Field Description
Performance
MAR1 Displays the Margin value for the HDSL Loop 1 interface at the LTU
and NTU or displays link status (SIG, ACK, etc.) if the link is not up.
MAR2 Displays the Margin value for the HDSL Loop 2 interface at the LTU
and NTU or displays link status (SIG, ACK, etc.) if the link is not up.
ES1 Displays the errored second counts for the LTU and NTU DSX-1 ports
and the HDSL Loop 1 interface at the LTU and NTU. The counts are for
the latest 24-hour period, including the current 15-minute interval.
ES2 Displays the errored second counts for the LTU and NTU Nx64k ports
and the HDSL Loop 2 interface at the LTU and NTU. ES2 is calculated
the same as for ES1.
Alarms
The Alarms field displays a list of all active alarms at the LTU and NTU interface and the
HDSL Span 1 interface.
Possible LTU and NTU Interface alarms:
LOS Loss of signal at the DSX-1 or Nx64k input.
LFA Loss of frame alignment at the DSX-1 input (structured mode only).
AIS Alarm Indication Signal (unframed all ones) received at the DSX-1
input.
RAI Remote Alarm Indication Signal received at the DSX-1 input
(structured mode only).
LOC Loss of clock when EXT timing is used. The external clock was lost for
the previous second. This alarm is reset when the clock is active again.
Possible HDSL Span 1 alarms:
MAR Margin has fallen below alarm threshold for one or both loops of
HDSL Span 1.
ES Errored second count has exceeded alarm threshold for one or both
loops of HDSL Span 1.
LOSW Loss of sync word for one or both loops of HDSL Span 1. Remains
active during restart, but not a cold start.
PFO Power feed open for one or both loops of HDSL Span 1. Remains
active until power is successfully fed to remote unit, or remote power
feeding is disabled.
PFS Power feed short for one or both loops of HDSL Span 1. Remains
active until power is successfully fed to remote unit, or remote power
feeding is disabled.
NOPSW Protection circuit (backup) is not available.
