Nortel Delivers Voice over IP Solutions with Strategic Alliance Partners Calix, KEYMILE

TORONTO--(CCNMatthews - Jun 7, 2005) -

New Solutions Designed to Help Service Providers Reduce Complexity, Costs of Transition to Next Generation Networks

Nortel (NYSE:NT)(TSX:NT) and strategic alliance partners Calix and KEYMILE are introducing new voice gateway functionality to their broadband access products that provide compatibility with Nortel's Voice over IP (VoIP) solution. This new functionality helps service providers simplify and reduce the cost of their next generation networks by providing them with compact-line gateways that convert voice traffic from a circuit-based orientation to a packet-based implementation. The products are compatible with VoIP standards and have been tested with Nortel's softswitch solutions.

"Nortel's service provider customers are increasingly asking for integrated solutions that help simplify network deployment, drive down cost, and position their networks for the next generation of services," said Walt Megura, general manager, Broadband Networks, Nortel. "Our work with Calix and KEYMILE underscores Nortel's commitment to addressing these needs, and is a significant step toward providing next generation VoIP solutions."

The Calix C7 multiservice access platform, targeted at the North American (ANSI) market, as well as the KEYMILE UMUX multi-service access platform, intended for ETSI market deployments, have achieved H.248-based VoIP interworking with Nortel's Communication Server (CS) 2000. Successful integration and testing of these products helps position service providers to packetize their voice traffic using the VoIP gateway in the Calix or KEYMILE platforms and to gain the added benefit of using lower cost Ethernet connections to transport voice calls back to the central office. The adoption of an end-to-end Nortel VoIP solution can enable operational savings of up to 30 percent versus traditional circuit-switched voice networks, based on Nortel estimates.

This new end-to-end solution helps service providers gain the benefit of a smoother and more seamless transition path as they start to evolve their networks from circuit to packet orientation. Both the Calix C7 and KEYMILE UMUX are designed to require only the addition of a new VoIP gateway card to the existing shelf to enable the H.248 functionality, which improves investment protection and provides the flexibility for service providers to upgrade their networks at their own pace. In addition, the solution is designed to enable the provider's current voice subscribers to seamlessly transition to the new network by preserving their toll-grade voice quality without requiring change or replacement of their existing phones.

"With interoperability between leading suppliers such as Nortel and Calix, service providers are able to rapidly and confidently migrate to VOIP services," said Tom Corker, vice president and general manager, Access Products, Calix. "This, in turn, better positions them to reduce the cost of operations in delivering traditional voice services as they evolve their networks to IP."

"Through our investment in an extensive joint testing program, we enable operators to confidently move voice traffic to IP, hence allowing the rapid introduction of new services and immediate cost reductions," said Sameer Sant, director, corporate strategy, KEYMILE. "KEYMILE looks forward to building upon our long standing market success with Nortel by enabling a seamless NGN transition for operators globally."

With approximately 55 customers with live packet deployments, Nortel's CS 2000 softswitch has one of the industry's largest existing customer bases. These customers can now leverage the Calix C7 or KEYMILE UMUX as a cost-effective compact-line gateway as they continue their evolution to packet networks.

The Calix C7 has extended its network transformation versatility with new H.248 gateway functionality via a VoIP Resource (VIPR) card that will be generally available in the fall of 2005. Service providers can deploy the Calix C7 today and deliver traditional voice services utilizing standard voice interfaces across a traditional TDM network. When a service provider is ready to evolve to a Nortel softswitch architecture, the Calix C7 is also ready to evolve as it merely requires the addition of a VIPR card to enable H.248 for all existing voice lines.

The KEYMILE UMUX Access Gateway introduced H.248 functionality in the second half of 2004, and has successfully concluded interoperability testing with the Nortel CS 2000. Several service providers are testing the interworking solution from Nortel and KEYMILE. The UMUX supports a wide range of technologies and service options from a single access platform designed to be installed within local exchanges and outside plant enclosures, including street cabinets.

Nortel is a leader in the carrier voice over IP market. For the entire year 2004 and the first quarter of 2005, Nortel ranked #1 globally in carrier packet voice and softswitch revenue, according to Synergy Research Group (SRG). Over the past year, Nortel has announced wins with major carriers including Verizon, BellSouth, Bell Canada and Charter Communications in North America; Chungwha Telecom and Dacom in Asia Pacific; Cable & Wireless and Telefonica in the Caribbean and Latin America; and THUS in Europe.
