(a) AIS-CI is a modified AIS alarm pattern. Equipment not suited to detect AIS-CI still detects this signal as an AIS. AIS-CI is sent
toward the network indicating that an LOS (RLOS) or AIS (RAIS) has been received from the CPE.

Remote Loss of Signal— Loss of the H2TU-R DS1 input signal.
Remote Alarm Indication Signal—Indicates an AIS (all ones) pattern is being received at
the H2TU-R DS1 input port. By default AIS-CI
Remote RAI - Remote Alarm Indication at the H2TU-R—Indicates an RAI alarm (yellow)
from the CPE with errors from the line unit or network.
Transmit RAI-CI - Remote Alarm Indication at the H2TU-R—Upon reception of an RAI
(yellow alarm) from the CPE, the H2TU-R sends a RAI-CI towards the network if the
network signal received at the H2TU-R is clear. If the network signal is impaired (LOS, AIS
or LOF), then the RAI is passed on to the network unaltered. This is applicable to SF or
ESF framing. In an all SF environment, RACI must be enabled to convert SF RAI to SF
RAI-CI.
Performance Report Monitoring - Near End—The count of the PRM-NE register at the
H2TU-R exceeds the 10
Performance Report Monitoring - Far End—The count of the PRM-FE register at the
H2TU-R exceeds the 10
Bit Error Rate—The DS1 BER has exceeded the built-in 24-hour threshold limits of
approximately 10
