alerts or alarms based on either the total number of PDIF calls
setup by the system during the specified polling interval, or on
the number of currently active calls only.
Alerts or alarms are
triggered for call setups based on the following rules:
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 value is 0,
which means there will be no monitoring.
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.
