System with Cross-Connect Option
14.4.1 Circuit Diagnostics
In systems equipped with Cross-Connect CPUs, the cross-connect element adds another level
of testing within the node and enhances the system’s diagnostic capabilities. The operator may
also monitor and set the state of the Transmit and Receive ABCD signaling bits of a digitized
voice circuit that is cross-connected between WANs. The table below shows detailed
information on the diagnostic capabilities of the circuits.
