As we outgrow our KX-T1232, we are looking for a new PBX. Of course we want all the normal PBX features like ARS and DID; what we want that is a bit unusual is the ability to have station lines that are ground start or at least provide a CPC signal (a momentary open) when the calling party hangs up. The only switch that I have personally witnessed this on was a NEC NEAX 2400. The analog ports on the NEC received CPC. However, a friend reports that he checked another NEAX 2400 and found that not to be the case. Perhaps there are several varieties of analog station cards. I would appreciate hearing from anyone that knows of a switch that does what we want. Thanks...

The analog ports on the NEC received CPC. Wow, this is a tough one. Most XBAR and SXS systems had this, of course. Even 101ESS Centrex CU appliques had it. But on a modern electronic PBX in the 100 line range? If you were big enough, you could get the PBX version of the 5ESS or DMS-100 (SL-100), and they could be equipped with the right station cards to do it... The only system I know of that might have it (definite maybe here) is Redcom. As a manufacturer of small CO's, you might be able to fit their system with the right kind of line cards, if the software could handle it. You might ask National Telecom / Solid State Systems (in Atlanta) if their Jr. Exec or other switch could do it. These systems are somewhat specialized.... There's a lot of similarity between some of the Northern Telecom systems and their small CO's....but you'll have to talk to their engineering people to confirm this. A hint: If the switch can be fitted to provide answer supervsion (reverse battery) on the ports, then it's probably going to do the job. Wanna buy an old OKI 200 line crossbar switch? I'm pulling one out in January from a hotel... Macy M.

The AT&T System 25 provides a 500 msec open loop on its Tip & Ring station lines when a call is disconnected. I don't know any way of getting ground-start station lines, but CPC is definitely available. Dave Levenson Voice: (201) 647 0900 Westmark, Inc.
