This register controls the auto assertion of line RDI in the local TLOP. Since the
S/UNI-QUAD provides STS-3c (STM-1/AU4) mappings, this register controls the
assertion of line RDI for the entire SONET/SDH stream.
LAISLRDI:
The Line Alarm Indication Signal LRDI (LAISLRDI) controls the insertion of a
Line RDI in the transmit data stream upon detection of this alarm condition.
When LAISLRDI is set to logic one, the transmit line RDI will be inserted.
When LAISLRDI is set to logic zero, no action is taken. This register bit has
effect only if the AUTOLRDI register bit is also set to logic one.
LOSLRDI:
The Loss of Signal LRDI (LOSLRDI) controls the insertion of a Line RDI in the
transmit data stream upon detection of this alarm condition. When LOSLRDI
is set to logic one, the transmit line RDI will be inserted. When LOSLRDI is set
to logic zero, no action is taken. This register bit has effect only if the
AUTOLRDI register bit is also set to logic one.
LOFLRDI:
The Loss of Frame LRDI (LOFLRDI) controls the insertion of a Line RDI in the
transmit data stream upon detection of this alarm condition. When LOFLRDI
is set to logic one, the transmit line RDI will be inserted. When LOFLRDI is set
to logic zero, no action is taken. This register bit has effect only if the
AUTOLRDI register bit is also set to logic one.
SFLRDI:
The Signal Fail BER LRDI (SFLRDI) controls the insertion of a Line RDI in the
transmit data stream upon detection of this alarm condition. When SFLRDI is
set to logic one, the transmit line RDI will be inserted. When SFLRDI is set to
