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 5 th Dialling 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.
