PSLMAIS:
When set high, the PSLMAIS bit enables path AIS and DS3 AIS insertion on
the DROP bus when path signal label mismatch (PSLM) events are detected
in the receive stream. When PSLMAIS is set low, path signal label mismatch
events have no effect on the DROP bus.
NOTE: This register bit should only be used when the RPPS is configured as
a master. Otherwise, it should normally be set low. The register bit will also
force the associated slaves RPPS’s to insert path AIS.
PSLUAIS:
When set high, the PSLUAIS bit enables path AIS and DS3 AIS insertion on
the DROP bus when path signal label unstable (PSLU) events are detected in
the receive stream. When PSLUAIS is set low, path signal label unstable
events have no effect on the DROP bus.
NOTE: This register bit should only be used when the RPPS is configured as
a master. Otherwise, it should normally be set low. The register bit will also
force the associated slaves RPPS’s to insert path AIS.
UNEQAIS:
When set high, the UNEQAIS bit enables path AIS and DS3 AIS insertion on
the DROP bus when path signal label in the receive stream indicates
unequipped status (UNEQ). When UNEQAIS is set low, the path signal label
unequipped status has no effect on the DROP bus.
NOTE: This register bit should only be used when the RPPS is configured as
a master. Otherwise, it should normally be set low. The register bit will also
force the associated slaves RPPS’s to insert path AIS.
