The Signal Quality value that will trigger the alert.
Deadband
The Deadband is a buffer zone so the alerts do not toggle on and off when the Signal
Quality fluctuates around the alert limit. The alert is set when value falls below the alert
limit. The alert is then cleared when value rises above the Deadband range.
High/low level alerts
High/Low Level Alerts are triggered when the level goes outside the user defined Limits.
There are four standard Level Alerts. Hi Level Alert and Hi-Hi Level Alert are used for rising
levels, and Lo Level Alert and Lo-Lo Level Alert are used for falling levels. See
Figure D-9
