Well, we use (rented) AT&T Dataphone II modems. They run at 9.6 and (I
think now) 14.4. Not the fastest possible (Codex and Paradyne have
those records) but good enough for us and it sure is great having the
long lines vendor be the customer equipment vendor. No finger
pointing. (We also have their network monitor which does line quality
evaluation. It provides both hardcopy and a dial in port for the AT&T
diagnostic center.) We get a lot of cooperation from AT&T when we
complain about line errors. I don't know how much is due to using AT&T
modems but it can't hurt. 

If you're using DDS, AT&T has *the best* DSU/CSUs I've seen. It also
ties into their network monitor.
