This register controls the auto assertion of path RDI (G1 bit 5) in the TPOP for the entire
SONET/SDH stream. Also see the 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 high, the transmit line RDI will be inserted. When LOPCONPRDI is set
low, no action is taken. This register bit is used only if the AUTOPRDI register bit is also set
high.
LOPPRDI:
The Loss of Pointer Indication PRDI (LOPPRDI) controls the insertion of a Path RDI in the
transmit data stream upon detection of this alarm condition. When LOPPRDI is set high, the
transmit line RDI will be inserted. When LOPPRDI is set low, no action is taken. This register
bit is used only if the AUTOPRDI register bit is also set high.
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 high, the
transmit line RDI will be inserted. When PAISPRDI is set low, no action is taken. This
register bit is used only if the AUTOPRDI register bit is also set high.
ALRMPRDI:
The Line Alarm Indication Signal PRDI (ALRMPRDI) controls the insertion of a Path RDI in
the transmit data stream upon detection of one of the following alarm conditions: Loss of
Signal (LOS), Loss of Frame (LOF) and Line Alarm Indication Signal (LAIS). When
