Sonus Networks and Camiant Deliver IP Multimedia Services to the Cable Industry
Jun 18, 2008 (08:06 AM EDT)

WESTFORD, Mass., June 18 /PRNewswire-FirstCall/ -- Sonus Networks , a market leader in IP communications infrastructure, today announced the completion of interoperability testing of its PacketCable(TM) 2.0 compliant portfolio of products with Camiant, Inc., the leading provider of policy control and application assurance technology, and its PacketCable Multimedia (PCMM) compliant policy server. The integrated solution will enable cable providers to more rapidly migrate their networks -- from the basic triple play of voice, video and data to next generation services. For cable customers, this will mean a higher quality of service where voice communications are not disrupted by the demands of other high bandwidth services such as file transfers, IPTV or video sharing.

Broadband Trends reports that over 13 million U.S. households received their telephone service from a cable operator at the end of 2007, a 68% increase from 2006. As many of these subscribers already have both Internet and TV, policy management to ensure that each service is delivered without interruption is a critical part of existing and future deployments of voice and video services. Now, cable providers are turning to the IP Multimedia System (IMS) to offer multi-media services that include video and mobile devices.

"The cable industry has a history of being aggressive; first deploying high-speed Internet services, then adding digital voice for a triple play and now offering new services with PacketCable 2.0. Camiant is an established leader in policy control and Sonus recognized the importance of partnering with Camiant so that cable providers can integrate multiple services seamlessly," said Michael Rubin, vice president of Cable & Wireline Solutions at Sonus Networks. "To win subscribers in this competitive market, the cable industry needs to have the tools to innovate successfully and deliver the demands of today's customers, while investing in and wisely managing their networks for tomorrow."

"Camiant believes that a superior policy management solution assures a superior subscriber experience," said Susie Riley, CTO and Founder of Camiant. "As MSOs add new services and migrate to IMS, policy becomes even more important as the number of services offered through the same pipe increases. Our partnership with Sonus means that our cable customers can seamlessly leverage their existing deployments of Camiant's policy server with Sonus' PacketCable 2.0 infrastructure to move forward confidently with next-generation voice and multimedia deployments today."

Sonus Networks' solutions are deployed in six of the world's top ten telecommunication providers and at cable operators in the Americas, Europe and Japan. Sonus offers a comprehensive IMS solution that addresses the full range of carrier applications, including residential and business voice services. The tested Sonus/Camiant integration includes support for existing deployments and it is designed to facilitate the evolution of cable providers'

networks to IMS -- the industry blueprint for a true all-IP network with advanced applications. Testing included:

-- Sonus ASX(TM) Call Server for residential and business telephony services supporting DQOS and 3GPP compliant ISC interface;

-- Sonus SRX providing the industries most advanced platform for the 3GPP Call / Session Control Function with 3GPP and PacketCable compliant Rx interface;

-- Sonus NBS providing advanced security and media control in conjunction with a 3GPP compliant P-CSCF and the IMS Border elements;

-- Sonus IMX providing a PacketCable compliant service development platform that allows operators to create PacketCable Multimedia compliant enabled applications that combine the power of SIP, Web 2.0 with enablers such as presence and messaging.

Camiant's Multimedia Policy Engine (MPE) enables real-time quality of service control for VoIP calls and other services over cable's DOCSIS(R) high-speed data network. The software-based solution allows multiple system operators (MSOs) to rapidly deploy IP voice based services for residential and business customers. Camiant's MPE has already been deployed at several of the largest cable operators worldwide.
