Dial-out On Alarm
Overview This section describes the configuration parameters and the algorithm
used for dial-out.
By default, the control unit is configured not to dial-out at all. It can be
configured to dial-out to a primary phone number or an alternate phone
number. The alternate phone number is used in the event that the control
unit fails to connect to the primary phone number. The control unit will
attempt to dial-out when an alarm occurs that it has not reported yet and
when all alarms retire.
Phone numbers may be up to 25 characters long and may contain any of
the following characters: 0123456789,()#* or space. Configuring the
phone numbers enables the control unit to dial-out. The phone number
must be the number of a modem. After the control unit connects to the
remote modem it will send an alarm report. The alarm report is the same
report generated by the T1.317 ala command with the addition of the site
id at the beginning of the report.
When attempting to dial-out, the control unit will first attempt to dial the
primary phone number. It will make up to three attempts, at 1-minute
intervals, to connect to the primary phone number. If unsuccessful, the
control unit will make up to three attempts, at 1-minute intervals, to
connect to the alternate phone number. If still unsuccessful, the control
unit will wait for 15 minutes and then repeat this cycle again. The cycle
will be attempted 6 times before giving up completely. If the control unit
successfully contacts either the primary or alternate phone number it
will send the alarm report and then disconnect.
Whether or not the control unit successfully connects with the primary
or alternate phone number, it will make a new attempt to dial-out when
a new alarm occurs or all active alarms clear.
