I guess this could all revolve around phone line quality and what you expect on interactive dialups. I routinely use my T1000 interactively into a bank of rackmount T2500's and have absolutely not gripes whatsoever as to throughput. No, it isn't true 9600, but I can't read that fast anyway so BFD! On news feeds with UUCP the T1000 will hands down blow away ANY V.32 I have ever seen, and this statement is made after one modem vendor spent 3 weeks trying to get V.32 to even come close and gave up! This entailed new firmware, setup changes, line testing etc. We also evaluated 3 other vendors and found no significant differences. 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! The bottom line here (to summarize my ramblings) is simple: V.32 works great under "ideal conditions", but stinks in my version of "reality". I have never seen PEP fail to anywhere under any conditions if the phone co can connect 'em. It may train down slower that full speed, but it WILL get you there! What I recommend? The Telebit T2500 defaulting to PEP. This way the folks who call in wanting V.32 connections can get 'em, news and mail travel PEP to minimize phone charges, and outward V.32 connections can be configured for sites that won't talk to anything else. Regarding the T1000, I think it is an excellent product and personally own one. I find the interactive throughput on my T1000 to actually be faster than on the TB+ ot T2500. -- ================================================================================ Tim Dawson (tim@dal.fsd.mot.com) Unix Systems and Networking Administrator Motorola Computer Systems - MIS Bellnet: (214)-888-2231 1701 Valley View Lane, Farmers Branch TX. 75234
