14.3 User port Diagnostics

14.3.1 WAN Diagnostics

Software-initiated diagnostics on T1 WAN aggregates involve looping the WAN signal
toward the network (line loopback) or the system (local loopback) and placing any one of the
DS0 channels that make up the WAN signal in local loopback. The table below list detailed
information on the diagnostic capabilities of the WAN ports.
