CI Alarm Transmit (Only in ESF)
These two bits are used to enable or disable AIS-CI or RAI-CI gen-
eration in T1 ESF mode only.
Alarm Indication Signal-Customer Installation (AIS-CI) and Remote
Alarm Indication-Customer Installation (RAI-CI) are intended for use
in a network to differentiate between an issue within the network or
the Customer Installation (CI).
AIS-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.
RAI-CI
Remote Alarm Indication - Customer Installation (RAI-CI) is a repeti-
tive pattern with a period of 1.08 seconds. It comprises 0.99 sec-
onds 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. RAI-CI applies to T1 ESF framing mode only.
00/11 = Disables RAI-CI or AIS-CI alarms generation
01 = Enables unframed AIS-CI alarm generation
10 = Enables RAI-CI alarm generation

CI Alarm Detect (Only in ESF)
These two bits are used to enable or disable RAI-CI or AIS-CI alarm
detection in T1 ESF mode only.
00/11 = Disables the RAI-CI or AIS-CI alarm detection
01 = Enables the unframed AIS-CI alarm detection
10 = Enables the RAI-CI alarm detection
