Description
ALARMS
LLOS
Local Loss of Signal
No signal from HLU-388 local T1 input.
RLOS
Remote Loss of Signal
No signal from HRU T1 input.
LOSW1 LOSW2
Loss of Sync Word 1 or 2
One of the HDSL loops has lost synchronization.
H1ES
HDSL Loop 1 Errored Second
Loop 1 CRCs have exceeded the user-selected ES threshold.
H2ES
HDSL Loop 2 Errored Second
Loop 2 CRCs have exceeded the user-selected ES threshold.
DS1
Digital Service 1
T1 input BPVs, at either the HLU-388 or the HRU, have exceeded the
user-selected ES threshold.
RAIS/LAIS
Remote/Alarm Alarm Indicating
Signal
Indicates an AIS (all ones) pattern is being transmitted (XMT) from the
remote/local T1 output port.
MAL1
Margin Alarm 1
The margin on the HDSL loop 1 has dropped below the threshold
(1 to 15 dB) set by the user. Setting the threshold to zero inhibits the
margin alarm.
MAL2
Margin Alarm 2
The margin on the HDSL loop 2 has dropped below the threshold
(1 to 15 dB) set by the user. Setting the threshold to zero inhibits the
margin alarm.
CHREV
Channels Reversed
The loop 1 and loop 2 HDSL pairs are reversed at the HRU input port.
Loop 1 is specified to carry the (-) simplex DC voltage, and loop 2 is
specified to carry the (+) simplex DC voltage.
ACO
Alarm Cut-Off
A minor alarm occurred and was retired by pressing the SEL button on
the HLU-388 front panel.
LOOPBACKS
SMJK
SmartJack Loopback
Loopback from HRU to network initiated by (2-in-5) in-band loopback
code or out-of-band ESF data link code.
NREM
Network Remote Loopback
Loopback at HRU to network initiated from CO (network) by Intelligent
Line Repeater (ILR) #2 code, Manual Loopback buttons on the
HLU-388 front panel, HRU front panel button or by the maintenance
terminal.
NLOC
Network Local Loopback
Loopback HLU-388 (local) to network initiated from CO by IOR code,
the HLU-388 front panel Manual Loopback buttons or maintenance
terminal.
CLOC
Customer Local Loopback
Loopback at HRU (local) to CI initiated from CPE by the ILR #2 code
or the Manual Loopback buttons on the HLU-388 front panel or by the
maintenance terminal.
CREM
Customer Remote Loopback
Loopback at HLU-388 (remote) to customer initiated by IOR code or
the Manual Loopback buttons on the HLU-388 front panel or by the
maintenance terminal.
ARM
Armed
The HiGain system has detected the IR loopback (2-in-5) arming code.
TLOS
Transmit Loss of Signal Loopback
HRU is in a logic loopback state caused by a loss of its T1 input from
the CI (if enabled at the HRU via its TLOS switch option).
