11.5 NCO – Node Communications Status
11.5.1 Description
If Optical Master Unit is configured as a node master monitoring a number of slave
repeaters over the optical fiber, this alarm is used to indicate status of the actual
communication.
A communications alarm might indicate that fiber connection is unplugged or that
repeater is down.
11.5.2 Threshold Usage
This is a status measurement, either OK or ERROR. Hence, upper and lower thresholds
are ignored.
11.5.3 Time
Time threshold configures after how many consecutive communication errors with node
that an alarm should be triggered.
11.5.4 Upper
Not used.
11.5.5 Lower
Not used.
11.6 PW1 – Power Supply 1
11.6.1 Description
The Power Supply 1 is the +28 V distribution as measured in the in the Rack
Communication Board in the different racks of the Optical Master Unit.
If level is outside configured interval, an alarm is triggered.
11.6.2 Threshold Usage
By default, both upper and lower thresholds are used in the PW1 alarm.
11.6.3 Time
Time threshold defines how many seconds the alarm should be measured as in error
before an alarm is triggered.
11.6.4 Upper
Upper threshold is maximum voltage level * 10 of the power supply before an alarm is
triggered. For example, configuring the upper level as 295 means that if voltage level
exceeds 29.5 V, an alarm is triggered.
11.6.5 Lower
Lower threshold is minimum voltage level * 10 of the power supply before an alarm is
triggered. For example, configuring the lower level as 270 means that if voltage level
drops below 27.0 V, an alarm is triggered.
11.7 PW2 – Power Supply 2
11.7.1 Description
The Power Supply 1 is the +15 V distribution as measured in the in the Rack
Communication Board in the different racks of the Optical Master Unit.
If level is outside configured interval, an alarm is triggered.
