LOPDS3AIS:
When set high, the LOPDS3AIS bit enables DS3 AIS assertion when loss of
pointer (LOP) events are detected in the receive stream. When LOPDS3AIS
is set low, loss of pointer events have no effect on DS3 AIS.
PSLMDS3AIS:
When set high, the PSLMDS3AIS bit enables DS3 AIS assertion when path
signal label mismatch (PSLM) events are detected in the receive stream.
When PSLMDS3AIS is set low, path signal label mismatch events have no
effect on DS3 AIS.
PSLUDS3AIS:
When set high, the PSLUDS3AIS bit enables DS3 AIS assertion when path
signal label unstable (PSLU) events are detected in the receive stream.
When PSLUDS3AIS is set low, path signal label unstable events have no
effect on DS3 AIS .
ALMAIS:
When set high, the ALMAIS bit enables path AIS and DS3 AIS assertion
when loss of signal (LOS), loss of frame (LOF) or line alarm indication signal
(LAIS) events are detected in the receive stream. When ALMAIS is set low,
the above events have no effect on path AIS nor DS3 AIS.
