UAS 7002 NIU
3-7
GDC 087R706-000-02
monitors performance alarm conditions both for itself (near-end) and for its remote (far-end).
The unit evaluates declared alarm conditions, such as Loss of Signal, simply on the basis of
whether or not the condition exists. If the alarm condition exists, the unit displays it as ACTIVE
on the Alarm Monitor terminal interface screen and generates an SNMP trap to report it if it isn’t
masked.
The unit evaluates performance alarm conditions, such as Errored Seconds, on the basis of Time
Interval and Count Threshold values configured separately for each alarm condition. The options
for doing that configuration compose the Alarm Thresholds screens. The threshold is the number
of times the condition must occur before the unit reports the alarm. The interval is the time span
within which the threshold value must be reached or exceeded in order for the unit to report the
alarm. These values govern both SNMP reporting and terminal interface display.
Figure 3-6 illustrates the Near-End Alarm Thresholds screen, which contains the selections for
setting a Time Interval and Count Threshold for each near-end (local) performance alarm. The
Far-End Alarm Thresholds screen is identical.
The alarm configuration procedure appears following the figures.
