphasis> message to terminate the TCF data. To be as tolerant as possible, it is probably wise to accept <emphasis>hdlc-sig-end</emphasis> or <emphasis>t4-non-ecm-sig-end</emphasis>, regardless of which kind of data it is really terminating.</para>

+<title>Expect some very poor timing decisions in various designs.</title>
+<para>The preamble for V.21 HDLC data is specified as being 1s ±15%. This should mean 850ms of preamble is within spec, and many modern FAX machines only send that much. A number of T.38 implementations choke on this. They require at least 1s between the <emphasis>v21-preamble</emphasis> message and the first HDLC data, for reliable operation. This is very poor design. Even if there is 1s between these events at the source, jitter on the network can make them arrive less than 1s apart. It appears the best a tolerant implementation can really do is impose a 1s minimum between sending these T.38 messages, and accept that things might still go wrong when there is some jitter.</para>

+<para>There is similar intolerance with the timing of the start of training messages for the fast image data modems. Most implementations do not impose a minimum which is above that permitted by the T.30 specification. Some do, however, make no allowance for network jitter reducing the interval at the receiver. You should expect the far end to be using TEP, when sizing the required delay between the start of training, and the first data. Also, for ECM data, make sure the delay allows for the specified minimum 200ms of preamble.</para>
+</sect1>
+
+<sect1>
+<title>Which kinds of error correction to use.</title>
+<para>T.38 defines two kinds of error correction for UDPTL streams. One inserts redundant copies of older IFP packets in each UDPTL packet. The other uses a more complex parity FEC scheme, based on XOR'ed data inserted in each UDPTL packet. Although each UDPTL packet identifies the type of error correction it contains, the original T.38 spec. did not offer any form of negotiation about the type to be used. The SIP and MGCP SDP for T.38 now includes preferred error correction type information, so some measure of negotiation is possible before the flow of UDPTL packets begins.</para>
+
+<para>It appears all T.38 implementations are happy to receive packets with redundant secondary content. However, it seems not all implementations will actually recover anything when there are missing UDPTL packets. It appears not all T.38 implementations are happy to receive packets with parity FEC data. Unless the SDP data from the far end explicitly says they support the parity FEC scheme, it is better to send only redundant information. A good implementation should be prepared to accept either kind of data, even intermixed, regardless of anything in the SDP negotiation. In the real world, whatever you ask for in your SDP data, you will probably receive secondary IFP packet redundancy from the far end. It is the only thing most implementations support, and with real world packet loss it may perform just as well as the more complex parity FEC scheme.</para>
+
+<para>When the first few UDPTL packets are sent, there will be no historical information to send as redundant secondary IFP packets, or parity FEC data. When using the redundant secondary packet scheme this is handled transparently. Each UDPTL packet says the number of redundant secondary IFP packets it contains. This can simply be set to zero for the first UDPTL packet, one for the second, up to the amount of redundancy which has been configured. All implementations seem to work in this way. When parity FEC is being used, the startup arrangement is less clear. While some implementations simply insert zeros for the non-existant packets before the start, others send a few packets with redundant secondary IFP packets, until they are able to insert the required amount of FEC data. Dealing with intermixed types of error correction makes a receiving implementation of UDPTL messier and slower, but is necessary for compatibility.</para>
+</sect1>
+
+<sect1>
+<title>What really ends the data?</title>
+<para>It should be correct to send some image data, and end with the image data signal end message. However, some T.38 implementations misbehave when this is all that is sent. Immediately following the signal end message with a <emphasis>no-signal</emphasis> indicator message seems to greatly improve compatibility with some T.38 implementations.</para>
+
+<para>T.38 defines <emphasis>hdlc-fcs-OK</emphasis>, <emphasis>hdlc-fcs-OK-sig-end</emphasis>, <emphasis>hdlc-sig-end</emphasis>, and <emphasis>no-signal</emphasis> messages. Always end periods of HDLC transmission with either a <emphasis>hdlc-fcs-OK</emphasis>, <emphasis>hdlc-sig-end</emphasis>, <emphasis>no-signal</emphasis> sequence or a <emphasis>hdlc-fcs-OK-sig-end</emphasis>, <emphasis>no-signal</emphasis> sequence. Do not send <emphasis>hdlc-sig-end</emphasis> after <emphasis>hdlc-fcs-OK-sig-end</emphasis>. A number of T.38 implementations choke on this sequence, even though it looks fairly harmless.</para>
+
+</sect1>
+
+<sect1>
+<title>Normal use versus testing</title>
+<para>The design of some T.38 implementations precludes some reasonable tests from succeeding, due to design features which may have been implemented for sane reasons. This means each test failure needs to be investigated in detail, to see if it represents something genuinely bad in an implementation of T.38. For example, the 2M byte torture test page in the Commetrex test suite will not successfully pass through some T.38 implementations, because of a timeout they impose. For example, some ATAs based on Audiocodes silicon have been seen to stop any continuous period of modem transmission after about 90s. This appears to be a backstop timeout, to prevent troublesome implementations jamming the gateway. Legitimate pages just don't take that long, and the timeout is reasonable. However, the 2M byte test page takes up to 20 minutes to transmit, and will always fail on these boxes.</para>

+The ITU G.1050 specification defines a model of an IP network, appropriate
+for the testing of how streaming media woud behave across the internet. The
+model is based on a path having 5 segments:
+ - a local LAN (wired or wireless)
+ - an access link to the internet
+ - an internet of arbitrary complexity
+ - an access link from the internet
+ - a distant LAN (wired or wireless)
+The impairments typical of these segments at various service levels are modelled.
+8 standard service level behaviours are defined, covering lightly loaded to heavily
+congested levels. 133 standard sets of link speeds are defined, covering typical
+wired and wireless LAN, broadband access link, and backbone characteristics.
+
+The G.1050 model is suitable for testing the behaviour of RTP, UDPTL and other streaming
+protocols for packet loss and jitter behaviour.

+SpanDSP is a library of DSP functions for telephony, in the 8000
+sample per second world of E1s, T1s, and higher order PCM channels. It
+contains low level functions, such as basic filters. It also contains
+higher level functions, such as cadenced supervisory tone detection,
+and a complete software FAX machine. The software has been designed to
+avoid intellectual property issues, using mature techniques where all
+relevant patents have expired. See the file DueDiligence for important

+ - It tolerates nasty phones that give a very wobbly start to a digit.
+ - VoIP can give sample slips. The phase jumps that produces will cause
+ the block it is in to give no detection. This logic will ride over a
+ single missed block, and not falsely declare a second digit. If the
+ hiccup happens in the wrong place on a minimum length digit, however
+ we would still fail to detect that digit. Could anything be done to
+ deal with that? Packet loss is clearly a no-go zone.

+/* TODO:
+ Finish the echo suppressor option, however nasty suppression may be.
+ Add an option to reintroduce side tone at -24dB under appropriate conditions.
+ Improve double talk detector (iterative!)
+*/
+
+/* We need to differentiate between transmitted energy which will train the echo
+ canceller well (voice, white noise, and other broadband sources) and energy
+ which will train it badly (supervisory tones, DTMF, whistles, and other
+ narrowband sources). There are many ways this might be done. This canceller uses
+ a method based on the autocorrelation qualities of the transmitted signal. A rather
+ peaky autocorrelation function is a clear sign of a narrowband signal. We only need
+ perform the autocorrelation at well spaced intervals, so the compute load is not too
+ great. Multiple successive autocorrelation functions with a similar peaky shape are a
+ clear indication of a stationary narrowband signal. Using TKEO, it should be possible to
+ greatly reduce the compute requirement for narrowband detection. */
+
+/* The FIR taps must be adapted as 32 bit values, to get the necessary finesse
+ in the adaption process. However, they are applied as 16 bit values (bits 30-15
+ of the 32 bit values) in the FIR. For the working 16 bit values, we need 4 sets.
+
+ 3 of the 16 bit sets are used on a rotating basis. Normally the canceller steps
+ round these 3 sets at regular intervals. Any time we detect double talk, we can go
+ back to the set from two steps ago with reasonable assurance it is a well adapted
+ set. We cannot just go back one step, as we may have rotated the sets just before
+ double talk or tone was detected, and that set may already be somewhat corrupted.
+
+ When narrowband energy is detected we need to continue adapting to it, to echo
+ cancel it. However, the adaption will almost certainly be going astray. Broadband
+ (or even complex sequences of narrowband) energy will normally lead to a well
+ trained cancellor, with taps matching the impulse response of the channel.
+ For stationary narrowband energy, there is usually has an infinite number of
+ alternative tap sets which will cancel it well. A previously well trained set of
+ taps will tend to drift amongst the alternatives. When broadband energy resumes, the
+ taps may be a total mismatch for the signal, and could even amplify rather than
+ attenuate the echo. The solution is to use a fourth set of 16 bit taps. When we first
+ detect the narrowband energy we save the oldest of the group of three sets, but do
+ not change back to an older set. We let the canceller cancel, and it adaption drift
+ while the narrowband energy is present. When we detect the narrowband energy has ceased,
+ we switch to using the fourth set of taps which was saved.
+
+ When we revert to an older set of taps, we must replace both the 16 bit and 32 bit
+ working tap sets. The saved 16 bit values are good enough to also be used as a replacement
+ for the 32 bit values. We loose the fractions, but they should soon settle down in a
+ reasonable way. */

+ frame (160 samples of signal d[0..159]). These parts produce at
+ the output of the coder:
+
+ Procedure 4.2.11 to 4.2.18 are to be executed four times per

+ 40 samples. These parts produce at the output of the coder.

+ DVI4 uses an adaptive delta pulse code modulation (ADPCM) encoding
+ scheme that was specified by the Interactive Multimedia Association
+ (IMA) as the "IMA ADPCM wave type". However, the encoding defined
+ here as DVI4 differs in three respects from the IMA specification:
+
+ o The RTP DVI4 header contains the predicted value rather than the
+ first sample value contained the IMA ADPCM block header.
+
+ o IMA ADPCM blocks contain an odd number of samples, since the first
+ sample of a block is contained just in the header (uncompressed),
+ followed by an even number of compressed samples. DVI4 has an
+ even number of compressed samples only, using the `predict' word
+ from the header to decode the first sample.
+
+ o For DVI4, the 4-bit samples are packed with the first sample in
+ the four most significant bits and the second sample in the four
+ least significant bits. In the IMA ADPCM codec, the samples are
+ packed in the opposite order.
+
+ Each packet contains a single DVI block. This profile only defines
+ the 4-bit-per-sample version, while IMA also specified a 3-bit-per-
+ sample encoding.
+
+ The "header" word for each channel has the following structure:
+
+ int16 predict; // predicted value of first sample
+ // from the previous block (L16 format)
+ u_int8 index; // current index into stepsize table
+ u_int8 reserved; // set to zero by sender, ignored by receiver
+
+ Each octet following the header contains two 4-bit samples, thus the
+ number of samples per packet MUST be even because there is no means
+ to indicate a partially filled last octet.

