Easily since all the sites I'm interested in calling have Telebits.  Some also
have V.32.

The nice thing about standards is that there are so many to choose from
(Tanenbaum).  A standard like V.32 that can't maintain a connection over less
than perfect lines is useless to me.  Two immediate examples are the neighboring
GTE service area and international calls.  Three kinds of V.32 modems could not
maintain a connection from either to UIUC while the telebits ran w.o. problem.

I will take the best available that fits my needs.  V.32 is a bad standard
in my book given its performance losses.  Handling noisy or sub-standard
lines by dropping back to 4800 or 2400 baud is hardly what I would call 
robust.

>The T2500 fits all of these requirements, but is too expensive.

Modems that can't perform are even more expensive.
