4.3.5 FAULT
MANAGEMENT
Fault management involves inspecting and changing the thresholds and managing alarm conditions.
Generally, failure is caused due to radio signal (poor radio signal), equipment (module failure) and
site (power, over temperature).
The alarm is colour-coded to indicate its status and alarm levels. The alarm level is equipment
specific. It could be: Alarm, Warning, Error or Critical.
y
Green: Normal, no alarm is generated.
y
Red: Alarm is generated; the alarm level could be: Alarm, Warning, Error, or Critical.
On the tool bar of the main OMT screen, there is an “Alarm Indicator” showing the alarm level in real-
time. Should a critical alarm occur, the alarm indicator will remain at ‘red’.
4.3.5.1 ALARM ACKNOWLEDGEMENT
If the alarm is not acknowledged by OMC after a time-out of three minutes, or not acknowledged
within OMT, the same alarm will be reported to OMC.
After each time-out, the un-acknowledged alarm will be reported again with a total of three attempts.
Should the alarm be acknowledged within the time-out period, the reporting stops.
Alarm is cleared after the necessary diagnosis and rectification has been carried out. The on-screen
indicator for the designated alarm indicator should turn to green.
Every twenty-four hours, the equipment will be reset automatically; any alarm messages held within
the equipment would be cleared.
For every five dial-up attempts, the equipment will be reset automatically; any alarm messages held
within the equipment would be cleared.
If the ‘Power Supply’ is ‘ON’, then no alarm will be generated for the following conditions: Power
Down, Power Fault.