+\section adsi_page_sec_1 What does it do?
+Although ADSI has a specific meaning in some places, the term is used here to indicate
+any form of Analogue Display Service Interface, which includes caller ID, SMS, and others.
+
+The ADSI module provides for the transmission and reception of ADSI messages
+in various formats. Currently, the supported formats are:
+
+ - Bellcore/Telcordia GR-30 CORE CLASS (Custom Local Area Signaling Services) standard
+ (North America, Australia, China, Taiwan, and Hong Kong).
+
+ - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) FSK standard
+ (France, Germany, Norway, Italy, Spain, South Africa, Turkey, and the UK).
+
+ - ETSI Caller-ID support for the UK, British Telecom SIN227 and SIN242.
+
+ - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
+ variant 1 (Belgium, Brazil, Denmark, Finland, Iceland, India, Netherlands, Saudi Arabia,
+ Sweden and Uruguay).
+
+ - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
+ variant 2 (Denmark and Holland).
+
+ - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
+ variant 3.
+
+ - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
+ variant 4. (Taiwan and Kuwait).
+
+ - ETSI Caller-ID support in UK (British Telecom), British Telecomm SIN227, SIN242.
+
+ - Nippon Telegraph & Telephone Corporation JCLIP (Japanese Calling Line Identity
+ Presentation) standard.
+
+ - Telecommunications Authority of Singapore ACLIP (Analog Calling Line Identity
+ Presentation) standard.
+
+ - TDD (Telecommunications Device for the Deaf).
+
+\section adsi_page_sec_2 How does it work?
+
+\section adsi_page_sec_2a The Bellcore CLASS specification
+Most FSK based CLI formats are similar to the US CLASS one, which is as follows:
+
+The alert tone for CLI during a call is at least 100ms of silence, then
+2130Hz + 2750Hz for 88ms to 110ms. When CLI is presented at ringing time,
+this tone is not sent. In the US, CLI is usually sent between the first
+two rings. This silence period is long in the US, so the message fits easily.
+In other places, where the standard ring tone has much smaller silences,
+a line voltage reversal is used to wake up a power saving receiver, then the
+message is sent, then the phone begins to ring.
+
+The message is sent using a Bell 202 FSK modem. The data rate is 1200 bits
+per second. The message protocol uses 8-bit data words (bytes), each bounded
+by a start bit and a stop bit.
+
+Channel Carrier Message Message Data Checksum
+Seizure Signal Type Length Word(s) Word
+Signal Word Word
+
+\section adsi_page_sec_2a1 CHANNEL SEIZURE SIGNAL
+The channel seizure is 30 continuous bytes of 55h (01010101), including
+the start and stop bits (i.e. 300 bits of alternations in total).
+This provides a detectable alternating function to the CPE (i.e. the
+modem data pump).
+
+\section adsi_page_sec_2a2 CARRIER SIGNAL
+The carrier signal consists of 180 bits of 1s. This may be reduced to 80
+bits of 1s for caller ID on call waiting.
+
+\section adsi_page_sec_2a3 MESSAGE TYPE WORD
+Various message types are defined. The commonest ones for the US CLASS
+standard are:
+
+ - Type 0x04 (SDMF) - single data message. Simple caller ID (CND)
+ - Type 0x80 (MDMF) - multiple data message. A more flexible caller ID,
+ with extra information.
+
+Other messages support message waiting, for voice mail, and other display features.
+
+\section adsi_page_sec_2a4 MESSAGE LENGTH WORD
+The message length word specifies the total number of data words
+to follow.
+
+\section adsi_page_sec_2a5 DATA WORDS
+The data words contain the actual message.
+
+\section adsi_page_sec_2a6 CHECKSUM WORD
+The Checksum Word contains the twos complement of the modulo 256
+sum of the other words in the data message (i.e., message type,
+message length, and data words). The receiving equipment may
+calculate the modulo 256 sum of the received words and add this
+sum to the received checksum word. A result of zero generally
+indicates that the message was correctly received. Message
+retransmission is not supported. The sumcheck word should be followed
+by a minimum of two stop bits.
+
+\section adsi_page_sec_2b The ETSI CLIP specification
+The ETSI CLIP specification uses similar messages to the Bellcore specification.
+They are not, however, identical. First, ETSI use the V.23 modem standard, rather
+than Bell 202. Second, different fields, and different message types are available.
+
+The wake up indication generally differs from the Bellcore specification, to
+accomodate differences in European ring cadences.
+
+\section adsi_page_sec_2c The ETSI caller ID by DTMF specification
+CLI by DTMF is usually sent in a very simple way. The exchange does not give
+any prior warning (no reversal, or ring) to wake up the receiver. It just
+sends a string of DTMF digits. Around the world several variants of this
+basic scheme are used.
+
+One variant of the digit string is used in Belgium, Brazil, Denmark, Finland, Iceland,
+India, Netherlands, Saudi Arabia, Sweden and Uruguay:
+
+ - A<caller's phone number>D<redirected number>B<special information>C
+
+Each of these fields may be omitted. The following special information codes are defined
+
+ - "00" indicates the calling party number is not available.
+ - "10" indicates that the presentation of the calling party number is restricted.
+
+A second variant of the digit string is one of the following:
+
+ - A<caller's phone number>#
+ - D1# Number not available because the caller has restricted it.
+ - D2# Number not available because the call is international.
+ - D3# Number not available due to technical reasons.
+
+A third variant of the digit string is used in Taiwan and Kuwait:
+
+ - D<caller's phone number>C
+
+A forth variant of the digit string is used in Denmark and Holland:
+
+ - <caller's phone number>#
+
+There is no distinctive start marker in this format.
+
+\section adsi_page_sec_2d The Japanese specification from NTT
+
+The Japanese caller ID specification is considerably different from any of the others. It
+uses V.23 modem signals, but the message structure is uniqeue. Also, the message is delivered
+while off hook. This results in a sequence
+
+ - The phone line rings
+ - CPE answers and waits for the caller ID message
+ - CPE hangs up on receipt of the caller ID message
+ - The phone line rings a second time
+ - The CPE answers a second time, connecting the called party with the caller.

+\section bert_page_sec_1 What does it do?
+The Bit Error Rate tester generates a pseudo random bit stream. It also accepts such
+a pattern, synchronises to it, and checks the bit error rate in this stream.
+
+\section bert_page_sec_2 How does it work?
+The Bit Error Rate tester generates a bit stream, with a repeating 2047 bit pseudo
+random pattern, using an 11 stage polynomial generator. It also accepts such a pattern,
+synchronises to it, and checks the bit error rate in this stream. If the error rate is
+excessive the tester assumes synchronisation has been lost, and it attempts to
+resynchronise with the stream.
+
+The bit error rate is continuously assessed against decadic ranges -
+ > 1 in 10^2
+ > 1 in 10^3
+ > 1 in 10^4
+ > 1 in 10^5
+ > 1 in 10^6
+ > 1 in 10^7
+ < 1 in 10^7
+To ensure fairly smooth results from this assessment, each decadic level is assessed
+over 10/error rate bits. That is, to assess if the signal's BER is above or below 1 in 10^5
+the software looks over 10*10^5 => 10^6 bits.

+
+\section dc_restore_page_sec_1 What does it do?
+
+Telecoms signals often contain considerable DC, but DC upsets a lot of signal
+processing functions. Placing a zero DC restorer at the front of the processing
+chain can often simplify the downstream processing.
+
+\section dc_restore_page_sec_2 How does it work?
+
+The DC restorer uses a leaky integrator to provide a long-ish term estimate of
+the DC bias in the signal. A 32 bit estimate is used for the 16 bit audio, so
+the noise introduced by the estimation can be keep in the lower bits, and the 16
+bit DC value, which is subtracted from the signal, is fairly clean. The
+following code fragment shows the algorithm used. dc_bias is a 32 bit integer,
+while the sample and the resulting clean_sample are 16 bit integers.
+
+ dc_bias += ((((int32_t) sample << 15) - dc_bias) >> 14);

+\section dtmf_rx_page_sec_1 What does it do?
+The DTMF receiver detects the standard DTMF digits. It is compliant with
+ITU-T Q.23, ITU-T Q.24, and the local DTMF specifications of most administrations.
+Its passes the test suites. It also scores *very* well on the standard
+talk-off tests.
+
+The current design uses floating point extensively. It is not tolerant of DC.
+It is expected that a DC restore stage will be placed before the DTMF detector.
+Unless the dial tone filter is switched on, the detector has poor tolerance
+of dial tone. Whether this matter depends on your application. If you are using
+the detector in an IVR application you will need proper echo cancellation to
+get good performance in the presence of speech prompts, so dial tone will not
+exist. If you do need good dial tone tolerance, a dial tone filter can be
+enabled in the detector.
+
+The DTMF receiver's design assumes the channel is free of any DC component.
+
+\section dtmf_rx_page_sec_2 How does it work?
+Like most other DSP based DTMF detector's, this one uses the Goertzel algorithm
+to look for the DTMF tones. What makes each detector design different is just how
+that algorithm is used.
+
+Basic DTMF specs:
+ - Minimum tone on = 40ms
+ - Minimum tone off = 50ms
+ - Maximum digit rate = 10 per second
+ - Normal twist <= 8dB accepted
+ - Reverse twist <= 4dB accepted
+ - S/N >= 15dB will detect OK
+ - Attenuation <= 26dB will detect OK
+ - Frequency tolerance +- 1.5% will detect, +-3.5% will reject

+/*! \page echo_can_page Line echo cancellation for voice
+
+\section echo_can_page_sec_1 What does it do?
+This module aims to provide G.168-2002 compliant echo cancellation, to remove
+electrical echoes (e.g. from 2-4 wire hybrids) from voice calls.
+
+\section echo_can_page_sec_2 How does it work?
+The heart of the echo cancellor is FIR filter. This is adapted to match the echo
+impulse response of the telephone line. It must be long enough to adequately cover
+the duration of that impulse response. The signal transmitted to the telephone line
+is passed through the FIR filter. Once the FIR is properly adapted, the resulting
+output is an estimate of the echo signal received from the line. This is subtracted
+from the received signal. The result is an estimate of the signal which originated
+at the far end of the line, free from echos of our own transmitted signal.
+
+The least mean squares (LMS) algorithm is attributed to Widrow and Hoff, and was
+introduced in 1960. It is the commonest form of filter adaption used in things
+like modem line equalisers and line echo cancellers. There it works very well.
+However, it only works well for signals of constant amplitude. It works very poorly
+for things like speech echo cancellation, where the signal level varies widely.
+This is quite easy to fix. If the signal level is normalised - similar to applying
+AGC - LMS can work as well for a signal of varying amplitude as it does for a modem
+signal. This normalised least mean squares (NLMS) algorithm is the commonest one used
+for speech echo cancellation. Many other algorithms exist - e.g. RLS (essentially
+the same as Kalman filtering), FAP, etc. Some perform significantly better than NLMS.
+However, factors such as computational complexity and patents favour the use of NLMS.
+
+A simple refinement to NLMS can improve its performance with speech. NLMS tends
+to adapt best to the strongest parts of a signal. If the signal is white noise,
+the NLMS algorithm works very well. However, speech has more low frequency than
+high frequency content. Pre-whitening (i.e. filtering the signal to flatten
+its spectrum) the echo signal improves the adapt rate for speech, and ensures the
+final residual signal is not heavily biased towards high frequencies. A very low
+complexity filter is adequate for this, so pre-whitening adds little to the
+compute requirements of the echo canceller.
+
+An FIR filter adapted using pre-whitened NLMS performs well, provided certain
+conditions are met:
+
+ - The transmitted signal has poor self-correlation.
+ - There is no signal being generated within the environment being cancelled.
+
+The difficulty is that neither of these can be guaranteed.
+
+If the adaption is performed while transmitting noise (or something fairly noise
+like, such as voice) the adaption works very well. If the adaption is performed
+while transmitting something highly correlative (typically narrow band energy
+such as signalling tones or DTMF), the adaption can go seriously wrong. The reason
+is there is only one solution for the adaption on a near random signal - the impulse
+response of the line. For a repetitive signal, there are any number of solutions
+which converge the adaption, and nothing guides the adaption to choose the generalised
+one. Allowing an untrained canceller to converge on this kind of narrowband
+energy probably a good thing, since at least it cancels the tones. Allowing a well
+converged canceller to continue converging on such energy is just a way to ruin
+its generalised adaption. A narrowband detector is needed, so adapation can be
+suspended at appropriate times.
+
+The adaption process is based on trying to eliminate the received signal. When
+there is any signal from within the environment being cancelled it may upset the
+adaption process. Similarly, if the signal we are transmitting is small, noise
+may dominate and disturb the adaption process. If we can ensure that the
+adaption is only performed when we are transmitting a significant signal level,
+and the environment is not, things will be OK. Clearly, it is easy to tell when
+we are sending a significant signal. Telling, if the environment is generating a
+significant signal, and doing it with sufficient speed that the adaption will
+not have diverged too much more we stop it, is a little harder.
+
+The key problem in detecting when the environment is sourcing significant energy
+is that we must do this very quickly. Given a reasonably long sample of the
+received signal, there are a number of strategies which may be used to assess
+whether that signal contains a strong far end component. However, by the time
+that assessment is complete the far end signal will have already caused major
+mis-convergence in the adaption process. An assessment algorithm is needed which
+produces a fairly accurate result from a very short burst of far end energy.
+
+\section echo_can_page_sec_3 How do I use it?
+The echo cancellor processes both the transmit and receive streams sample by
+sample. The processing function is not declared inline. Unfortunately,
+cancellation requires many operations per sample, so the call overhead is only a
+minor burden.

