Alarm

Description

LOSW

COLU cannot receive data over the given HDSL loop. COLU and RT cannot synchronize and is out of

service.

ES-15

Number of HDSL ES has exceeded the user-configurable threshold to give advance warning that HDSL

Min.

performance is deteriorating. You can set this threshold from 0-15 ES over a 15-minute period, or disable

the alarm completely. 24 hour ES alarm threshold reached or exceeded.

ES-24 Hr. Number of HDSL ES has exceeded the user-configurable threshold to give advance warning that HDSL

performance is deteriorating. You can set this threshold from 0-255 ES over a 24-hour period, or disable

the alarm completely. 24 hour ES alarm threshold reached or exceeded.

MAR

HDSL noise margin of the loop has fallen below the user-configurable threshold. HDSL MAR reaches

or drops below the current threshold value.

PFO

COLU cannot power the RT due to an open circuit. An undercurrent condition as detected by the RT

exists for the given pair (<20 mA). A possible cause is that there is no RT at the other end of the circuit.

No user intervention is required.

PFS

COLU cannot power the RT due to a short circuit. An excessive current condition as detected by the

COLU exists for either pair (>50 mA). A PFS alarm indicates an overcurrent condition due to wire

shorting or an RT failure. The COLU automatically turns off power feeding to both loops in response to

a PFO or PFS condition on a single loop. No user intervention is required.
