We have never really experienced any PCM Upstream with anything, but that's expected if nearly zero client modems support it. We also had a Patton and sent it back. It was SLOW, and no PCM Upstream with anything we tried. The only client modem we've seen that says it supports PMC and has software to control it is USR's Performance Pro modem. However, the old firmware didn't really do it, and the new firmware breaks the modem permanently so that nothing works at all, and of course, there's no way to go back to an older firmware, so it get's pretty expensive, pretty quickly. :-) ----- Original Message ----- From: Joel - Fox Computers To: usr-tc@mailman.xmission.com Sent: Tuesday, March 11, 2003 10:39 PM Subject: [USR-TC] V.92 / TCS 4.7 Question Full of questions tonight :-) Just noticed the following on modemsite.com: 15-Nov-02 - 3Com/Commworks releases improved V.92 code. TCS Release 4.7 was made available on 13-Nov at Commworks' Total Control site for the TC1000 RAS. Commworks indicates this release will support PCM upstream rates as high as 36,000bps. (The only other RAS vendor that includes PCM upstream support at this time is Patton.) In addition, the new Commworks code includes improved V.92 support that will help with GSTN cleardown, retrain, and rate-shift problems. Does TCS 4.7 make a difference with V.92 that customer might notice? Or were the same improvements made in the latest update to TCS 4.5? I was under the impression that 4.7 didn't make a big difference as far as how it handles V.92. But if that's not the case I'd really like to know. Thanks, Joel
