Fault signaling out-of-service type A or B codes are used by tandem nodes to notify
remote circuits of link failures.
Out-of-service type A signaling is an all ones signal.
Out-of-service type B signaling (0110) can be used if an all ones signal cannot be
used, for example, when an all ones signal has meaning for the cross-connected
circuit.
Out-of-service type C signaling generates a yellow alarm on the DS1 circuit.
If fault signaling is turned off for any E1 circuit, trunk conditioning is not applied to
that circuit, regardless of how it is configured for the link. That is, the circuit
connected to the link stays connected during any red or yellow alarms. Trunk
conditioning is described in section 15.6.
