Systems Equipped With Cross-Connect Option
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 two WANs.
Refer to Table 28 for detailed information.