+/*! \page fsk_page FSK modems
+\section fsk_page_sec_1 What does it do?
+Most of the oldest telephony modems use incoherent FSK modulation. This module can
+be used to implement both the transmit and receive sides of a number of these
+modems. There are integrated definitions for:
+
+ - V.21
+ - V.23
+ - Bell 103
+ - Bell 202
+ - Weitbrecht (Used for TDD - Telecoms Device for the Deaf)
+
+The audio output or input is a stream of 16 bit samples, at 8000 samples/second.
+The transmit and receive sides can be used independantly.
+
+\section fsk_page_sec_2 The transmitter
+
+The FSK transmitter uses a DDS generator to synthesise the waveform. This
+naturally produces phase coherent transitions, as the phase update rate is
+switched, producing a clean spectrum. The symbols are not generally an integer
+number of samples long. However, the symbol time for the fastest data rate
+generally used (1200bps) is more than 7 samples long. The jitter resulting from
+switching at the nearest sample is, therefore, acceptable. No interpolation is
+used.
+
+\section fsk_page_sec_3 The receiver
+
+The FSK receiver uses a quadrature correlation technique to demodulate the
+signal. Two DDS quadrature oscillators are used. The incoming signal is
+correlated with the oscillator signals over a period of one symbol. The
+oscillator giving the highest net correlation from its I and Q outputs is the
+one that matches the frequency being transmitted during the correlation
+interval. Because the transmission is totally asynchronous, the demodulation
+process must run sample by sample to find the symbol transitions. The
+correlation is performed on a sliding window basis, so the computational load of
+demodulating sample by sample is not great.
+
+Two modes of symbol synchronisation are provided:
+
+ - In synchronous mode, symbol transitions are smoothed, to track their true
+ position in the prescence of high timing jitter. This provides the most
+ reliable symbol recovery in poor signal to noise conditions. However, it
+ takes a little time to settle, so it not really suitable for data streams
+ which must start up instantaneously (e.g. the TDD systems used by hearing
+ impaired people).
+
+ - In asynchronous mode each transition is taken at face value, with no temporal
+ smoothing. There is no settling time for this mode, but when the signal to
+ noise ratio is very poor it does not perform as well as the synchronous mode.

+/*! \page g711_page A-law and mu-law handling
+Lookup tables for A-law and u-law look attractive, until you consider the impact
+on the CPU cache. If it causes a substantial area of your processor cache to get
+hit too often, cache sloshing will severely slow things down. The main reason
+these routines are slow in C, is the lack of direct access to the CPU's "find
+the first 1" instruction. A little in-line assembler fixes that, and the
+conversion routines can be faster than lookup tables, in most real world usage.
+A "find the first 1" instruction is available on most modern CPUs, and is a
+much underused feature.
+
+If an assembly language method of bit searching is not available, these routines
+revert to a method that can be a little slow, so the cache thrashing might not
+seem so bad :(
+
+Feel free to submit patches to add fast "find the first 1" support for your own
+favourite processor.
+
+Look up tables are used for transcoding between A-law and u-law, since it is
+difficult to achieve the precise transcoding procedure laid down in the G.711
+specification by other means.

+ separate byte. (note that none of the parameters exceed 8 bits).
+ - Packed the the 33 byte per frame, used for VoIP, where 4 bits per frame are wasted.

+\section modem_connect_tones_page_sec_1 What does it do?
+Some telephony terminal equipment, such as modems, require a channel which is as
+clear as possible. They use their own echo cancellation. If the network is also
+performing echo cancellation the two cancellors can end up squabbling about the
+nature of the channel, with bad results. A special tone is defined which should
+cause the network to disable any echo cancellation processes. This is the echo
+canceller disable tone.
+
+The tone detector's design assumes the channel is free of any DC component.
+
+\section modem_connect_tones_page_sec_2 How does it work?
+A sharp notch filter is implemented as a single bi-quad section. The presence of
+the 2100Hz disable tone is detected by comparing the notched filtered energy
+with the unfiltered energy. If the notch filtered energy is much lower than the
+unfiltered energy, then a large proportion of the energy must be at the notch
+frequency. This type of detector may seem less intuitive than using a narrow
+bandpass filter to isolate the energy at the notch freqency. However, a sharp
+bandpass implemented as an IIR filter rings badly. The reciprocal notch filter
+is very well behaved for our purpose.

+/*! \page modem_echo_can_page Line echo cancellation for modems
+
+\section modem_echo_can_page_sec_1 What does it do?
+This module aims to cancel electrical echoes (e.g. from 2-4 wire hybrids)
+in modem applications. It is not very suitable for speech applications, which
+require additional refinements for satisfactory performance. It is, however, more
+efficient and better suited to modem applications.
+
+\section modem_echo_can_page_sec_2 How does it work?
+The heart of the echo cancellor is an adaptive FIR filter. This is adapted to
+match the impulse response of the environment being cancelled. It must be long
+enough to adequately cover the duration of that impulse response. The signal
+being transmitted into the environment being cancelled is passed through the
+FIR filter. The resulting output is an estimate of the echo signal. This is
+then subtracted from the received signal, and the result should be an estimate
+of the signal which originates within the environment being cancelled (people
+talking in the room, or the signal from the far end of a telephone line) free
+from the echos of our own transmitted signal.
+
+The FIR filter is adapted using the least mean squares (LMS) algorithm. This
+algorithm is attributed to Widrow and Hoff, and was introduced in 1960. It is
+the commonest form of filter adaption used in things like modem line equalisers
+and line echo cancellers. It works very well if the signal level is constant,
+which is true for a modem signal. To ensure good performa certain conditions must
+be met:
+
+ - The transmitted signal has weak self-correlation.
+ - There is no signal being generated within the environment being cancelled.
+
+The difficulty is that neither of these can be guaranteed. If the adaption is
+performed while transmitting noise (or something fairly noise like, such as
+voice) the adaption works very well. If the adaption is performed while
+transmitting something highly correlative (e.g. tones, like DTMF), the adaption
+can go seriously wrong. The reason is there is only one solution for the
+adaption on a near random signal. For a repetitive signal, there are a number of
+solutions which converge the adaption, and nothing guides the adaption to choose
+the correct one.
+
+\section modem_echo_can_page_sec_3 How do I use it?
+The echo cancellor processes both the transmit and receive streams sample by
+sample. The processing function is not declared inline. Unfortunately,
+cancellation requires many operations per sample, so the call overhead is only a
+minor burden.

+\section noise_page_sec_1 What does it do?
+It generates audio noise. Currently it only generates reasonable quality
+AWGN. It is designed to be of sufficiently low complexity to generate large
+volumes of reasonable quality noise, in real time.
+
+Hoth noise is used to model indoor ambient noise when evaluating communications
+systems such as telephones. It is named after D.F. Hoth, who made the first
+systematic study of this. The official definition of Hoth noise is IEEE
+standard 269-2001 (revised from 269-1992), "Draft Standard Methods for Measuring
+Transmission Performance of Analog and Digital Telephone Sets, Handsets and Headsets."
+
+The table below gives the spectral density of Hoth noise, adjusted in level to produce
+a reading of 50 dBA.

+/*! \page plc_page Packet loss concealment
+\section plc_page_sec_1 What does it do?
+The packet loss concealment module provides a synthetic fill-in signal, to minimise
+the audible effect of lost packets in VoIP applications. It is not tied to any
+particular codec, and could be used with almost any codec which does not
+specify its own procedure for packet loss concealment.
+
+Where a codec specific concealment procedure exists, that algorithm is usually built
+around knowledge of the characteristics of the particular codec. It will, therefore,
+generally give better results for that particular codec than this generic concealer will.
+
+The PLC code implements an algorithm similar to the one described in Appendix 1 of G.711.
+However, the G.711 algorithm is optimised for 10ms packets. Few people use such small
+packets. 20ms is a much more common value, and longer packets are also quite common. The
+algorithm has been adjusted with this in mind. Also, the G.711 approach causes an
+algorithmic delay, and requires significant buffer manipulation when there is no packet
+loss. The algorithm used here avoids this. It causes no delay, and achieves comparable
+quality with normal speech.
+
+Note that both this algorithm, and the one in G.711 are optimised for speech. For most kinds
+of music a much slower decay on bursts of lost packets give better results.
+
+\section plc_page_sec_2 How does it work?
+While good packets are being received, the plc_rx() routine keeps a record of the trailing
+section of the known speech signal. If a packet is missed, plc_fillin() is called to produce
+a synthetic replacement for the real speech signal. The average mean difference function
+(AMDF) is applied to the last known good signal, to determine its effective pitch.
+Based on this, the last pitch period of signal is saved. Essentially, this cycle of speech
+will be repeated over and over until the real speech resumes. However, several refinements
+are needed to obtain smooth pleasant sounding results.
+
+- The two ends of the stored cycle of speech will not always fit together smoothly. This can
+ cause roughness, or even clicks, at the joins between cycles. To soften this, the
+ 1/4 pitch period of real speech preceeding the cycle to be repeated is blended with the last
+ 1/4 pitch period of the cycle to be repeated, using an overlap-add (OLA) technique (i.e.
+ in total, the last 5/4 pitch periods of real speech are used).
+
+- The start of the synthetic speech will not always fit together smoothly with the tail of
+ real speech passed on before the erasure was identified. Ideally, we would like to modify
+ the last 1/4 pitch period of the real speech, to blend it into the synthetic speech. However,
+ it is too late for that. We could have delayed the real speech a little, but that would
+ require more buffer manipulation, and hurt the efficiency of the no-lost-packets case
+ (which we hope is the dominant case). Instead we use a degenerate form of OLA to modify
+ the start of the synthetic data. The last 1/4 pitch period of real speech is time reversed,
+ and OLA is used to blend it with the first 1/4 pitch period of synthetic speech. The result
+ seems quite acceptable.
+
+- As we progress into the erasure, the chances of the synthetic signal being anything like
+ correct steadily fall. Therefore, the volume of the synthesized signal is made to decay
+ linearly, such that after 50ms of missing audio it is reduced to silence.
+
+- When real speech resumes, an extra 1/4 pitch period of synthetic speech is blended with the
+ start of the real speech. If the erasure is small, this smoothes the transition. If the erasure
+ is long, and the synthetic signal has faded to zero, the blending softens the start up of the
+ real signal, avoiding a kind of "click" or "pop" effect that might occur with a sudden onset.
+
+\section plc_page_sec_3 How do I use it?
+Before audio is processed, call plc_init() to create an instance of the packet loss
+concealer. For each received audio packet that is acceptable (i.e. not including those being
+dropped for being too late) call plc_rx() to record the content of the packet. Note this may
+modify the packet a little after a period of packet loss, to blend real synthetic data smoothly.
+When a real packet is not available in time, call plc_fillin() to create a sythetic substitute.
+That's it!

