cOpticalParamLowAlarmThresh
CERENT-OPTICAL-MONITOR-MIB ·
.1.3.6.1.4.1.3607.2.30.1.1.1.7
Object
This object is used to set a low alarm threshold on the
optical parameter being monitored.
If the measured value of the parameter,goes lower than the
value configured in this object, an alarm will be raised.
When the cOpticalMonParameterType object is set to 'power'
for the receive direction and when the interface supports
alarms based on loss of light, this object specifies the
optical power threshold for declaring loss of light. Also,
when optical amplifiers are present in the network, in the
receive direction, this value may need to be configured,
since the noise floor may be higher than the minimum
sensitivity of the receiver.
