 Once when I was working at the U. of Chicago, I was assigned a job
of setting up a connection to outside for database search. So I bought a
modem in hoping that I could dial out to Compuserve and connect to the
database vendor through Compuserve. To my surprise, I could not dial out.
Since it was a brand new modem, I didn't suspect it to be the culprit. So I
called the telecommunication department and was told that the telephone
line the modem connected to was a digital line and modem would not work on
a digital line. The person on the other end of the line suggested me a
piece of equipment which would work on a digital line just the same as a
modem would work on an analogue line.

 My question is: does anybody know what the name of the equipment is? How
does it differ from a modem in terms of signal processing? 

Thanks in advance for any reply.
