Redundancy of key components
The brief
Communication with no single point of failure
As the transmission system operator, CGES manages infrastructure of strategic importance spread across Montenegro. The dispatch centre, headquarters building and substations had to be connected into a single communication system, available at all times.
TRS delivered and implemented a virtualised IP telephony platform and active network equipment at all sites, with full redundancy of critical components and centralised management of the entire system.
Scope of the solution
A redundant platform for every site
The system was built so that every critical component has a backup, and all sites run on a single, centrally managed platform.
Redundant SBC
Session Border Controller in a redundant configuration, for uninterrupted SIP traffic to the public network.
Dispatch consoles
Operator consoles with automatic recording of all dispatch calls, in line with regulations.
Central management
Management of the entire system, users and configuration through the OmniVista 8770 platform.
Active network equipment
Alcatel-Lucent Enterprise network equipment at every site, from the dispatch centre to the substations.
A single whole
All sites, from the dispatch centre to the substations, are connected into one system with shared operating logic.
Result
One system for the entire network
No single point of failure
Every critical component has a backup. The system keeps running even if any part of it fails.
All sites on one system
The dispatch centre and all substations communicate through a single, centrally managed platform.
Recording in line with regulations
All dispatch calls are automatically recorded and stored, without exception.
