Bit 0: Receive Carrier-Loss (RCL) Alternate Criteria (RCLA). Defines the criteria for a receive carrier-loss
condition for both the framer and LIU.
0 = allow RSERO to output data as received under all conditions
1 = force RSERO to 1 under loss-of-frame alignment conditions
0 = CAS signaling mode
1 = CCS signaling mode
0 = HDB3 disabled
1 = HDB3 enabled
0 = do not force RCHBLK high during bit 1 of time slot 26
1 = force RCHBLK high during bit 1 of time slot 26
0 = CRC4 disabled
1 = CRC4 enabled
0 = resync if FAS received in error three consecutive times
1 = resync if FAS or bit 2 of non-FAS is received in error three consecutive times
0 = auto resync enabled
1 = auto resync disabled
0 = RCL declared upon 255 consecutive 0s (125μs)
1 = RCL declared upon 2048 consecutive 0s (1ms)
