Configuring WAN Line Services
2-12 117021-A Rev. A
Conventional addressing designates routers A, B, and C as DCE (address = 01)
and routers X, Y, and Z as DTE (address = 03). If router A transmits a frame
across the virtual point-to-point circuit to X, X (the intended recipient), Y, and Z
all monitor the satellite broadcast. Because X, Y, and Z all perceive a properly
addressed frame, all three accept delivery and attempt to process the frame
contents, with unpredictable results.
To avoid such confusion, assign unique addresses to each end of a point-to-point
circuit using the Local Address and Remote Address parameters. Be sure to
reverse the local and remote addresses when you configure the other end of the
point-to-point circuit.
Local Address
The local interface receives only frames whose HDLC addresses match the Local
Address parameter.
Remote Address
The router uses the Remote Address as the HDLC address for all frames
transmitted by this interface.
Viewing the Configured WAN Protocol
You can view which WAN protocol is enabled on a synchronous circuit. However,
do not change the current value.

Site Manager: Remote Address parameter: page A-49
Caution: Changing the WAN protocol does not reconfigure the interface, and
could disable it.
