You didn't say what protocol you wanted to use but.......this solution
IS expensive but works.

AT&T makes a packet data switch called ISN (information System Network).
An ISN node would be installed at one host end and a wire concentrator at
the other host using either DDS or analog dedicated service between
(9.6, 56k or T1). If you want to transfer ethernet, you plug EBIM (ether-
net Bridge Interface Moduals) between each end and transport RFS over ether-
net. If it's AT&T's 3bs your using, you could RFS over StarLan
hardware and use SLIMB cards (StarLan Interface Modual - Bridge) in the
ISN and transport RFS over the ISN. But be warned - it ain't cheep!!!
