Description
35)
Line (Unit) Loss of Signal—Loss of the H4TU-C DSX-1 input signal.
Line Alarm Indication Signal—Indicates an AIS (unframed all ones) pattern is being received at the
H4TU-C DS1 input port.
Bit Error Rate—The DS1 BER has exceeded the built-in 24-hour threshold limits of approximately 10
(xxx denotes either TUC or TUR.)
Loss of Frame—Indicates the incoming DS1 frame pattern is other than the one selected, ESF or SF,
by the FRMG option. Only occurs if the FRMG option is set to SF or ESF. (xxx denotes either TUC or
TUR.)
23)
Remote (Unit) Loss of Signal—Loss of the H4TU-R DS1 input signal.
Remote Alarm Indication Signal—Indicates an AIS (unframed all ones) pattern is being received at the
H4TU-R DS1 input port. By default AIS-CI
Remote RAI - Remote Alarm Indication at the H4TU-R—Indicates an RAI alarm (yellow) from the CPE
with errors from the line unit or network.
Line (Clear) Remote Alarm Indication—An RAI condition is detected at the remote and the signal from
the line unit is error-free. RAI signal is transmitted towards the network.
Performance Report Messaging - Near End—The count of the PRM-NE register at the H4TU-R exceeds
-6
the 10
BER threshold at 648 events since 12:00:00 AM.
Performance Report Messaging - Far End—The count of the PRM-FE register at the H4TU-R exceeds
-6
the 10
BER threshold at 648 events since 12:00:00 AM.
Bit Error Rate—The DS1 BER has exceeded the built-in 24-hour threshold limits of approximately 10
(xxx denotes either TUC or TUR.)
