Sonus Networks (News - Alert), a provider of IP communications infrastructure, today said that it has been selected by COLT (News - Alert) to deliver the core IP-voice infrastructure for the next phase of COLT's next-generation network (NGN) deployment.

 

COLT is a provider of data, voice and managed services to business and governments, reportedly serving 100 cities in 13 countries across Europe.

 

Sonus Networks officials said that COLT is deploying a complete edge to edge Sonus IP-based session control network with gateways in six major European cities. The solution includes centralized routing, and session border security for IP access and peering.

 

The network is currently operational in London, Frankfurt and Paris. By the end of summer 2008, the network is expected to extend to Zurich, Milan and Madrid, according to officials.

 

Officials pointed out that COLT will deploy the complete Sonus solution, including the ASX Access Server, GSX9000, the Network Border Switch (NBS), PSX Call Routing Server, SGX Signaling Gateway (News - Alert), and the Sonus Insight Management System.

 

Dr. Alireza Mahmoodshahi, CTO at COLT, said that his company selected Sonus Networks following a “rigorous and extensive” testing and review process, adding “We found that Sonus was the best partner for the session control technology which is robust, scalable and interoperable with our existing networks.”

 

Tony Morrish, vice president for EMEA at Sonus Networks, stated that COLT is one of Europe's premier carriers for business subscribers, and their decision validates the value Sonus delivers with the integrated solutions for the core network, subscriber services and edge security.

 

He also said that by deploying a Sonus-built network in Europe, COLT will be able to offer its customers a range of “innovative” applications and in addition will be able to “dramatically drive down the costs of maintaining its legacy equipment, making its business more resource efficient.”

 

Last week, PTV Telecom, a provider of voice, video and data over cable, said that it has selected Sonus Networks to replace its existing infrastructure with a PacketCable-compliant next generation network to offer business and residential services to customers in five major cities across Spain.
