If I understand the connection correctly the routers are either using SDLC 
Relay (Simply passing
every SDLC frame in a TCP Packet) or Data Link Switching (Passing only usefull 
frames in TCP Packets
and spoofing the others).  It sounds more like SDLC Relay because of the 
timeouts.  You should avoid
SDLC relay if at all possible and use DLSw.
