depending on where you are, there are a lot of telco's that will resell
their access.  (even uunet).  bell south for example resells their 56k
dialups for 14.95/mo to small isp's that want to support their dialup
customers, but don't want to spend $50k on an ascend max to plug in a PRI.

that's what i would do, call the telco in your area and see if they have any

Ahh.  The ISP in question has a 128K frame relay line, but that would be
a drop in the bucket.  So he has to go buy the service from the telco?
Or he has to have a T1 from the telco, those are the alternatives?
