A test mode initiated by the HMU which splits the AUX port's DSX-1 payload and sends it to the
MUX port.
A test mode initiated by the HMU which splits the AUX facility DS payload from the AUX port
#1 and sends it to the MUX port.
Local Loss of Signal—Loss of the H2TU-C DSX-1 input signal.
Line Alarm Indication Signal—Indicates an AIS (all ones) pattern is being detected at the
H2TU-C DS1 input port. The ALMP option determines whether AIS (default) or LOS is sent
towards the CPE.
Bit Error Rate—The DS1 BER has exceeded the built-in 24-hour threshold limits of
-6
approximately 10 . (xxx denotes either TUC or TUR.)
above)
Remote Loss of Signal— Loss of the H2TU-R DS1 input signal.
Remote Alarm Indication Signal—AIS is being detected at the H2TU-R DS1 input port. By
default (see Figure 30 on page
Remote Alarm Indication—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
LED) from the CPE, the H2TU-R sends an 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
-6
exceeds the 10 BER threshold at 648 events since 12:00:00 AM.
Performance Report Monitoring - Far End—The count of the PRM-FE register at the H2TU-R
-6
exceeds the 10 BER threshold at 648 events since 12:00:00 AM.
