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!
