Digital circuits are not so easy to tap into as opposed to POTS.<br><br>I'm thinking about this issue because I'm wondering how the US Govt. sets their DRSN lines up to be secure. From what I read, only Raytheon and Telecore have DRSN-use JITC-approved switches. It seems that list may be old since I've heard that they're now running a 50k device DRSN network with Cisco gear/software. I suppose for their hardware switches, they must be installing some really long haul trunks from end to end around the world for security.<br><br>Thanks Brian.<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><font size="2" face="Tahoma"><hr size="1"><b><span

I'm assuming if there's any POTS/BRI/PRI/DSS circuits used in transit, anyone with a lineman's handset could still eavesdrop on any conversations.
