TIUAIS
This register controls the insertion of tributary path AIS as a result of tributary
path signal label alarms, tributary trace identifier alarms and tributary multiframe
alarms.
TIUAIS:
The TIUAIS bit is an active high AIS insertion enable. When TIUAIS is set
high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in trace identifier unstable state. When TIUAIS is set low,
the generation of AIS on the outgoing data stream is inhibited. The negation
of AIS occurs at tributary multiframe boundaries.
TIMAIS:
The TIMAIS bit is an active high AIS insertion enable. When TIMAIS is set
high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in trace identifier mismatch state. When TIMAIS is set low,
the generation of AIS on the outgoing data stream is inhibited. The negation
of AIS occurs at tributary multiframe boundaries.
PSLUAIS:
The PSLUAIS bit is an active high AIS insertion enable. When PSLUAIS is set
high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in path signal label unstable state. When PSLUAIS is set
