Other Remote Alarm Indication. A 1 indicates the receive
framer detected another 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.
0
J-D4 RJYA: The frame bit in frame 12 is a 1 two out of three
consecutive times.
ESF, J-ESF: 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 signal-
ing. 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.
