When NOLOPCONEPRDI is set low, reporting of enhanced RDI is according to
PSLMEPRDI , TIUEPRDI, TIMEPRDI and UNEQEPRDI 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 PSLMEPRDI , TIUEPRDI, TIMEPRDI and
UNEQEPRDI.
When NOLOPEPRDI is set low, reporting of enhanced RDI is according to PSLMEPRDI ,
TIUEPRDI, TIMEPRDI and UNEQEPRDI and the associated alarm states.
PSLMEPRDI:
When set high, the PSLMEPRDI bit enables enhanced path RDI assertion when path signal
label mismatch (PSLM) events are detected in the receive stream. When PSLMEPRDI is
set high and PSLM occurs, bit 6 of the G1 byte is set high while bit 7 of the G1 byte is set
low.
When PSLMEPRDI is set low, path signal label mismatch events have no effect on path
RDI. In addition, this bit has no effect when EPRDI_EN is set low.
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 PSLMEPRDI , TIUEPRDI,
TIMEPRDI and UNEQEPRDI.
When NOPAISEPRDI is set low, reporting of enhanced RDI is according to PSLMEPRDI ,
TIUEPRDI, TIMEPRDI and UNEQEPRDI and the associated alarm states.
NOALMEPRDI:
When set high, the NOALMEPRDI bit disables enhanced path RDI assertion when loss of
signal (LOS), loss of frame (LOF) or line alarm indication signal (LAIS) events are detected
in the receive stream. When NOALMEPRDI is set high and one of the listed events occur,
bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set high. NOALMEPRDI has
precedence over PSLMEPRDI , TIUEPRDI, TIMEPRDI and UNEQEPRDI.
When NOALMEPRDI is set low, reporting of enhanced RDI is according to PSLMEPRDI ,
TIUEPRDI, TIMEPRDI and UNEQEPRDI and the associated alarm states.
