ETHERNET ENHANCEMENTS FROM NORTEL ENABLE SERVICE PROVIDERS TO COST-EFFECTIVELY OFFER SCALEABLE TRIPLE PLAY SERVICES

Metro Ethernet Routing Switch Enhancements, Metro Ethernet Services Unit 1850 Introduced

Nortel (NYSE:NT) (TSX:NT) today introduced new products and functionality for its Metro Ethernet portfolio that are designed to eliminate technical barriers and high costs service providers face in deploying Ethernet-based triple-play services -- voice, video, data -- to residential and enterprise customers in metro and national markets. Paired with the Nortel Ultra Broadband Solution portfolio, these products offer a powerful end-to-end solution for service providers.

Enhancements to the Nortel Metro Ethernet Routing Switch (ERS) 8600 and the addition of the Nortel Metro Ethernet Services Unit (ESU) 1850 are designed to allow delivery of voice, video or data over any port, as well as the ability to securely separate end-user traffic for over 4,000 subscribers on each and every port.

Combined with new Internet Protocol (IP) multicast capabilities also now available, they provide a platform capable of supporting delivery of IPTV, VoIP and Internet access services to tens of thousands of residential and enterprise subscribers using a single Ethernet infrastructure.

Danish utility company EnergiMidt recently began deployment of a Nortel ultra broadband solution to provide triple-play services to its customers across Denmark.

The Metro ERS 8600 and the new Ethernet Services Unit 1850 are also deployed in the network to provide aggregation and switching of the Ethernet infrastructure, working in conjunction with the Broadband Access Services Gateway 7710 Optical Line Terminal for residential delivery of triple-play services using Passive Optical Networking (PON).

"Our services strategy required that we deploy a network that is able to support a traditional triple-play offering today while providing the flexibility and scalability to enable next generation IP-based offerings in the future," said Martin Romvig, general manager, EnergiMidt Broadband.

"Providing a cost competitive offering is critical for our market penetration plans, and the unequalled support of Ethernet services in the Nortel Metro Ethernet solution made it a vital part of allowing us to achieve these service goals."

While a variety of Ethernet services have been gaining in popularity in recent years, the costs associated with deploying services to a broad customer base over a resilient Ethernet infrastructure have hindered service provider build outs.

Service providers have been faced with a difficult choice between service quality and network cost.

The new Nortel enhancements are designed to deliver a cost-effective Ethernet infrastructure for services at the edge of the network that maintains the carrier qualities expected by enterprises worldwide.

Nortel studies and actual customer deployments have demonstrated potential savings of 25 to 50 percent over conventional Ethernet or TDM networks.

"Metro Ethernet is one of the fastest growing opportunities within wireline telecom, driven in part by emerging broadband applications such as IPTV and video on demand," said Sterling Perrin, research manager, Optical Networks, IDC.

"IDC forecasts that the market for metro Ethernet equipment will increase at a 26 percent compound annual growth rate to reach (US)$5.5 billion by 2009.

Improvements to equipment to enable these next generation applications reliably and at lower costs are critical to the success of both metro Ethernet equipment vendors and their service provider customers."

The Nortel Metro Ethernet solution is designed to help service providers drive greatly reduced costs by eliminating the need to build separate Ethernet infrastructure for unicast and multicast services. The Nortel Metro Ethernet solution can handle multicast (broadcast video) and unicast (voice over IP, video on demand) traffic over a single, converged Ethernet infrastructure or in combination with PON or xDSL implementations.

The Metro ESU 1850, which complements the existing Metro ESU 1800, is capable of supporting up to 12 gigabit Ethernet lines over copper or optical infrastructure.

The Metro ESU 1850 provides low-cost, fully redundant backhaul of next generation DSL services, wireless access services and the like.

Up to 14 Metro ESUs may be arranged in a ring topology extending from the Metro ERS 8600 to offer service providers a massively scalable Ethernet infrastructure that can support a variety of services such as Ethernet VPNs, IP-based triple-play, and 3G wireless backhaul.

Nortel Metro Ethernet products are designed for easy set up and use and are fully manageable (in or out of band) with SNMP applications such as the Nortel Product Services Provisioning and Multiservice Data Manager tools.

Significant automation of the provisioning and configuration process enables quicker service activation and error-free service adjustments.

The Nortel Ethernet Routing Switch 8600 delivers high-density, high-performance Layer 2-7 switching, routing and traffic classification.

More than 35,000 units and 187,000 service cards have been shipped to service provider and enterprise customers around the world.
