Receive Alarm Indication Signal-Customer Installation (AIS-CI) State
This READ ONLY bit field indicates whether or not the Receive T1 Framer is
currently detecting the Alarm Indication Signal-Customer Installation (AIS-
CI) condition.
Alarm Indication Signal-Customer Installation (AIS-CI) is intended for use in
a network to differentiate between an issue within the network or the Cus-
tomer Installation (CI).
AIS-CI is an all ones signal with an embedded signature of 01111100
11111111 (right-to left) which recurs at 386 bit intervals in-the DS-1 signal.
0 = Indicates the Receive T1 Framer is currently NOT detecting the AIS-CI
condition
1 = Indicates the Receive T1 Framer is currently detecting the AIS-CI condi-
tion
NOTE: This bit only works if AIS-CI detection is enabled (Register 0x011C)

Rx RAI-CI State
This READ ONLY bit field indicates whether or not the Receive T1 Framer is
currently declaring the Remote Alarm Indication - Customer Installation
(RAI-CI) condition. (This is for T1 ESF framing mode only)
Remote Alarm Indication - Customer Installation (RAI-CI) is intended for use
in a network to differentiate between an issue within the network or the Cus-
tomer Installation (CI).
RAI-CI is a repetitive pattern with a period of 1.08 seconds. It is comprised of
0.99 seconds of RAI message (00000000 11111111 Right-to-left) and a 90
ms of RAI-CI signature (00111110 11111111 Right to left) to form a RAI-CI
signal.
0 = Indicates the Receive T1 Framer is currently NOT detecting the RAI-CI
condition
1 = Indicates the Receive T1 Framer is currently detecting the RAI-CI condi-
tion
NOTE: This bit only works if RAI-CI detection is enabled (Register 0x011C)
