Dacom Corporation, a leading Korean provider of telephony, Internet and data communications services, has selected Nortel Networks (NYSE:NT)(TSX:NT) to provide a next generation network (NGN) voice over IP (Internet Protocol) and multimedia solution. The Dacom contract was awarded to Nortel Networks through its Korea channel distributor, ITIAN Corporation.

Nortel Networks will supply Dacom with a comprehensive voice over IP solution that includes products from Nortel Networks multimedia communications and Nortel Networks Succession voice over IP portfolios.

"As a global leader in voice over IP and multimedia services, Nortel Networks is delighted to be working with Dacom to provide Korea's first carrier-grade NGN services offering," said Soo-Jin Chung, managing director, Korea, Nortel Networks. "This contract will position Dacom to provide enhanced services for their customers, while helping to drive enhanced network efficiency and reduced operating costs."

"Nortel Networks has been gaining significant traction with its voice over IP and Multimedia Communications portfolio throughout Asia," said Gord Quinn, general manager, Multimedia Communications, Nortel Networks. "Dacom clearly recognizes that deploying a next generation network will help position them to drive new revenue opportunities while fully leveraging existing network investments."

Dacom's NGN network will be based on Nortel Networks Succession Communication Server (CS) 2000-Compact superclass softswitch and Multimedia Communication Server (MCS) 5200, which enables delivery of new, revenue-generating services at lower operational costs. These products will enable Dacom to offer customers enhanced communications services that will create simplified communications, enhanced mobility and increased productivity.

Succession CS 2000 is a superclass softswitch that can position service providers to economically serve business, residential and transit markets with a comprehensive set of services designed to address opportunities for generating new revenues. A superclass softswitch provides true service provider circuit-to-packet migration, including local, tandem and long distance capability on a single platform, full business and residential telephony service sets, and carrier-grade reliability and scalability. It also provides regulatory features such as lawful intercept and number portability.

Nortel Networks MCS 5200 is a carrier-grade, SIP-based media and applications server. Leveraging an open, standards-based architecture and commercially available hardware and software, it gives service providers the ability to offer advanced multimedia and collaboration applications to businesses and consumers.
