Nope.  As another poster pointed out, there is a register that
controls this, and when properly set, the T2500 can answer PEP or
V.32 calls.  We have a dialup V.32 that is used for incoming calls
where the remote modems are USR Duals or other Telebits (T2500s and 
Trailblazer Plus), and it all works fine: V.32 connections for the
modems with V.32 and PEP connections for the Trailblazers.  As for
the T2500s, it is up to the originating user (software) to decide
whether to use PEP or V.32.  For interactive stuff we use V.32 on
those modems.

Also, I believe that your uucp neighbor, uunet, uses T2500s nowadays,
for V.32 and PEP connections.
