E1 FRAMER/TRANSCEIVER
signalling multiframe alignment signal, 0000, is substituted with 1111); when
set to logic 0, the signalling multiframe alignment signal is unchanged.
REMAIS:
The REMAIS bit controls the transmission of the remote Alarm Indication
Signal. A logic 1 in the REMAIS bit position causes bit 3 of NFAS frames to
be forced to logic 1; otherwise, bit 3 of NFAS frames is a logic 1.
MFAIS:
The MFAIS bit controls the transmission of the signalling multiframe Alarm
Indication Signal. A logic 1 in the MFAIS bit position causes the y-bit (bit 6) of
TS16 of frame 0 of the signalling multiframe to be forced to logic 1; otherwise,
the y-bit is a logic 1.
TS16AIS:
The TS16AIS bit controls the transmission of the Time Slot 16 Alarm
Indication Signal (all-ones in TS16). A logic 1 in the TS16AIS bit position
forces TS16 of all frames in the output stream to logic 1.
AIS:
The AIS bit controls the transmission of the Alarm Indication Signal
(unframed all-ones). A logic 1 in the AIS bit position forces the output
streams to logic 1.
When the E1XC is reset, the contents of this register are set to logic 0.
