Summary: Correction to my posting


>Trailblazer...uses Trellis coding.

Several people have been kind enough to explain that the multiple
carrier PEP transmission mode of the Trailblazer should not be
equated to Trellis modulation used in v.29 modems.  Sorry if my
incorrect statment caused any confusion.

Apparently a major benefit (which I did correctly state) of the
Trailblzer's FAST mode is that fallback can be in quite small
baudrate increments, unlike v.29 modems that have to fall back by
factors of 2.
