Alarm Masks Configuration Screen
The Alarm Masks Configuration Submenu lists all the alarms that the 7001 can report. Consult
the description of the Monitor/Alarms screen for definitions of the alarm conditions. The alarms
are divided into the categories Declared and Performance.
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 CRC Errors, on the basis of Time
Interval and Count Threshold values configured separately for each alarm condition. The options
for doing that configuration compose the Performance Alarm Thresholds Submenu. 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.
