Cable broadband systems operator Suddenlink Communications announced on Wednesday that it be using a VoIP system from Nortel to provide a suite of telephone and multimedia services to its customers. The system is comprised of network design, as well as integration, management and maintenance services from the Nortel Global Services portfolio.   The move will enable Suddenlink (formerly Cebridge Connections) to expand its telephony services with the acquisition of cable systems from Cox Communications and Charter Communications.   According to Suddenlink, this new network will provide VoIP-based telephony services to the company`s national customer base from California to North Carolina, and will include conversion of approximately 30,000 telephony subscribers acquired from Cox.   “With Suddenlink`s pending integration of several networks, it is critical that our new VoIP network integrate seamlessly with equipment from multiple vendors,” said Suddenlink senior vice president, Engineering Terry Cordova in a statement. “Nortel’s services and expertise, the proven interoperability of its VoIP solution and its IMS roadmap give us confidence that they can uniquely help our company launch and maintain a new VoIP service.”   “Nortel has earned a reputation as a leader in simplifying the deployment of VoIP services for our cable customers,” said Tom Buttermore, vice president and general manager, Global Cable Solutions, Nortel. “Our track record for producing quality products and contributing high-caliber expertise has made Nortel a primary choice for companies like Suddenlink looking to introduce advanced telephony to both residential and business markets.”   The companies expect to begin deployment later this year, with anticipated completion by the end of 2007.
