Description
LLOS
Local Loss of Signal
No signal from ELU-319 List 5E local E1 input.
RLOS
Remote Loss of Signal
No signal from ERU E1 input.
LOSW1 LOSW2
Loss of Sync Word 1 or 2
One of the HDSL loops has lost synchronization.
BER
Bit Error Rate
The total system error count (TSEC) has exceeded the user-selected
threshold.
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 ERU input port.
Loop 1 is specified to carry the (-) simplex DC voltage, and Loop 2 is
specified to carry the (+) simplex DC voltage.
NREM
Network Remote Loopback
Loopback at ERU to network initiated from CO (network) by Intelligent
Line Repeater (ILR) #2 code, Manual Loopback buttons on the
ELU-319 List 5E front panel, ERU front panel button or by the
maintenance terminal.
NLOC
Network Local Loopback
Loopback ELU-319 (local) to network initiated from CO by IOR code,
the ELU-319 List 5E front panel Manual Loopback buttons or
maintenance terminal.
NDU1
Network Doubler 1 Loopback
Loopback at Doubler #1 to network initiated by IOR code or by Manual
Loopback buttons on the ELU-319 List 5E front panel or by the
maintenance terminal.
NDU2
Network Doubler 2 Loopback
Loopback at Doubler #2 to network initiated by IOR code or by Manual
Loopback buttons on the ELU-319 List 5E front panel or by the
maintenance terminal.
NDU3
Network Doubler 3 Loopback
Loopback at Doubler #3 to the network initiated by IOR code, the
Manual Loopback buttons on ELU-319 List 5E front panel or by the
maintenance terminal.
CLOC
Customer Local Loopback
Loopback at ERU (local) to CI initiated from CPE by the ILR code or the
Manual Loopback buttons on the ELU-319 List 5E front panel or by the
maintenance terminal.
CREM
Customer Remote Loopback
Loopback at ELU-319 List 5E (remote) to customer initiated by IOR
code or the Manual Loopback buttons on the ELU-319 List 5E front
panel or by the maintenance terminal.
CDU1
Customer Doubler 1 Loopback
Loopback at Doubler #1 to CI initiated by ILR code, the Manual
Loopback buttons on ELU-319 List 5E front panel or by the
maintenance terminal.
CDU2
Customer Doubler 2 Loopback
Loopback at Doubler #2 to CI initiated by ILR code, the Manual
Loopback buttons on the ELU-319 List 5E front panel or by the
maintenance terminal.
CDU3
Customer Doubler 3 Loopback
Loopback at Doubler #3 to CI initiated by ILR code or by Manual
Loopback buttons on the ELU-319 List 5E front panel or by the
maintenance terminal.
TLOS
Transmit Loss of Signal Loopback
ERU is in a logic loopback state caused by a loss of its E1 input from
the CI (if enabled at the ERU via its TLOS switch option).
