This register controls the auto assertion of enhanced path RDI (G1 bit 5, 6 and 7) in the TPOP for
the entire SONET/SDH stream.
NOLOPCONEPRDI:
When set high, the NOLOPCONEPRDI bit disables enhanced path RDI assertion when loss
of pointer concatenation (LOPCON) events are detected in the receive stream. When
NOLOPCONEPRDI is set high and LOPCON occurs, bit 6 of the G1 byte is set low while bit 7
of the G1 byte is set high. NOLOPCONEPRDI has precedence over PSLMERDI, TIMEPRDI
and UNEQERDI.
When NOLOPCONEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI,
TIMEPRDI and UNEQERDI and the associated alarm states.
NOLOPEPRDI:
When set high, the NOLOPEPRDI bit disables enhanced path RDI assertion when loss of
pointer (LOP) events are detected in the receive stream. When NOLOPEPRDI is set high
and LOP occurs, bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set high.
NOLOPEPRDI has precedence over PSLMERDI, TIMEPRDI and UNEQERDI.
When NOLOPEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI,
TIMEPRDI and UNEQERDI and the associated alarm states.
NOPAISEPRDI:
When set high, the NOPAISEPRDI bit disables enhanced path RDI assertion when the path
alarm indication signal state (PAIS) is detected in the receive stream. When NOPAISEPRDI
is set high and PAIS occurs, bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set
high. NOPAISEPRDI has precedence over PSLMERDI, TIMEPRDI and UNEQERDI.
