Automatic Remote Frame Alarm on LFA (ARLFA). A 1 transmits the remote frame
alarm to the line whenever the receive framer detects loss of frame alignment (RLFA).
receive framer detects loss of time slot 16 signaling multiframe alignment
(RTS16LMFA).
Automatic A Bit on LMFA (CEPT Only). A 1 transmits A = 1 to the line whenever the
receive framer detects loss of time slot 0 multiframe alignment (RTS0LMFA).
Automatic A Bit on CRC-4 Multiframe Reframer Timer Expiration (CEPT Only). A 1
transmits A = 1 to the line when the receive framer detects the expiration of either the
100 ms or 400 ms timers due to loss of multiframe alignment.
Automatic A Bit on RSa6_8 (CEPT Only). A 1 transmits A = 1 to the line whenever the
receive framer detects the Sa6 = 1000 pattern.
Automatic A Bit on RSa6_C (CEPT Only). A 1 transmits A = 1 to the line whenever the
receive framer detects the Sa6 = 1100 pattern.
Transmit D4 Japanese Remote Frame Alarm. A 1 transmits a valid Japanese remote
frame alarm for the D4 frame format.
Transmit Remote Frame Alarm. A 1 transmits a valid remote frame alarm for the corre-
sponding frame format.
