The RPAISINS_EN bit is used to enable the RHPP’s AIS and LOP indications to be
propagated to the SVCA output on a per-timeslot basis. Thus, when an AIS-L, AIS-P, or LOP
are detected, the SVCA will generate a proper AIS-P on its output. This bit and the
RLAISINSEN, PAISPTREN, PLOPTREN registers bit in the SARC Path RPAISINS
Enable indirect register (0x072A) for all 12 available SARC timeslots (see Section
13.17.3) must be set to logic 1 for proper operation.
The SD_DEFECT_EN bit is used to force an AIS-L on the internal datapath immediately
when SD is deasserted. This will prevent the internal framer’s (RRMP) descrambler from
producing a scrambled all 0’s pattern which, when passed through a transmitter’s scrambler
will generate the all 0’s pattern again. An extended all 0’s pattern at the transmitter could
potentially cause a loss of lock a the downstream receiver.
The LOS_DEFECT_EN bit is used to force an AIS-L on the internal datapath immediately
when an LOS is detected. This will prevent the internal framer’s (RRMP) descrambler from
producing a scrambled all 0’s pattern which, when passed through a transmitter’s scrambler
will generate the all 0’s pattern again. An extended all 0’s pattern at the transmitter could
potentially cause a loss of lock a the downstream receiver.
