4.5.2 – Direct and Indirect Alarms
There are two type of alarms :
• Direct alarms which occur when there is a fault on the unit (i.e. transmit frequency alarm)
• Indirect alarms caused by an other module failure, or by a missing unit or by a propagation
problem (RSL alarm, BER alarm, demodulation alarm….)
To determine the cause of an indirect alarm, it is necessary to analyze all possible causes which can
cause such an alarm, and to select the most probable.
.
4.5.3 – Equipment Log
The view equipment log feature is also very useful to determine graphically the cause of a problem,
because all active alarms are displayed versus time.
