RSL Deviation Alerts

Overview

The NFM-P supports raising an alarm when the minimum RSL deviates from the installed RSL by a configurable deviation value. This procedure describes how to configure the deviation value and set up the NFM-P to monitor RSL deviation on a Wavence device by enabling RSL monitoring, and creating a custom Threshold Crossing Alarm rule that alerts the NFM-P when a deviation has occurred.

Steps
 
1 

Click Administration→System Preferences in the NFM-P main menu. The System Preferences form opens.

2 

In the Wavence tab, enable the Enable RSL Monitoring And Deviation Alert parameter, and configure the Maximum Allowed Number of Deviations parameter with the number of deviations that must occur before an alarm is raised. Save and close the form.

3 

Click Tools→TCA Policies in the NFM-P main menu. The TCA Policies form opens.

4 

Click Create. The TCA Policy form opens.

5 

Configure the Monitored Object Type parameter as the object type you need to monitor (for example, UBT Channel).

6 

Enable the TCA Admin State parameter.

7 

In the Custom panel, click Create. The Custom TCA form opens.

8 

Configure the following parameter values:

In the Rules panel, click Create. The Custom TCARule form opens.

Create a rule that defines when to raise the Threshold Crossing Alarm. For example, configure the following parameters to trigger an alarm when there is a deviation of more than -1 dB. Then save and close the form.

In the Custom panel, click Create and create a second rule that defines when to clear the Threshold Crossing Alarm raised by the previous rule. For example, configure the following parameters to clear the alarm when the deviation falls below -1 dB. Then save and close the form.

Click on the Monitored Object tab, and click on Add to add the Wavence network objects that you need to monitor. Save and close the form.

When the Threshold Crossing Alarm is triggered, the NSP raises a RSL Deviation Threshold Crossed alarm against the radio link associated with the monitored object. Both alarms can be viewed and managed in the NSP.
