This register controls the insertion of tributary path defect indications (PDI) on the
receive alarm port (RAD) as a result of tributary pointer alarms, tributary
unequipped alarms, and tributary path defect indication alarms.
PDIVPDI:
The PDIVPDI bit is an active high path PDI insertion enable. When PDIVPDI
is set high, PDI-P is reported on RAD when tributary path defect indication is
detected in the tributary path signal label of the associated incoming tributary.
When PDIVPDI is set low, reporting of path PDI due to PDI-V is inhibited.
UNEQPDI:
The UNEQPDI bit is an active high path PDI insertion enable. When
UNEQPDI is set high, PDI-P is reported on RAD when tributary unequipped
indication ('b000) is detected in the tributary path signal label of the
associated incoming tributary. When UNEQPDI is set low, reporting of path
PDI due to UNEQ is inhibited.
AISPDI:
The AISPDI bit is an active high path PDI insertion enable. When AISPDI is
set high, PDI-P is reported on RAD when the associated incoming tributary is
in AIS state. When AISPDI is set low, reporting of path PDI due to AIS is
inhibited.
