Alternate Dialing Attempts
Alternate dialing is an option available in the majority of the reporting services and results in the reporting phone
numbers programmed in the service being dialed in an alternative sequence. In the following example, a service
is programmed with two telephone numbers (Phone 1 and Phone 2) and a backup telephone number. The
number of dialing attempts is set to 8 and the Use Alternate Dialing Method option has been enabled.
If alternate dialing is enabled for the reporting service it is recommended that the monitoring company is
informed and that they can make the appropriate programming arrangements.
Success After 5th Dialing Attempt With Phone Number 1
In the following example, the Controller was able to communicate with the central station with the programmed
phone number 1 on the 5th attempt. As can be seen the back up phone number is dialed on each alternative
failure. This is an extreme example most reports would have been received on the backup phone typically on
the second attempt.

result of the reporting failure. This is subsequently sealed on the next valid report.
