I don't know what you get with the T1000 doing uucp, but we are getting around 1050 cps doing uucp for v.32, and around 1650 doing v.32bis --- Of course the T2000 runs around 1420 cps -- my understanding the T1000 will do around 850 at best - in which case a v.32bis is a much better selection. >The other problem I have with V.32 (and why I refuse to use it unless there >is absolutely no other alternative) is that I have been unable to get >them to hold connections for more than about 10 minutes on some of the long >distance connections that I routinely make, and V.32 won't talk all of 100 >feet through my PBX (Rolm), so if I want to use V.32 I gotta get special >phone lines to boot. Telebits - no problem, tastes great, less filling! we are now feeding several sites via both v.32 and v.32bis without problems - all of which are long distance... Maybe you are using poor quality v.32 modems? With the US Robotics v.32bis modems - we haven't a problem... >V.32 works great under "ideal conditions", but stinks in my version of >"reality". maybe with some vendor's modems - but not with the USR modems -- Larry Snyder, NSTAR Public Access Unix 219-289-0287/317-251-7391 HST/PEP/V.32/v.32bis/v.42bis regional UUCP mapping coordinator {larry@nstar.rn.com, ..!uunet!nstar.rn.com!larry}
