I'm trying to convert from Asterisk to Freeswitch, and have a question about spans.
I read the freetdm configuration example for TDM400 and am wondering what exactly is a span.
I have 2 TDM400P cards in my computer, one card has 2 FXS modules for connecting analog phones. The other card has 3 FXO modules for connecting to 3 PSTN trunk lines.
# lsdahdi ### Span 1: WCTDM/4 "Wildcard TDM400P REV I Board 5" 1 FXS FXOKS (In use) (EC: OSLEC - INACTIVE) 2 FXS FXOKS (In use) (EC: OSLEC - INACTIVE) 3 unknown Reserved 4 unknown Reserved ### Span 2: WCTDM/4 "Wildcard TDM400P REV I Board 5" (MASTER) 5 FXO FXSKS (In use) (EC: OSLEC - INACTIVE) 6 FXO FXSKS (In use) (EC: OSLEC - INACTIVE) 7 FXO FXSKS (In use) (EC: OSLEC - INACTIVE) 8 unknown Reserved
Do I configure freetdm as in the example for TDM400 with separate spans for each module like the following? or should I have just two spans as shown by lsdahsi? Thanks.
Hi Jeremy
Do you find the answer to this question?
I'm also very confuse on the span and channel in both asterisk and freeswitch, and I've found little explaination on this.
" A span is a logical unit that represents a group of channels. With digital telephony, a span usually represents a physical port on the card. If the system has only one such card with a single port, so it is referred to as span 1. "
Could anyone help on this?
At the very least you need 2 freetdm span configurations because you cannot mix FXS and FXO channels in the same FreeTDM logical span. http://wiki.freeswitch.org/wiki/FreeTDM#DAHDI_mode For the given hardware output, I'd simply create 2 spans, one for all the fxo channels and one for all the fxs channels. *Moises Silva **Manager, Software Engineering*** msilva@sangoma.com Sangoma Technologies 100 Renfrew Drive, Suite 100, Markham, ON L3R 9R6 Canada t. +1 800 388 2475 (N.