+/*! \page sig_tone_page The signaling tone processor
+\section sig_tone_sec_1 What does it do?
+The signaling tone processor handles the 2280Hz, 2400Hz and 2600Hz tones, used
+in many analogue signaling procotols, and digital ones derived from them.
+
+\section sig_tone_sec_2 How does it work?
+Most single and two voice frequency signalling systems share many features, as these
+features have developed in similar ways over time, to address the limitations of
+early tone signalling systems.
+
+The usual practice is to start the generation of tone at a high energy level, so a
+strong signal is available at the receiver, for crisp tone detection. If the tone
+remains on for a significant period, the energy level is reduced, to minimise crosstalk.
+During the signalling transitions, only the tone is sent through the channel, and the media
+signal is suppressed. This means the signalling receiver has a very clean signal to work with,
+allowing for crisp detection of the signalling tone. However, when the signalling tone is on
+for extended periods, there may be supervisory information in the media signal, such as voice
+announcements. To allow these to pass through the system, the signalling tone is mixed with
+the media signal. It is the job of the signalling receiver to separate the signalling tone
+and the media. The necessary filtering may degrade the quality of the voice signal, but at
+least supervisory information may be heard.

+
+\section super_tone_rx_page_sec_2 How does it work?
+
+The supervisory tone detector is passed a series of data structures describing
+the tone patterns - the frequencies and cadencing - of the tones to be searched
+for. It constructs one or more Goertzel filters to monitor the required tones.
+If tones are close in frequency a single Goertzel set to the centre of the
+frequency range will be used. This optimises the efficiency of the detector. The
+Goertzel filters are applied without applying any special window functional
+(i.e. they use a rectangular window), so they have a sinc like response.
+However, for most tone patterns their rejection qualities are adequate.
+
+The detector aims to meet the need of the standard call progress tones, to
+ITU-T E.180/Q.35 (busy, dial, ringback, reorder). Also, the extended tones,
+to ITU-T E.180, Supplement 2 and EIA/TIA-464-A (recall dial tone, special
+ringback tone, intercept tone, call waiting tone, busy verification tone,
+executive override tone, confirmation tone).

+
+\section t30_page_sec_1 What does it do?
+The T.30 protocol is the core protocol used for FAX transmission. This module
+implements most of its key featrues. It does not interface to the outside work.
+Seperate modules do that for T.38, analogue line, and other forms of FAX
+communication.
+
+Current features of this module include:
+
+ - FAXing to and from multi-page TIFF/F files, whose images are one of the standard
+ FAX sizes.
+ - V.27ter, V.29 and V.17 modes (2400bps, to 14,400bps).
+ - T.4 1D (MH), T.4 2D,(MR) and T.6 (MMR) compression.
+ - Error correction mode (ECM).
+ - All standard horizonal resolutions (R8, R16, 300dpi, 600dpi, 800dpi, 1200dpi).
+ - All standard vertical resolutions (standard, fine, superfine, 300dpi, 600dpi, 800dpi, 1200dpi).
+ - All standard page widths (A4, B4, A3).
+ - All standard page lengths (A4, B4, North American letter, North American legal, continuous).
+ - Monitoring and sending identifier strings (CSI, TSI, and CIG).
+ - Monitoring and sending sub-address strings (SUB).
+ - Monitoring and sending polling sub-addresses (SEP).
+ - Monitoring and sending polled sub-addresses (PSA).
+ - Monitoring and sending sender identifications (SID).
+ - Monitoring and sending passwords (PWD).
+ - Monitoring of non-standard facility frames (NSF, NSC, and NSS).
+ - Sending custom non-standard facility frames (NSF, NSC, and NSS).
+ - Analogue modem and T.38 operation.
+
+\section t30_page_sec_2 How does it work?
+
+Some of the following is paraphrased from some notes found a while ago on the Internet.
+I cannot remember exactly where they came from, but they are useful.
+
+\subsection t30_page_sec_2a The answer (CED) tone
+
+The T.30 standard says an answering fax device must send CED (a 2100Hz tone) for
+approximately 3 seconds before sending the first handshake message. Some machines
+send an 1100Hz or 1850Hz tone, and some send no tone at all. In fact, this answer
+tone is so unpredictable, it cannot really be used. It should, however, always be
+generated according to the specification.
+
+\subsection t30_page_sec_2b Common Timing Deviations
+
+The T.30 spec. specifies a number of time-outs. For example, after dialing a number,
+a calling fax system should listen for a response for 35 seconds before giving up.
+These time-out periods are as follows:
+
+ - T1 - 35+-5s: the maximum time for which two fax system will attempt to identify each other
+ - T2 - 6+-1s: a time-out used to start the sequence for changing transmit parameters
+ - T3 - 10+-5s: a time-out used in handling operator interrupts
+ - T5 - 60+-5s: a time-out used in error correction mode
+
+These time-outs are sometimes misinterpreted. In addition, they are routinely
+ignored, sometimes with good reason. For example, after placing a call, the
+calling fax system is supposed to wait for 35 seconds before giving up. If the
+answering unit does not answer on the first ring or if a voice answering machine
+is connected to the line, or if there are many delays through the network,
+the delay before answer can be much longer than 35 seconds.
+
+Fax units that support error correction mode (ECM) can respond to a post-image
+handshake message with a receiver not ready (RNR) message. The calling unit then
+queries the receiving fax unit with a receiver ready (RR) message. If the
+answering unit is still busy (printing for example), it will repeat the RNR
+message. According to the T.30 standard, this sequence (RR/RNR RR/RNR) can be
+repeated for up to the end of T5 (60+-5s). However, many fax systems
+ignore the time-out and will continue the sequence indefinitely, unless the user
+manually overrides.
+
+All the time-outs are subject to alteration, and sometimes misuse. Good T.30
+implementations must do the right thing, and tolerate others doing the wrong thing.
+
+\subsection t30_page_sec_2c Variations in the inter-carrier gap
+
+T.30 specifies 75+-20ms of silence between signals using different modulation
+schemes. Examples are between the end of a DCS signal and the start of a TCF signal,
+and between the end of an image and the start of a post-image signal. Many fax systems
+violate this requirement, especially for the silent period between DCS and TCF.
+This may be stretched to well over 100ms. If this period is too long, it can interfere with
+handshake signal error recovery, should a packet be corrupted on the line. Systems
+should ensure they stay within the prescribed T.30 limits, and be tolerant of others
+being out of spec..
+
+\subsection t30_page_sec_2d Other timing variations
+
+Testing is required to determine the ability of a fax system to handle
+variations in the duration of pauses between unacknowledged handshake message
+repetitions, and also in the pauses between the receipt of a handshake command and
+the start of a response to that command. In order to reduce the total
+transmission time, many fax systems start sending a response message before the
+end of the command has been received.
+
+\subsection t30_page_sec_2e Other deviations from the T.30 standard
+
+There are many other commonly encountered variations between machines, including:
+
+ - frame sequence deviations
+ - preamble and flag sequence variations
+ - improper EOM usage
+ - unusual data rate fallback sequences
+ - common training pattern detection algorithms
+ - image transmission deviations
+ - use of the talker echo protect tone
+ - image padding and short lines
+ - RTP/RTN handshake message usage
+ - long duration lines
+ - nonstandard disconnect sequences
+ - DCN usage

+
+/*! \page t38_core_page T.38 real time FAX over IP message handling
+There are two ITU recommendations which address sending FAXes over IP networks. T.37 specifies a
+method of encapsulating FAX images in e-mails, and transporting them to the recipient (an e-mail
+box, or another FAX machine) in a store-and-forward manner. T.38 defines a protocol for
+transmitting a FAX across an IP network in real time. The core T.38 modules implements the basic
+message handling for the T.38, real time, FAX over IP (FoIP) protocol.
+
+The T.38 protocol can operate between:
+ - Internet-aware FAX terminals, which connect directly to an IP network. The T.38 terminal module
+ extends this module to provide a complete T.38 terminal.
+ - FAX gateways, which allow traditional PSTN FAX terminals to communicate through the Internet.
+ The T.38 gateway module extends this module to provide a T.38 gateway.
+ - A combination of terminals and gateways.
+
+T.38 is the only standardised protocol which exists for real-time FoIP. Reliably transporting a
+FAX between PSTN FAX terminals, through an IP network, requires use of the T.38 protocol at FAX
+gateways. VoIP connections are not robust for modem use, including FAX modem use. Most use low
+bit rate codecs, which cannot convey the modem signals accurately. Even when high bit rate
+codecs are used, VoIP connections suffer dropouts and timing adjustments, which modems cannot
+tolerate. In a LAN environment the dropout rate may be very low, but the timing adjustments which
+occur in VoIP connections still make modem operation unreliable. T.38 FAX gateways deal with the
+delays, timing jitter, and packet loss experienced in packet networks, and isolate the PSTN FAX
+terminals from these as far as possible. In addition, by sending FAXes as image data, rather than
+digitised audio, they reduce the required bandwidth of the IP network.
+
+\section t38_core_page_sec_1 What does it do?
+
+\section t38_core_page_sec_2 How does it work?
+
+Timing differences and jitter between two T.38 entities can be a serious problem, if one of those
+entities is a PSTN gateway.
+
+Flow control for non-ECM image data takes advantage of several features of the T.30 specification.
+First, an unspecified number of 0xFF octets may be sent at the start of transmission. This means we
+can add endless extra 0xFF bytes at this point, without breaking the T.30 spec. In practice, we
+cannot add too many, or we will affect the timing tolerance of the T.30 protocol by delaying the
+response at the end of each image. Secondly, just before an end of line (EOL) marker we can pad
+with zero bits. Again, the number is limited only by need to avoid upsetting the timing of the
+step following the non-ECM data.

