If enabled, the network interface receiver requires the NFAS word (TS0 0 in odd
frames) and the FAS word (TS0 0 in even frames) for frame sync. When dis-
abled, only the FAS word is needed for frame sync.

If enabled, the receiver requires MFAS word in TS16 to achieve sync. The trans-
mitter outputs MFAS word in TS16 (see also, CAS on page 3-11).

Transmits the CRC-4 checksum bits in the outgoing E1 data stream, when
enabled. Also, checks the received signal for errors.
Write security: 3; Read security: 5
Transmits a remote alarm when framing is lost (when Red Alarm Generation is
on), and transmits an AIS alarm when all ones are received (when RCM AIS
