I had responded privately to the original posting, but seeing this
response I think I'll post publicly now.  PSINet operates V.32 dialups
throughout the US, with a cast of LEC's providing the service from
PACBell, to NETEL, to Rochester Telephone, etc..  The T2500 in V.32
mode DOES appear to us to be succeptible to line noise.  We've had
problems.

In PEP mode (only good for UUCP these days it would appear) there isn't
a problem.

What PC Week reported was on V.32 performance, and it was no surprise
to us.