+/*! \page time_scale_page Time scaling speech
+\section time_scale_page_sec_1 What does it do?
+The time scaling module allows speech files to be played back at a
+different speed from the speed at which they were recorded. If this
+were done by simply speeding up or slowing down replay, the pitch of
+the voice would change, and sound very odd. This module keeps the pitch
+of the voice at its original level.
+
+The speed of the voice may be altered over a wide range. However, the practical
+useful rates are between about half normal speed and twice normal speed.
+
+\section time_scale_page_sec_2 How does it work?
+The time scaling module is based on the Pointer Interval Controlled
+OverLap and Add (PICOLA) method, developed by Morita Naotaka.
+Mikio Ikeda has an excellent web page on this subject at
+http://keizai.yokkaichi-u.ac.jp/~ikeda/research/picola.html
+There is also working code there. This implementation uses
+exactly the same algorithms, but the code is a complete rewrite.
+Mikio's code batch processes files. This version works incrementally
+on streams, and allows multiple streams to be processed concurrently.
+
+\section time_scale_page_sec_3 How do I used it?
+The output buffer must be big enough to hold the maximum number of samples which
+could result from the data in the input buffer, which is:
+
+ input_len*playout_rate + sample_rate/TIME_SCALE_MIN_PITCH + 1

+/*! \page v17rx_page The V.17 receiver
+\section v17rx_page_sec_1 What does it do?
+The V.17 receiver implements the receive side of a V.17 modem. This can operate
+at data rates of 14400, 12000, 9600 and 7200 bits/second. The audio input is a stream
+of 16 bit samples, at 8000 samples/second. The transmit and receive side of V.17
+modems operate independantly. V.17 is mostly used for FAX transmission over PSTN
+lines, where it provides the standard 14400 bits/second rate.
+
+\section v17rx_page_sec_2 How does it work?
+V.17 uses QAM modulation, at 2400 baud, and trellis coding. Constellations with
+16, 32, 64, and 128 points are defined. After one bit per baud is absorbed by the
+trellis coding, this gives usable bit rates of 7200, 9600, 12000, and 14400 per
+second.
+
+V.17 specifies a training sequence at the start of transmission, which makes the
+design of a V.17 receiver relatively straightforward. The first stage of the
+training sequence consists of 256
+symbols, alternating between two constellation positions. The receiver monitors
+the signal power, to sense the possible presence of a valid carrier. When the
+alternating signal begins, the power rising above a minimum threshold (-43dBm0)
+causes the main receiver computation to begin. The initial measured power is
+used to quickly set the gain of the receiver. After this initial settling, the
+front end gain is locked, and the adaptive equalizer tracks any subsequent
+signal level variation. The signal is oversampled to 24000 samples/second (i.e.
+signal, zero, zero, signal, zero, zero, ...) and fed to a complex root raised
+cosine pulse shaping filter. This filter has been modified from the conventional
+root raised cosine filter, by shifting it up the band, to be centred at the nominal
+carrier frequency. This filter interpolates the samples, pulse shapes, and performs
+a fractional sample delay at the same time. 192 sets of filter coefficients are used
+to achieve a set of finely spaces fractional sample delays, between zero and
+one sample. By choosing every fifth sample, and the appropriate set of filter
+coefficients, the properly tuned symbol tracker can select data samples at 4800
+samples/second from points within 0.28 degrees of the centre and mid-points of
+each symbol. The output of the filter is multiplied by a complex carrier, generated
+by a DDS. The result is a baseband signal, requiring no further filtering, apart from
+an adaptive equalizer. The baseband signal is fed to a T/2 adaptive equalizer.
+A band edge component maximisation algorithm is used to tune the sampling, so the samples
+fed to the equalizer are close to the mid point and edges of each symbol. Initially
+the algorithm is very lightly damped, to ensure the symbol alignment pulls in
+quickly. Because the sampling rate will not be precisely the same as the
+transmitter's (the spec. says the symbol timing should be within 0.01%), the
+receiver constantly evaluates and corrects this sampling throughout its
+operation. During the symbol timing maintainence phase, the algorithm uses
+a heavier damping.
+
+The carrier is specified as 1800Hz +- 1Hz at the transmitter, and 1800 +-7Hz at
+the receiver. The receive carrier would only be this inaccurate if the link
+includes FDM sections. These are being phased out, but the design must still
+allow for the worst case. Using an initial 1800Hz signal for demodulation gives
+a worst case rotation rate for the constellation of about one degree per symbol.
+Once the symbol timing synchronisation algorithm has been given time to lock to the
+symbol timing of the initial alternating pattern, the phase of the demodulated signal
+is recorded on two successive symbols - once for each of the constellation positions.
+The receiver then tracks the symbol alternations, until a large phase jump occurs.
+This signifies the start of the next phase of the training sequence. At this
+point the total phase shift between the original recorded symbol phase, and the
+symbol phase just before the phase jump occurred is used to provide a coarse
+estimation of the rotation rate of the constellation, and it current absolute
+angle of rotation. These are used to update the current carrier phase and phase
+update rate in the carrier DDS. The working data already in the pulse shaping
+filter and equalizer buffers is given a similar step rotation to pull it all
+into line. From this point on, a heavily damped integrate and dump approach,
+based on the angular difference between each received constellation position and
+its expected position, is sufficient to track the carrier, and maintain phase
+alignment. A fast rough approximator for the arc-tangent function is adequate
+for the estimation of the angular error.
+
+The next phase of the training sequence is a scrambled sequence of two
+particular symbols. We train the T/2 adaptive equalizer using this sequence. The
+scrambling makes the signal sufficiently diverse to ensure the equalizer
+converges to the proper generalised solution. At the end of this sequence, the
+equalizer should be sufficiently well adapted that is can correctly resolve the
+full QAM constellation. However, the equalizer continues to adapt throughout
+operation of the modem, fine tuning on the more complex data patterns of the
+full QAM constellation.
+
+In the last phase of the training sequence, the modem enters normal data
+operation, with a short defined period of all ones as data. As in most high
+speed modems, data in a V.17 modem passes through a scrambler, to whiten the
+spectrum of the signal. The transmitter should initialise its data scrambler,
+and pass the ones through it. At the end of the ones, real data begins to pass
+through the scrambler, and the transmit modem is in normal operation. The
+receiver tests that ones are really received, in order to verify the modem
+trained correctly. If all is well, the data following the ones is fed to the
+application, and the receive modem is up and running. Unfortunately, some
+transmit side of some real V.17 modems fail to initialise their scrambler before
+sending the ones. This means the first 23 received bits (the length of the
+scrambler register) cannot be trusted for the test. The receive modem,
+therefore, only tests that bits starting at bit 24 are really ones.
+
+The V.17 signal is trellis coded. Two bits of each symbol are convolutionally coded
+to form a 3 bit trellis code - the two original bits, plus an extra redundant bit. It
+is possible to ignore the trellis coding, and just decode the non-redundant bits.
+However, the noise performance of the receiver would suffer. Using a proper
+trellis decoder adds several dB to the noise tolerance to the receiving modem. Trellis
+coding seems quite complex at first sight, but is fairly straightforward once you
+get to grips with it.
+
+Trellis decoding tracks the data in terms of the possible states of the convolutional
+coder at the transmitter. There are 8 possible states of the V.17 coder. The first
+step in trellis decoding is to find the best candidate constellation point
+for each of these 8 states. One of thse will be our final answer. The constellation
+has been designed so groups of 8 are spread fairly evenly across it. Locating them
+is achieved is a reasonably fast manner, by looking up the answers in a set of space
+map tables. The disadvantage is the tables are potentially large enough to affect
+cache performance. The trellis decoder works over 16 successive symbols. The result
+of decoding is not known until 16 symbols after the data enters the decoder. The
+minimum total accumulated mismatch between each received point and the actual
+constellation (termed the distance) is assessed for each of the 8 states. A little
+analysis of the coder shows that each of the 8 current states could be arrived at
+from 4 different previous states, through 4 different constellation bit patterns.
+For each new state, the running total distance is arrived at by inspecting a previous
+total plus a new distance for the appropriate 4 previous states. The minimum of the 4
+values becomes the new distance for the state. Clearly, a mechanism is needed to stop
+this distance from growing indefinitely. A sliding window, and several other schemes
+are possible. However, a simple single pole IIR is very simple, and provides adequate
+results.
+
+For each new state we store the constellation bit pattern, or path, to that state, and
+the number of the previous state. We find the minimum distance amongst the 8 new
+states for each new symbol. We then trace back through the states, until we reach the
+one 16 states ago which leads to the current minimum distance. The bit pattern stored
+there is the error corrected bit pattern for that symbol.
+
+So, what does Trellis coding actually achieve? TCM is easier to understand by looking
+at the V.23bis modem spec. The V.32bis spec. is very similar to V.17, except that it
+is a full duplex modem and has non-TCM options, as well as the TCM ones in V.17.
+
+V32bis defines two options for pumping 9600 bits per second down a phone line - one
+with and one without TCM. Both run at 2400 baud. The non-TCM one uses simple 16 point
+QAM on the raw data. The other takes two out of every four raw bits, and convolutionally
+encodes them to 3. Now we have 5 bits per symbol, and we need 32 point QAM to send the
+data.
+
+The raw error rate from simple decoding of the 32 point QAM is horrible compared to
+decoding the 16 point QAM. If a point decoded from the 32 point QAM is wrong, the likely
+correct choice should be one of the adjacent ones. It is unlikely to have been one that
+is far away across the constellation, unless there was a huge noise spike, interference,
+or something equally nasty. Now, the 32 point symbols do not exist in isolation. There
+was a kind of temporal smearing in the convolutional coding. It created a well defined
+dependency between successive symbols. If we knew for sure what the last few symbols
+were, they would lead us to a limited group of possible values for the current symbol,
+constrained by the behaviour of the convolutional coder. If you look at how the symbols
+were mapped to constellation points, you will see the mapping tries to spread those
+possible symbols as far apart as possible. This will leave only one that is pretty
+close to the received point, which must be the correct choice. However, this assumes
+we know the last few symbols for sure. Since we don't, we have a bit more work to do
+to achieve reliable decoding.
+
+Instead of decoding to the nearest point on the constellation, we decode to a group of
+likely constellation points in the neighbourhood of the received point. We record the
+mismatch for each - that is the distance across the constellation between the received
+point and the group of nearby points. To avoid square roots, recording x2 + y2 can be
+good enough. Symbol by symbol, we record this information. After a few symbols we can
+stand back and look at the recorded information.
+
+For each symbol we have a set of possible symbol values and error metric pairs. The
+dependency between symbols, created by the convolutional coder, means some paths from
+symbol to symbol are possible and some are not. It we trace back through the possible
+symbol to symbol paths, and total up the error metric through those paths, we end up
+with a set of figures of merit (or more accurately figures of demerit, since
+larger == worse) for the likelihood of each path being the correct one. The path with
+the lowest total metric is the most likely, and gives us our final choice for what we
+think the current symbol really is.
+
+That was hard work. It takes considerable computation to do this selection and traceback,
+symbol by symbol. We need to get quite a lot from this. It needs to drive the error rate
+down so far that is compensates for the much higher error rate due to the larger
+constellation, and then buys us some actual benefit. Well in the example we are looking
+at - V.32bis at 9600bps - it works out the error rate from the TCM option is like using
+the non-TCM option with several dB more signal to noise ratio. That's nice. The non-TCM
+option is pretty reasonable on most phone lines, but a better error rate is always a
+good thing. However, V32bis includes a 14,400bps option. That uses 2400 baud, and 6 bit
+symbols. Convolutional encoding increases that to 7 bits per symbol, by taking 2 bits and
+encoding them to 3. This give a 128 point QAM constellation. Again, the difference between
+using this, and using just an uncoded 64 point constellation is equivalent to maybe 5dB of
+extra signal to noise ratio. However, in this case it is the difference between the modem
+working only on the most optimal lines, and being widely usable across most phone lines.
+TCM absolutely transformed the phone line modem business.

