SilentKnight VisorALARM High Availability Receivers - Manual (Page 3)

Introduction
The Alarm Monitoring Service, as any other mission critical service, has tight restrictions
on its availability. As any mission critical service, any loss of performance or service
failure can derive into a high loss of revenue, customer dissatisfaction and, what it is
worse, it can lead to loss of human lives.
Disaster Recovery Plans spans over all service elements, coordinating them together in in
seek of the highest availability. There are diverse ways to implement Disaster Recovery
Plans for Alarm Monitoring Services. However, all of them have something in common:
they must be supported over the most robust communications paths.
This important challenge becomes a big concern in IP-based alarm systems, hence the
need for intelligent platforms that can automatically react to network service breakdowns
to keep the Alarm Service running without losing any performance.
The Teldat IP Alarm system adds the IP Communication path to the traditional Alarm
System. The high availability improvement over the telephone network elements
achieves this goal by delivering line redundancy to the Fire Panel side, as well as to the
Central Monitoring Station (CMS). The line redundancy in the CMS can be combined
with equipment redundancy – the VisorALARM’s are grouped in clusters

.
This document describes Teldat’s IP line redundancy in the CMS network. The backup
process is detailed and all the system elements are listed. In the next section, the Teldat
IPDACT-2/2UD and VisorALARM text configuration parameters required for the IP
backup are explained. Finally, a detailed explanation on the Teldat IP Alarm System
troubleshooting is given.
