Thresholds generate alerts or alarms based on either the total number of ePDG calls setup by the system during the specified polling interval, or on the number of currently active calls only.
Enter condition: Actual number of call setups > or = High Threshold
Clear condition: Actual number of call setups < Low Threshold
If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.
Default ePDG threshold polling interval value is 5 Min.
The polling interval is in seconds and it is an integer between 30 and 60000. Entries will be rounded up to the nearest 30 seconds.
