Scope
The chapter includes procedures to view the alarms, their severity level, the associated
probable cause(s), as well Alcatel-Lucent recommended trouble-clearing action(s).
However, specific procedures to restore network nodes to normal operation after
system failures are described in the Alarm Messages and Trouble Clearing Guide and
will not be covered in this chapter.
High level view
Maintenance involves two groups of activities: preventive and corrective. The ITM-CIT
offers a collection of corrective activity features that are described all together as Event
Management. To accomplish this, the ITM-CIT provides the user with information
regarding the event location, nature, probable cause, severity, as well as a
recommended trouble-shooting action.
As an example, the table below gives a non-exhaustive list of maintenance activities
that can be performed on the management system. Most tasks are correlated to one (or
more) ITM-CIT window (s).
Maintenance Activities Using ITM-CIT
1. Identify the alarms: Station Alarms, Bay Alarms, Unit
Alarms, ITM-CIT alarms;
Yes (only for CIT
alarms)
2. Evaluate severity of alarm, the correlated alarms, the
probable cause(s);
Yes
3. Identify the alarm source physical location; Yes
4. Interpret the information No
5. Recommend trouble-clearing action; Yes
6. Take action (depending on the alarm) Yes
7. Perform preventive maintenance (please refer to Chapter
10, “Performance monitoring”)
Yes
This chapter will describe the relevant windows where the ITM-CIT can be used to
complete the above-mentioned job tasks. The first three tasks of the previous table
consist in collecting information in order to make a decision concerning the resolution
of the alarm. These tasks can be completed by consulting the information available in
the relevant ITM-CIT windows.