+/*! \page v17tx_page The V.17 transmitter
+\section v17tx_page_sec_1 What does it do?
+The V.17 transmitter implements the transmit side of a V.17 modem. This can
+operate at data rates of 14400, 12000, 9600 and 7200 bits/second. The audio
+output is a stream of 16 bit samples, at 8000 samples/second. The transmit and
+receive side of V.17 modems operate independantly. V.17 is mostly used for FAX
+transmission, where it provides the standard 14400 bits/second rate.
+
+\section v17tx_page_sec_2 How does it work?
+V.17 uses QAM modulation and trellis coding. The data to be transmitted is
+scrambled, to whiten it. The least significant 2 bits of each symbol are then
+differentially encoded, using a simple lookup approach. The resulting 2 bits are
+convolutionally encoded, producing 3 bits. The extra bit is the redundant bit
+of the trellis code. The other bits of the symbol pass by the differential
+and convolutional coding unchanged. The resulting bits define the constellation
+point to be transmitted for the symbol. The redundant bit doubles the size of the
+constellation, and so increases the error rate for detecting individual symbols
+at the receiver. However, when a number of successive symbols are processed at
+the receiver, the redundancy actually provides several dB of improved error
+performance.
+
+The standard method of producing a QAM modulated signal is to use a sampling
+rate which is a multiple of the baud rate. The raw signal is then a series of
+complex pulses, each an integer number of samples long. These can be shaped,
+using a suitable complex filter, and multiplied by a complex carrier signal
+to produce the final QAM signal for transmission.
+
+The pulse shaping filter is only vaguely defined by the V.17 spec. Some of the
+other ITU modem specs. fully define the filter, typically specifying a root
+raised cosine filter, with 50% excess bandwidth. This is a pity, since it
+increases the variability of the received signal. However, the receiver's
+adaptive equalizer will compensate for these differences. The current
+design uses a root raised cosine filter with 25% excess bandwidth. Greater
+excess bandwidth will not allow the tranmitted signal to meet the spectral
+requirements.
+
+The sampling rate for our transmitter is defined by the channel - 8000 per
+second. This is not a multiple of the baud rate (i.e. 2400 baud). The baud
+interval is actually 10/3 sample periods. Instead of using a symmetric
+FIR to pulse shape the signal, a polyphase filter is used. This consists of
+10 sets of coefficients, offering zero to 9/10ths of a baud phase shift as well
+as root raised cosine filtering. The appropriate coefficient set is chosen for
+each signal sample generated.
+
+The carrier is generated using the DDS method. Using two second order resonators,
+started in quadrature, might be more efficient, as it would have less impact on
+the processor cache than a table lookup approach. However, the DDS approach
+suits the receiver better, so the same signal generator is also used for the
+transmitter.

+\section v22bis_page_sec_1 What does it do?
+The V.22bis modem is a duplex modem for general data use on the PSTN, at rates
+of 1200 and 2400 bits/second. It is a compatible extension of the V.22 modem,
+which is a 1200 bits/second only design. It is a band-split design, using carriers
+of 1200Hz and 2400Hz. It is the fastest PSTN modem in general use which does not
+use echo-cancellation.
+
+\section v22bis__page_sec_2 How does it work?
+V.22bis uses 4PSK modulation at 1200 bits/second or 16QAM modulation at 2400
+bits/second. At 1200bps the symbols are so long that a fixed compromise equaliser
+is sufficient to recover the 4PSK signal reliably. At 2400bps an adaptive
+equaliser is necessary.
+
+The V.22bis training sequence includes sections which allow the modems to determine
+if the far modem can support (or is willing to support) 2400bps operation. The
+modems will automatically use 2400bps if both ends are willing to use that speed,
+or 1200bps if one or both ends to not acknowledge that 2400bps is OK.

+The V.27ter receiver implements the receive side of a V.27ter modem. This can operate

+
+\section v27ter_rx_page_sec_2 How does it work?
+V.27ter defines two modes of operation. One uses 8-PSK at 1600 baud, giving 4800bps.
+The other uses 4-PSK at 1200 baud, giving 2400bps. A training sequence is specified
+at the start of transmission, which makes the design of a V.27ter receiver relatively
+straightforward.

+\section v27ter_tx_page_sec_1 What does it do?
+The V.27ter transmitter implements the transmit side of a V.27ter modem. This
+can operate at data rates of 4800 and 2400 bits/s. The audio output is a stream
+of 16 bit samples, at 8000 samples/second. The transmit and receive side of
+V.27ter modems operate independantly. V.27ter is used for FAX transmission,
+where it provides the standard 4800 and 2400 bits/s rates.
+
+\section v27ter_tx_page_sec_2 How does it work?
+V.27ter uses DPSK modulation. A common method of producing a DPSK modulated
+signal is to use a sampling rate which is a multiple of the baud rate. The raw
+signal is then a series of complex pulses, each an integer number of samples
+long. These can be shaped, using a suitable complex filter, and multiplied by a
+complex carrier signal to produce the final DPSK signal for transmission.
+
+The pulse shaping filter for V.27ter is defined in the spec. It is a root raised
+cosine filter with 50% excess bandwidth.
+
+The sampling rate for our transmitter is defined by the channel - 8000 samples/s.
+This is a multiple of the baud rate at 4800 bits/s (8-PSK at 1600 baud, 5 samples per
+symbol), but not at 2400 bits/s (4-PSK at 1200 baud, 20/3 samples per symbol). The baud
+interval is actually 20/3 sample periods at 2400bis/s. A symmetric FIR is used to
+apply root raised cosine filtering in the 4800bits/s mode. In the 2400bits/s mode
+a polyphase FIR filter is used. This consists of 20 sets of coefficients, offering
+zero to 19/20ths of a baud phase shift as well as root raised cosine filtering.
+The appropriate coefficient set is chosen for each signal sample generated.
+
+The carrier is generated using the DDS method. Using 2 second order resonators,
+started in quadrature, might be more efficient, as it would have less impact on
+the processor cache than a table lookup approach. However, the DDS approach
+suits the receiver better, so then same signal generator is also used for the
+transmitter.

+/*! \page v29rx_page The V.29 receiver
+\section v29rx_page_sec_1 What does it do?
+The V.29 receiver implements the receive side of a V.29 modem. This can operate
+at data rates of 9600, 7200 and 4800 bits/s. The audio input is a stream of 16
+bit samples, at 8000 samples/second. The transmit and receive side of V.29
+modems operate independantly. V.29 is mostly used for FAX transmission, where it
+provides the standard 9600 and 7200 bits/s rates (the 4800 bits/s mode is not
+used for FAX).
+
+\section v29rx_page_sec_2 How does it work?
+V.29 operates at 2400 baud for all three bit rates. It uses 16-QAM modulation for
+9600bps, 8-QAM for 7200bps, and 4-PSK for 4800bps. A training sequence is specified
+at the start of transmission, which makes the design of a V.29 receiver relatively
+straightforward.
+
+The first stage of the training sequence consists of 128
+symbols, alternating between two constellation positions. The receiver monitors
+the signal power, to sense the possible presence of a valid carrier. When the
+alternating signal begins, the power rising above a minimum threshold (-26dBm0)
+causes the main receiver computation to begin. The initial measured power is
+used to quickly set the gain of the receiver. After this initial settling, the
+front end gain is locked, and the adaptive equalizer tracks any subsequent
+signal level variation. The signal is oversampled to 24000 samples/second (i.e.
+signal, zero, zero, signal, zero, zero, ...) and fed to a complex root raised
+cosine pulse shaping filter. This filter has been modified from the conventional
+root raised cosine filter, by shifting it up the band, to be centred at the nominal
+carrier frequency. This filter interpolates the samples, pulse shapes, and performs
+a fractional sample delay at the same time. 48 sets of filter coefficients are used to
+achieve a set of finely spaces fractional sample delays, between zero and
+one sample. By choosing every fifth sample, and the appropriate set of filter
+coefficients, the properly tuned symbol tracker can select data samples at 4800
+samples/second from points within 1.125 degrees of the centre and mid-points of
+each symbol. The output of the filter is multiplied by a complex carrier, generated
+by a DDS. The result is a baseband signal, requiring no further filtering, apart from
+an adaptive equalizer. The baseband signal is fed to a T/2 adaptive equalizer.
+A band edge component maximisation algorithm is used to tune the sampling, so the samples
+fed to the equalizer are close to the mid point and edges of each symbol. Initially
+the algorithm is very lightly damped, to ensure the symbol alignment pulls in
+quickly. Because the sampling rate will not be precisely the same as the
+transmitter's (the spec. says the symbol timing should be within 0.01%), the
+receiver constantly evaluates and corrects this sampling throughout its
+operation. During the symbol timing maintainence phase, the algorithm uses
+a heavier damping.
+
+The carrier is specified as 1700Hz +-1Hz at the transmitter, and 1700 +-7Hz at
+the receiver. The receive carrier would only be this inaccurate if the link
+includes FDM sections. These are being phased out, but the design must still
+allow for the worst case. Using an initial 1700Hz signal for demodulation gives
+a worst case rotation rate for the constellation of about one degree per symbol.
+Once the symbol timing synchronisation algorithm has been given time to lock to
+the symbol timing of the initial alternating pattern, the phase of the demodulated
+signal is recorded on two successive symbols - once for each of the constellation
+positions. The receiver then tracks the symbol alternations, until a large phase jump
+occurs. This signifies the start of the next phase of the training sequence. At this
+point the total phase shift between the original recorded symbol phase, and the
+symbol phase just before the phase jump occurred is used to provide a coarse
+estimation of the rotation rate of the constellation, and it current absolute
+angle of rotation. These are used to update the current carrier phase and phase
+update rate in the carrier DDS. The working data already in the pulse shaping
+filter and equalizer buffers is given a similar step rotation to pull it all
+into line. From this point on, a heavily damped integrate and dump approach,
+based on the angular difference between each received constellation position and
+its expected position, is sufficient to track the carrier, and maintain phase
+alignment. A fast rough approximator for the arc-tangent function is adequate
+for the estimation of the angular error.
+
+The next phase of the training sequence is a scrambled sequence of two
+particular symbols. We train the T/2 adaptive equalizer using this sequence. The
+scrambling makes the signal sufficiently diverse to ensure the equalizer
+converges to the proper generalised solution. At the end of this sequence, the
+equalizer should be sufficiently well adapted that is can correctly resolve the
+full QAM constellation. However, the equalizer continues to adapt throughout
+operation of the modem, fine tuning on the more complex data patterns of the
+full QAM constellation.
+
+In the last phase of the training sequence, the modem enters normal data
+operation, with a short defined period of all ones as data. As in most high
+speed modems, data in a V.29 modem passes through a scrambler, to whiten the
+spectrum of the signal. The transmitter should initialise its data scrambler,
+and pass the ones through it. At the end of the ones, real data begins to pass
+through the scrambler, and the transmit modem is in normal operation. The
+receiver tests that ones are really received, in order to verify the modem
+trained correctly. If all is well, the data following the ones is fed to the
+application, and the receive modem is up and running. Unfortunately, some
+transmit side of some real V.29 modems fail to initialise their scrambler before
+sending the ones. This means the first 23 received bits (the length of the
+scrambler register) cannot be trusted for the test. The receive modem,
+therefore, only tests that bits starting at bit 24 are really ones.

