This register controls the auto assertion of path RDI (G1 bit 5) in the local TPOP.
Since the S/UNI-QUAD provides STS-3c (STM-1/AU4) mappings, this register
controls the assertion of path RDI for the entire SONET/SDH stream. See also
the S/UNI-QUAD Channel Auto Enhanced Path RDI register.
LOPCONPRDI:
The Loss of Pointer Concatenation Indication PRDI (LOPCONPRDI) controls
the insertion of a Path RDI in the transmit data stream upon detection of this
alarm condition. When LOPCONPRDI is set to logic one, the transmit line RDI
will be inserted. When LOPCONPRDI is set to logic zero, no action is taken.
This register bit has effect only if the AUTOPRDI register bit is also set to logic
one.
LOPPRDI:
The Loss of Pointer PRDI (LOPPRDI) controls the insertion of a Path RDI in
the transmit data stream upon detection of this alarm condition. When
LOPPRDI is set to logic one, the transmit line RDI will be inserted. When
LOPPRDI is set to logic zero, no action is taken. This register bit has effect
only if the AUTOPRDI register bit is also set to logic one.
PAISPRDI:
The Path Alarm Indication Signal PRDI (PAISPRDI) controls the insertion of a
Path RDI in the transmit data stream upon detection of this alarm condition.
When PAISPRDI is set to logic one, the transmit line RDI will be inserted.
When PAISPRDI is set to logic zero, no action is taken. This register bit has
effect only if the AUTOPRDI register bit is also set to logic one.
