Bit

FRM_ORAI
Name
Other Remote Alarm Indication. A 1 indicates the receive
framer detected an other remote (yellow) alarm. This bit is a 0 in
the modes not indicated below. This bit is set when the alarm is
detected, and is cleared on a read of this register if the alarm is
not detected during the read.
J-D4 RJYA: The frame bit in frame 12 is a 1 two out of three
consecutive times.
ESF, J-ESF RAI-CI:
Option 0: A 1 indicates the receive framer detected remote
alarm indication customer installation (RAI-CI) in the ESF data
link. RAI-CI is a repetitive pattern with a 1.08 second period. It
consists of 0.99 s of the unscheduled message 00000000
11111111 (RAI in the data link) interleaved with
0.09 s of the RAI-CI signature pattern. The RAI-CI signature
pattern is 00111110 11111111 (transmitted right-to-left). ( ANSI
T1.231 section D.1.2.)
Option 1: A 1 indicates the receive framer detected RAI-CI in
the ESF data link. RAI-CI is a repetitive pattern with a 1.08 sec-
ond period. It consists of 0.99 s of all ones (RAI in the data link)
interleaved with 0.09 s of the RAI-CI signature pattern. The RAI-
CI signature pattern is 00111110 11111111 (transmitted right-
to-left). ( ANSI T1.231 section D.1.2.)
CEPT RTS16MFA: Bit 6 of time slot 16 of signaling frame 0 is a
1 for three consecutive occurrences. The alarm is considered
inactive when bit 6 of time slot 16 of signaling frame 0 is 1 in
less than two consecutive occasions. This is true if time slot 16
is not carrying a payload, e.g., common channel signaling. If
time slot 16 is used for common channel signaling, bit 6 will be
continuously 1. In this case, it will be possible to inhibit the
remote alarm to prevent false alarm conditions. (O.162 section
2.1.5.) This is the y-bit input from the signaling block.
