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.