+/*! \page v29tx_page The V.29 transmitter
+\section v29tx_page_sec_1 What does it do?
+The V.29 transmitter implements the transmit side of a V.29 modem. This can
+operate at data rates of 9600, 7200 and 4800 bits/s. The audio output is a
+stream of 16 bit samples, at 8000 samples/second. The transmit and receive side
+of V.29 modems operate independantly. V.29 is mostly used for FAX transmission,
+where it provides the standard 9600 and 7200 bits/s rates (the 4800 bits/s mode
+is not used for FAX).
+
+\section v29tx_page_sec_2 How does it work?
+V.29 uses QAM modulation. The standard method of producing a QAM modulated
+signal is to use a sampling rate which is a multiple of the baud rate. The raw
+signal is then a series of complex pulses, each an integer number of samples
+long. These can be shaped, using a suitable complex filter, and multiplied by a
+complex carrier signal to produce the final QAM signal for transmission.
+
+The pulse shaping filter is only vaguely defined by the V.29 spec. Some of the
+other ITU modem specs. fully define the filter, typically specifying a root
+raised cosine filter, with 50% excess bandwidth. This is a pity, since it
+increases the variability of the received signal. However, the receiver's
+adaptive equalizer will compensate for these differences. The current
+design uses a root raised cosine filter with 25% excess bandwidth. Greater
+excess bandwidth will not allow the tranmitted signal to meet the spectral
+requirements.
+
+The sampling rate for our transmitter is defined by the channel - 8000 per
+second. This is not a multiple of the baud rate (i.e. 2400 baud). The baud
+interval is actually 10/3 sample periods. Instead of using a symmetric
+FIR to pulse shape the signal, a polyphase filter is used. This consists of
+10 sets of coefficients, offering zero to 9/10ths of a baud phase shift as well
+as root raised cosine filtering. The appropriate coefficient set is chosen for
+each signal sample generated.
+
+The carrier is generated using the DDS method. Using two second order resonators,
+started in quadrature, might be more efficient, as it would have less impact on
+the processor cache than a table lookup approach. However, the DDS approach
+suits the receiver better, so the same signal generator is also used for the
+transmitter.
+
+The equation defining QAM modulation is:
+
+ s(n) = A*cos(2*pi*f*n + phi(n))
+
+where phi(n) is the phase of the information, and A is the amplitude of the information
+
+using the identity
+
+ cos(x + y) = cos(x)*cos(y) - sin(x)*sin(y)
+
+we get
+
+ s(n) = A {cos(2*pi*f*n)*cos(phi(n)) - sin(2*pi*f*n)*sin(phi(n))}
+
+substituting with the constellation positions
+
+ I(n) = A*cos(phi(n))
+ Q(n) = A*sin(phi(n))
+
+gives
+
+ s(n) = I(n)*cos(2*pi*f*n) - Q(n)*sin(2*pi*f*n)

+ * Country code first byte, then manufacturer is last two bytes. See T.35.
+ * Apparently Germany issued some manufacturer codes before the two-byte
+ * standard was accepted, and so some few German manufacturers are
+ * identified by a single manufacturer byte.
+ *
+ * T.30 5.3.6.2.7 (2003) states that the NSF FIF is transmitted
+ * in MSB2LSB order. Revisions of T.30 prior to 2003 did not
+ * contain explicit specification as to the transmit bit order.
+ * (Although it did otherwise state that all HDLC frame data should
+ * be in MSB order except as noted.) Because CSI, TSI, and other
+ * prologue frames were in LSB order by way of an exception to the
+ * general rule (T.30 5.3.6.2.4-11) many manufacturers assumed that
+ * NSF should also be in LSB order. Consequently there will be
+ * some country-code "masquerading" as a terminal may use the
+ * proper country-code, but with an inverted bit order.
+ *
+ * Thus, country code x61 (Korea) turns into x86 (Papua New Guinea),
+ * code xB5 (USA) turns into xAD (Tunisia), code x26 (China) turns
+ * into x64 (Lebanon), code x04 (Germany) turns into x20 (Canada),
+ * and code x3D (France) turns into xBC (Vietnam).
+ *
+ * For the most part it should be safe to identify a manufacturer
+ * both with the MSB and LSB ordered bits, as the "masqueraded" country
+ * is likely to not be actively assigning T.38 manufacturer codes.
+ * However, some manufacturers (e.g. Microsoft) may use MSB for the
+ * country code and LSB for the rest of the NSF, and so basically this
+ * table must be verified and corrected against actual real-world
+ * results.

+ words H + M(a0a1) + M(a1a2). H is the flag code word 001 taken from the two-dimensional

+ of the runs a0a1 and a1a2 respectively and are taken from the appropriate white or black

+The basic method used by the V.22bis receiver is:
+
+ Put each sample into the pulse-shaping and phase shift filter buffer
+
+ At T/2 rate:
+ Filter and demodulate the contents of the input filter buffer, producing a sample
+ in the equalizer filter buffer.
+
+ Tune the symbol timing based on the latest 3 samples in the equalizer buffer. This
+ updates the decision points for taking the T/2 samples.
+
+ Equalize the contents of the equalizer buffer, producing a demodulated constellation
+ point.
+
+ Find the nearest constellation point to the received position. This is our received
+ symbol.
+
+ Tune the local carrier, based on the angular mismatch between the actual signal and
+ the decision.
+
+ Tune the equalizer, based on the mismatch between the actual signal and the decision.
+
+ Descramble and output the bits represented by the decision.

+6.3.1.1 Interworking at 2400 bit/s
+
+6.3.1.1.1 Calling modem
+
+a) On connection to line the calling modem shall be conditioned to receive signals
+ in the high channel at 1200 bit/s and transmit signals in the low channel at 1200 bit/s
+ in accordance with section 2.5.2.2. It shall apply an ON condition to circuit 107 in accordance
+ with Recommendation V.25. The modem shall initially remain silent.
+
+b) After 155 +-10 ms of unscrambled binary 1 has been detected, the modem shall remain silent
+ for a further 456 +-10 ms then transmit an unscrambled repetitive double dibit pattern of 00
+ and 11 at 1200 bit/s for 100 +-3 ms. Following this signal the modem shall transmit scrambled
+ binary 1 at 1200 bit/s.
+
+c) If the modem detects scrambled binary 1 in the high channel at 1200 bit/s for 270 +-40 ms,
+ the handshake shall continue in accordance with section 6.3.1.2.1 c) and d). However, if unscrambled
+ repetitive double dibit 00 and 11 at 1200 bit/s is detected in the high channel, then at the
+ end of receipt of this signal the modem shall apply an ON condition to circuit 112.
+
+d) 600 +-10 ms after circuit 112 has been turned ON the modem shall begin transmitting scrambled
+ binary 1 at 2400 bit/s, and 450 +-10 ms after circuit 112 has been turned ON the receiver may
+ begin making 16-way decisions.
+
+e) Following transmission of scrambled binary 1 at 2400 bit/s for 200 +-10 ms, circuit 106 shall
+ be conditioned to respond to circuit 105 and the modem shall be ready to transmit data at
+ 2400 bit/s.
+
+f) When 32 consecutive bits of scrambled binary 1 at 2400 bit/s have been detected in the high
+ channel the modem shall be ready to receive data at 2400 bit/s and shall apply an ON condition
+ to circuit 109.
+
+6.3.1.1.2 Answering modem
+
+a) On connection to line the answering modem shall be conditioned to transmit signals in the high
+ channel at 1200 bit/s in accordance with section 2.5.2.2 and receive signals in the low channel at
+ 1200 bit/s. Following transmission of the answer sequence in accordance with Recommendation
+ V.25, the modem shall apply an ON condition to circuit 107 and then transmit unscrambled
+ binary 1 at 1200 bit/s.
+
+b) If the modem detects scrambled binary 1 or 0 in the low channel at 1200 bit/s for 270 +-40 ms,
+ the handshake shall continue in accordance with section 6.3.1.2.2 b) and c). However, if unscrambled
+ repetitive double dibit 00 and 11 at 1200 bit/s is detected in the low channel, at the end of
+ receipt of this signal the modem shall apply an ON condition to circuit 112 and then transmit
+ an unscrambled repetitive double dibit pattern of 00 and 11 at 1200 bit/s for 100 +-3 ms.
+ Following these signals the modem shall transmit scrambled binary 1 at 1200 bit/s.
+
+c) 600 +-10 ms after circuit 112 has been turned ON the modem shall begin transmitting scrambled
+ binary 1 at 2400 bit/s, and 450 +-10 ms after circuit 112 has been turned ON the receiver may
+ begin making 16-way decisions.
+
+d) Following transmission of scrambled binary 1 at 2400 bit/s for 200 +-10 ms, circuit 106 shall
+ be conditioned to respond to circuit 105 and the modem shall be ready to transmit data at
+ 2400 bit/s.
+
+e) When 32 consecutive bits of scrambled binary 1 at 2400 bit/s have been detected in the low
+ channel the modem shall be ready to receive data at 2400 bit/s and shall apply an ON
+ condition to circuit 109.
+
+6.3.1.2 Interworking at 1200 bit/s
+
+The following handshake is identical to the Recommendation V.22 alternative A and B handshake.
+
+6.3.1.2.1 Calling modem
+
+a) On connection to line the calling modem shall be conditioned to receive signals in the high
+ channel at 1200 bit/s and transmit signals in the low channel at 1200 bit/s in accordance
+ with section 2.5.2.2. It shall apply an ON condition to circuit 107 in accordance with
+ Recommendation V.25. The modem shall initially remain silent.
+
+b) After 155 +-10 ms of unscrambled binary 1 has been detected, the modem shall remain silent
+ for a further 456 +-10 ms then transmit scrambled binary 1 at 1200 bit/s (a preceding V.22 bis
+ signal, as shown in Figure 7/V.22 bis, would not affect the operation of a V.22 answer modem).
+
+c) On detection of scrambled binary 1 in the high channel at 1200 bit/s for 270 +-40 ms the modem
+ shall be ready to receive data at 1200 bit/s and shall apply an ON condition to circuit 109 and
+ an OFF condition to circuit 112.
+
+d) 765 +-10 ms after circuit 109 has been turned ON, circuit 106 shall be conditioned to respond
+ to circuit 105 and the modem shall be ready to transmit data at 1200 bit/s.
+
+6.3.1.2.2 Answering modem
+
+a) On connection to line the answering modem shall be conditioned to transmit signals in the high
+ channel at 1200 bit/s in accordance with section 2.5.2.2 and receive signals in the low channel at
+ 1200 bit/s.
+
+ Following transmission of the answer sequence in accordance with V.25 the modem shall apply
+ an ON condition to circuit 107 and then transmit unscrambled binary 1 at 1200 bit/s.
+
+b) On detection of scrambled binary 1 or 0 in the low channel at 1200 bit/s for 270 +-40 ms the
+ modem shall apply an OFF condition to circuit 112 and shall then transmit scrambled binary 1
+ at 1200 bit/s.
+
+c) After scrambled binary 1 has been transmitted at 1200 bit/s for 765 +-10 ms the modem shall be
+ ready to transmit and receive data at 1200 bit/s, shall condition circuit 106 to respond to
+ circuit 105 and shall apply an ON condition to circuit 109.
+
+Note - Manufacturers may wish to note that in certain countries, for national purposes, modems are
+ in service which emit an answering tone of 2225 Hz instead of unscrambled binary 1.

+\section adsi_tests_page_sec_1 What does it do?
+These tests exercise the ADSI module, for all supported standards. A transmit
+and a receive instance of the ADSI module are connected together. A quantity
+of messages is passed between these instances, and checked for accuracy at
+the receiver. Since the FSK modems used for this are exercised fully by other
+tests, these tests do not include line modelling.
+
+\section adsi_tests_page_sec_2 How does it work?

