A Telebit representative told me that the T2500 uses the Rockwell chip set for V.32, but the T1600 uses DSP for V.32. I thought that I read that all of Telebit's modems use DSP for V.32. Perhaps I only (wrongly) infered it from something I read here. In any case, this is the information I got from Paul Bakewell, a Telebit representative in L.A. -- favourite oxymorons: student athlete, military justice, mercy killing Ken Hendrickson N8DGN/6 kjh@usc.edu ...!uunet!usc!pollux!kjh

Apparently Telebit originally thought they could do V.32 with the DSP they used in the Trailblazers modems. Either the processor didn't have enough oomph, or their programmers didn't and they ended up kludging a little auxilliary PCB into the T2500 that used the Rockwell V.32 chipset to handle the V.32 part of the job. I guess with the T1600, they finally got at least part of their act together, assuming the result is satisfactory! -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)

It is true, the T2500 and T1500 modems are Rockwell chipset based V.32 implementations. This was the only way to bring product to market fast enough to compete with the other V.32 modems which had a head start on Telebit way back in 1988. A DSP solution was desired all the time and finally came to light in the T1600. Now we have to wait and see when Telebit decides to put PEP and V.32/V.32bis on the same DSP engine, as someone on the net called it "a T2600"?! I'm glad Paul Bakewell gave you the straight scoop, I used to work for him at Telebit. Hope this helps. =============================================================================== Cerafin E.
