I don't know much on them, but perhaps the Adtran Atlas line of products might be able to help. I know they can do voice and data PRI's, along with ISDN, but beyond that, I am without experience. :(
Just thought I'd throw that out as an option. -Mark -----Original Message----- From: Howard C. Berkowitz [mailto:[EMAIL PROTECTED] Sent: Thursday, March 06, 2003 11:45 AM To: [EMAIL PROTECTED] Subject: ISDN switch (beyond simulator) [7:64628] We've all dealt with ISDN simulators, that look like a CO to a single or small set of interfaces. I'm dealing with a situation where I need to interconnect several simulated training sites (i.e., physically in the same room) and telephony servers through a PSTN simulation. In other words, I need a small CO switch, with the ability at least to interconnect several trunks (probably both T1 E&M and ISDN PRI), with a static calling plan among tens of telephones. The switch would emulate several end offices, plus the PSTN interoffice connectivity between them. For the latter, however, I don't need to have physical interoffice trunks as long as I can simulate their effect in a dialing plan. The switch should also be able to simulate dedicated data links between sites. In the real world, this is no problem to do with off-the-shelf equipment that would support thousands of lines. Within the Cisco product line, I suspect I get close with an MGX or the like, but probably fall short in circuit-switch call supervision and routing. Thoughts? I'm going to review my Nortel Passport documents to see if it has the loop supervision capabilities available; I vaguely remember a version that might.