+These tests are fashioned after those on the CM7291 test tape from
+Mitel. Those tests are for DTMF, rather than Bell MF, but make a
+fair starting point for a set of meaningful tests of Bell MF.
+
+These tests include conversion to and from A-law. It is assumed the
+distortion this produces is comparable to u-law, so it should be
+a fair test of performance in a real PSTN channel.

+\section dtmf_rx_tests_page_sec_1 What does it do?
+
+The DTMF detection test suite performs similar tests to the Mitel test tape,
+traditionally used for testing DTMF receivers. Mitel seem to have discontinued
+this product, but all it not lost.
+
+The first side of the Mitel tape consists of a number of tone and tone+noise
+based tests. The test suite synthesizes equivalent test data. Being digitally
+generated, this data is rather more predictable than the test data on the nasty
+old stretchy cassette tapes which Mitel sold.
+
+The second side of the Mitel tape contains fragments of real speech from real
+phone calls captured from the North American telephone network. These are
+considered troublesome for DTMF detectors. A good detector is expected to
+achieve a reasonably low number of false detections on this data. Fresh clean
+copies of this seem to be unobtainable. However, Bellcore produce a much more
+aggressive set of three cassette tapes. All six side (about 30 minutes each) are
+filled with much tougher fragments of real speech from the North American
+telephone network. If you can do well in this test, nobody cares about your
+results against the Mitel test tape.
+
+A fresh set of tapes was purchased for these tests, and digitised, producing 6
+wave files of 16 bit signed PCM data, sampled at 8kHz. They were transcribed
+using a speed adjustable cassette player. The test tone at the start of the
+tapes is pretty accurate, and the new tapes should not have had much opportunity
+to stretch. It is believed these transcriptions are about as good as the source
+material permits.
+
+PLEASE NOTE
+
+These transcriptions may be freely used by anyone who has a legitimate copy of
+the original tapes. However, if you don't have a legitimate copy of those tapes,
+you also have no right to use this data. The original tapes are the copyright
+material of BellCore, and they charge over US$200 for a set. I doubt they sell
+enough copies to consider this much of a business. However, it is their data,
+and it is their right to do as they wish with it. Currently I see no indication
+they wish to give it away for free.

+of a time domain echo canceller. It shows, graphically:
+
+ - the spectrum of the received signal.
+ - the line model in use (when a known line model is being used).
+ - the adapted coefficients of the canceller.
+
+\section echo_monitor_page_sec_2 How does it work?
+This code uses the FLTK cross platform GUI toolkit. It works on X11 and Windows platforms.
+In addition to the basic FLTK toolkit, fltk_cartesian is also required.

+/*! \page fsk_tests_page FSK modem tests
+\section fsk_tests_page_sec_1 What does it do?
+These tests allow either:
+
+ - An FSK transmit modem to feed an FSK receive modem, of the same type,
+ through a telephone line model. BER testing is then used to evaluate
+ performance under various line conditions. This is effective for testing
+ the basic performance of the receive modem. It is also the only test mode
+ provided for evaluating the transmit modem.
+
+ - An FSK receive modem is used to decode FSK audio, stored in a wave file.
+ This is good way to evaluate performance with audio recorded from other
+ models of modem, and with real world problematic telephone lines.
+

+\section g722_tests_page_sec_1 What does it do?
+This modules implements two sets of tests:
+ - The tests defined in the G.722 specification, using the test data files supplied
+ with the specification.
+ - A generally audio quality test, consisting of compressing and decompressing a speeech
+ file for audible comparison.
+
+The speech file should be recorded at 16 bits/sample, 16000 samples/second, and named
+"pre_g722.wav".
+
+The ITU tests use the codec in a special mode, in which the QMFs, which split and recombine the
+sub-bands, are disabled. This means they do not test 100% of the codec. This is the reason for
+including the additional listening test.
+
+\section g722_tests_page_sec_2 How is it used?
+To perform the tests in the G.722 specification you need to obtain the test data files from the
+specification. These are copyright material, and so cannot be distributed with this test software.
+
+The files, containing test vectors, which are supplied with the G.722 specification, should be
+copied to itutests/g722. The ITU tests can then be run by executing g722_tests without
+any parameters.
+
+To perform a general audio quality test, g722_tests should be run with a parameter specifying
+the required bit rate for compression. The valid parameters are "-48", "-56", and "-64".
+The file ../test-data/local/short_wb_voice.wav will be compressed to the specified bit rate, decompressed,
+and the resulting audio stored in post_g722.wav.

+
+The files, containing test vectors, which are supplied with the G.726 specification, should be
+copied to itutests/g726 so the files are arranged in the same directory heirarchy in which they
+are supplied. That is, you should have file names like

+ - itutests/g726/DISK2/INPUT/NRM.A
+ - itutests/g726/DISK2/INPUT/OVR.A
+
+in your source tree. The ITU tests can then be run by executing g726_tests without
+any parameters.
+
+To perform a general audio quality test, g726_tests should be run with a parameter specifying
+the required bit rate for compression. The valid parameters are "-16", "-24", "-32", and "-40".
+The test file ../test-data/local/short_nb_voice.wav will be compressed to the specified bit rate,
+decompressed, and the resulting audio stored in post_g726.wav.

+/*! \page gsm0610_tests_page GSM 06.10 full rate codec tests
+\section gsm0610_tests_page_sec_1 What does it do?
+Two sets of tests are performed:
+ - The tests defined in the GSM 06.10 specification, using the test data files supplied with
+ the specification.
+ - A generally audio quality test, consisting of compressing and decompressing a speeech
+ file for audible comparison.
+
+The speech file should be recorded at 16 bits/sample, 8000 samples/second, and named
+"pre_gsm0610.wav".
+
+\section gsm0610_tests_page_sec_2 How is it used?
+To perform the tests in the GSM 06.10 specification you need to obtain the test data files from the
+specification. These are copyright material, and so cannot be distributed with this test software.
+They can, however, be freely downloaded from the ETSI web site.
+
+The files, containing test vectors, which are supplied with the GSM 06.10 specification, should be
+copied to etsitests/gsm0610/unpacked so the files are arranged in the following directories.

+This is different from the directory structure in which they are supplied. Also, the files names are a little
+different. The supplied names are messy, and inconsistent across the sets. The names required by these tests
+just clean up these inconsistencies. Note that you will need a Windows machine to unpack some of the supplied
+files.
+
+To perform a general audio quality test, gsm0610_tests should be run. The file ../test-data/local/short_nb_voice.wav
+will be compressed to GSM 06.10 data, decompressed, and the resulting audio stored in post_gsm0610.wav.

+To perform a general audio quality test, ima_adpcm_tests should be run. The test file
+../test-data/local/short_nb_voice.wav will be compressed to the specified bit rate,
+decompressed, and the resulting audio stored in post_ima_adpcm.wav. A simple SNR test
+is automatically performed. Listening tests may be used for a more detailed evaluation
+of the degradation in quality caused by the compression.

+
+ - the spectrum of the received signal.
+ - the line model in use (when a known line model is being used).
+ - the adapted coefficients of the canceller.
+
+\section line_model_monitor_page_sec_2 How does it work?
+This code uses the FLTK cross platform GUI toolkit. It works on X11 and Windows platforms.

+/*! \page modem_echo_can_tests_page Line echo cancellation for modems tests
+\section modem_echo_can_tests_page_sec_1 What does it do?
+Currently the echo cancellation tests only provide simple exercising of the
+cancellor in the way it might be used for line echo cancellation. The test code
+is in echotests.c.
+
+The goal is to test the echo cancellor again the G.16X specs. Clearly, that also
+means the goal for the cancellor itself is to comply with those specs. Right
+now, the only aspect of these tests implemented is the line impulse response
+models in g168tests.c.
+
+\section modem_echo_can_tests_page_sec_2 How does it work?
+The current test consists of feeding a wave file of real speech to the echo
+cancellor as the transmit signal. A very simple model of a telephone line is
+used to simulate a simple echo from the transmit signal. A second wave file of
+real speech is also used to simulate a signal received form the far end of the
+line. This is gated so it is only placed for one second every 10 seconds,
+simulating the double talk condition. The resulting echo cancelled signal can
+either be store in a file for further analysis, or played back as the data is
+processed.
+
+A number of modified versions of this test have been performed. The signal level
+of the two speech sources has been varied. Several simple models of the
+telephone line have been used. Although the current cancellor design has known
+limitations, it seems stable for all these test conditions. No instability has
+been observed in the current version due to arithmetic overflow when the speech
+is very loud (with earlier versions, well, ....:) ). The lack of saturating
+arithmetic in general purpose CPUs is a huge disadvantage here, as software
+saturation logic would cause a major slow down. Floating point would be good,
+but is not usable in the Linux kernel. Anyway, the bottom line seems to be the
+current design is genuinely useful, if imperfect.
+
+\section modem_echo_can_tests_page_sec_2 How do I use it?
+
+Build the tests with the command "./build". Currently there is no proper make
+setup, or way to build individual tests. "./build" will built all the tests
+which currently exist for the DSP functions. The echo cancellation test assumes
+there are two wave files containing mono, 16 bit signed PCM speech data, sampled
+at 8kHz. These should be called local_sound.wav and far_sound.wav. A third wave
+file will be produced. This very crudely starts with the first 256 bytes from
+the local_sound.wav file, followed by the results of the echo cancellation. The
+resulting audio is also played to the /dev/dsp device. A printf near the end of
+echo_tests.c is commented out with a \#if. If this is enabled, detailed
+information about the results of the echo cancellation will be written to
+stdout. By saving this into a file, Grace (recommended), GnuPlot, or some other
+plotting package may be used to graphically display the functioning of the
+cancellor.

+of a modem. It shows, graphically:
+
+ - the constellation, for PSK, QAM and other similar modulations.
+ - the equalizer status, for modems with adaptive equalizers.
+ - the carrier frequency.
+ - the symbol timing correction.
+
+\section constel_page_sec_2 How does it work?
+This code uses the FLTK cross platform GUI toolkit. It works on X11 and Windows platforms.
+In addition to the basic FLTK toolkit, fltk_cartesian is also required.

+../test-data/local/short_nb_voice.wav will be compressed to the specified bit rate,
+decompressed, and the resulting audio stored in post_oki_adpcm.wav. A simple SNR test
+is automatically performed. Listening tests may be used for a more detailed evaluation
+of the degradation in quality caused by the compression. Both 32k bps and 24k bps
+compression may be tested.

+These tests are fashioned after those on the CM7291 test tape from
+Mitel. Those tests are for DTMF, rather than R2 MF, but make a
+fair starting point for a set of meaningful tests of R2 MF.
+
+These tests include conversion to and from A-law. It is assumed the
+distortion this produces is comparable to u-law, so it should be
+a fair test of performance in a real PSTN channel.

+/*! \page v17_tests_page V.17 modem tests
+\section v17_tests_page_sec_1 What does it do?
+These tests test one way paths, as V.17 is a half-duplex modem. They allow either:
+
+ - A V.17 transmit modem to feed a V.17 receive modem through a telephone line
+ model. BER testing is then used to evaluate performance under various line
+ conditions. This is effective for testing the basic performance of the
+ receive modem. It is also the only test mode provided for evaluating the
+ transmit modem.
+
+ - A V.17 receive modem is used to decode V.17 audio, stored in a wave file.
+ This is good way to evaluate performance with audio recorded from other
+ models of modem, and with real world problematic telephone lines.
+
+If the appropriate GUI environment exists, the tests are built such that a visual
+display of modem status is maintained.
+
