56K modem technology requires a digital trunk on one side on the link. I
don't know any individuals who have a T1 out to their house, so that
responsibility falls on the ISP. ;-) So I guess if you want to use a PM2,
you better find a modem rack that terminates 56K modems on the WAN side
(via T1/PRI), and has RS232 ports on the back-side. For a better
explanation on what is require at the ISP premise try our web at
