is disabled, by default. When set, Double Acknowledgement assures
that a cleared alarm is acknowledged before the alarm is removed
from the Alarm List for an NE.
Alarm Details are available to the user via the Alarm List window.
This window contains a line of information about each active alarm in
an NE or aggregate. Before acknowledging an alarm, it is a good
practice to display it on the Alarm List window to check the details
and make sure you want to acknowledge it. You can then perform the
acknowledgement right from the Alarm List window.
Trails are physical links between NEs. The system monitors all
existing trails for alarm conditions.
NEs can only automatically discover and report to Navis
EMS trails over which there is an active Data Communications
Channel (DCC). Users can, however, add trails between any pair of
termination points on NEs.
The following Information about trail alarms that have occurred can
either be displayed on the Alarm Summary window or by selecting
the trail:
•
Trail Alarm Summary Window—this lists a count of critical,
major, and minor alarms for the AIDs that terminate the trail
between two NEs.
•
Trail Alarm List—this contains a line of information about each
active alarm for the trails between two NEs. This information
includes alarm severity, occurrence date/time, condition, and
date/time logged.
Alarm Resynchronization provides the ability for the system to update
its alarm list, autonomous message log, and command/response log
from network elements in the subnetwork whenever any outage of NE
communications occurs. The system automatically resynchronizes
alarms whenever the communications status with an NE changes from
"down" to "up."
Before resynchronizing alarms for an NE, the user should disable the
automatic/manual alarm throttling control for the NE. Alarm
resynchronization does not work unless the NE is in an unthrottled
state.
