stream. If enabled, when the event 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. If enabled, when the event 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 and UNEQERDI.
When NOPAISEPRDI is set low, reporting of enhanced RDI is according to
PSLMERDI and UNEQERDI 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. If enabled, when these
events occurs, bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set
high. NOALMEPRDI has precedence over PSLMERDI and UNEQERDI.
When NOALMEPRDI is set low, reporting of enhanced RDI is according to
PSLMERDI and UNEQERDI and the associated alarm states.
LCDEPRDI:
When set high, the LCDEPRDI bit enables enhanced path RDI assertion
when loss of cell delineation (LCD) events are detected in the receive stream.
If enabled, when the event occurs, bit 6 of the G1 byte is set high while bit 7 of
the G1 byte is set low.
When LCDEPRDI is set low, loss of ATM cell delineation has no effect on path
RDI. In addition, this bit has no effect when EPRDI_EN is set low.
