SATURN USER NETWORK INTERFACE (622-MAX)
When NOPAISEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI,
TIMEPRDI 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. 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 PSLMERDI, TIMEPRDI and UNEQERDI.
When NOALMEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI,
TIMEPRDI and UNEQERDI and the associated alarm states.
LCDEPRDI:
When set high, the LCDEPRDI bit enables enhanced path RDI assertion when loss of ATM
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.
