SDLC Support Through the XCA
XCA was primarily designed to support LAN based nodes. The FEP-4600 also supports
SDLC-attached PU 2.0 nodes by making them appear to be LAN attached. A virtual
MAC address is assigned to the SDLC device in the FEP-4600 configuration (through a
gateway circuit) and assigned to one of the network adapters. All traffic destined to the
virtual address is diverted to the associated gateway circuit that in turn sends the traffic
down the proper SDLC line.
