Siemens’ SURPASS Next-Generation IP-Based Softswitch Platform Helps Cablevision Reach One Million Voice Customers

Boca Raton, Fla, Jul 20, 2006, Siemens Communications Inc. today announced that its SURPASS next-generation Internet Protocol (IP)-based softswitch platform has helped its customer, Cablevision Systems Corporation, sign up one million subscribers to the company’s VoIP service, called Optimum Voice, in less than three years. Cablevision is the largest cable services provider in the greater New York area, with more than three million cable television customers.

Siemens’ SURPASS platform supports multiple network configurations and has the capacity to support up to 150,000 subscribers in a single softswitch. With rapid feature development capabilities, Cablevision has been able to deliver a rich and growing feature set to subscribers of its flat-rate $34.95 Optimum Voice service, including a web portal so customers can manage their accounts and features themselves. This offers users more control over their telephony services with greater convenience and less reliance on traditional customer service contacts and assistance.

Cablevision chose Siemens’ SURPASS platform in 2003 to help drive an aggressive deployment of Optimum Voice throughout its service area. The first major cable company to deploy VoIP across its entire service area, Cablevision continues to be an industry leader. With Siemens’ highly reliable SURPASS platform enabling Cablevision to deliver E911, one-third of the company’s cable television customers and more than half of its high-speed Internet customers have already chosen Optimum Voice.

“The strong response to Optimum Voice, a service powered and continually enhanced through reliable soft switching technology developed by Siemens, has positioned Cablevision to pursue its next major growth opportunity - providing Optimum for business voice and data services with the same level of value, reliability and performance to the hundreds of thousands of businesses in our service area,” said Tom Rutledge, Cablevision’s chief operating officer.

“Siemens congratulates Cablevision on reaching the one-million subscriber mark, which we consider a huge validation of our SURPASS VoIP platform,” said Harald Braun, president, Networks Division, Siemens Communications Inc. “We designed SURPASS to provide all types of network service providers with a platform that can enable them to drive feature-rich, differentiated services and the ability to grow those services with the quality, reliability and security their customers demand.”

In July 2006, Siemens reached the 5 million mark for licenses sold for its SURPASS softswitch, which has been deployed by other U.S. service providers, as well as by service providers across the globe. International customers include Shaw Cable in Canada, Multimedios in Mexico, and UPC, Com Hem, Casema and Essent in Europe.
