TTNC's main network, telephone numbers and call services are operated via a Cluster of 4 Redundant Switches in Telehouse, London, the UK's premier Network Operations Centre (NOC).
If a switch fails, the calls that were going to that switch will be instantly routed into a different switch until such time as the failing switch is recovered.
TTNC always maintains enough spare capacity on each switch to cover such eventualities and therefore minimise and prevent any disruption to services.
By placing our main network in Telehouse, we have ensured that we have virtually unlimited capacity and access to the worlds leading Telecom Carriers and to the internet. This enables us to terminate and originate both UK and international call traffic at some of the best prices available in the UK telecoms market.
Our services run on a "Next Generation Network" (NGN) allowing us to support traditional PSTN voice services, intelligent Network Services and Voice over IP services.
Our voice network combines both PSTN and IP technology and has multiple connections to Top Tier Carriers, including 15 separate full Interconnects with BT in London and 10 separate full Interconnects with BT in Bristol.
Our IP Network has multiple Tier 1 Transit Suppliers as well as peering at LINX (London Internet Exchange).
Wherever feasible, there is always back up options such as multiple carrier choices, multiple routers and multiple equipment locations.
Redundancy is the most critical aspect of any Telecom or IP based service and TTNC's infrastructure is designed with no single point of failure and meets the highest industry standards.
Every link in the network has a backup link, if any link fails then an internal routing protocol re-routes the calls over a backup link in seconds.
All critical systems including database servers are configured in active/standby pairs and clusters for immediate and stateful failover in the event of an active system failure.
Services are operated on clusters of Switches and Servers to mitigate the risk of hardware failures, every network has a minimum of two Cisco routers.
In case of complete outage in one of our NOC's, all call traffic would be immediately re-routed to another NOC.
Two geographically separate Network Operation Centre's (NOC's) located in London and Bristol.
