primary and secondary telephone numbers are entered. The maximum number of call
attempts is also important so that the alarm panel continues to redial both telephone
numbers for a reasonable period of time.
If the alarm panel dials the primary telephone number, the ATA will attempt to transmit
the signal over the Internet. If successful, the monitoring server will send a response to
the alarm panel so that it knows the signal was accepted. If the Internet is not available,
the signal will not be able to reach the monitoring server and the signal will fail. At this
stage, and if programmed correctly, the alarm panel will commence dialling the secondary
telephone number.
When the secondary telephone number is detected by the ATA, it redirects the dialled
digits to its FXO port – normally referred to and labelled as the LINE Port. If the Line Port
is connected into a PSTN landline socket, the telephone number of the alarm receiver at
the Monitoring Center will be dialled over the PSTN (POTS) landline.
If the Line Port is connected to a cellular backup device with a dialler capture feature, it
will handle the dialled digits and transmit the alarm message over the relevant cellular
network.
Using Line 2 for VoIP Service
If permitted by your alarm monitoring provider and VoIP service provider, it is possible to
use Line 2 of a two-line ATA for voice service. Please follow these three steps to enable
this:
1. Reset your ATA to its default settings through the IVR (**** 73738# 1).
2. Enter your VoIP settings into the Line 2 tab. DO NOT change settings on any other
tab.
3. Provision your ATA with the Alarm Monitoring Provisioning Server.
Connect your alarm panel to the Phone 1 port and a telephone handset to the Phone 2
port of your two-line Linksys device. If some time later you need to overwrite the settings
for Line 2, it is possible to do this from the Provisioning Server without having to reset and
re-provision the device.
Every provisioned ATA will check the provisioning server once a day to find out if any new
settings need to be downloaded. This makes it easy to update every device out in the field
should a “global” update of main settings be required. It also allows minor custom settings
to be downloaded on a per device basis.
Remote Panel Programming (Upload/Download)
For panel initiated remote programming, you can either leave the Downloading Computers
Telephone Number in the alarm panel as it is, or set it to 9997 if this is the first time
downloading has been setup. Program all other downloading options in the panel
accordingly and make sure they match what is programmed in the downloading software
at the Alarm Company office.
