Anyhow, if you have data grade phone lines, the phone company usually
will gaurantee (whatever thats worth), that the line will carry data
at 9600 baud. Anything over that, and you're pretty much on your
own, however, I've found that most data grade phone lines are pretty
good. However, if you are using a centrex service, I've heard of
excess line noise being generated by the centrex PBX. Here again,
less throughput.
All in all, they are basically making sure that your modems can work
with the way they phone lines are "built". If the phone line is
built to spec at 9600 baud (which is the limit of their gaurantee),
but your modem requires a better connection, you are pretty much out
of luck. Some phone companies will help you fix the problem, but you
will end up paying for anything that exceeds the minimum that they
gaurantee.

I am using a pm2e with penril modems!!! My phone company contacted me
today and wanted me to give them the specifications that we require
fromthe phones lines to help this resolve this problem. Things like S/N
ratio, attenuations etc. I am not sure what other factors they
requireand what ranges these should be.
