ORLANDO, Fla. – Nortel Government Solutions*, a U.S. company wholly owned by Nortel* [NYSE/TSX: NT], has unveiled a new unified communications platform designed specifically to meet the stringent security and service assurance requirements of the U.S. Department of Defense** (DoD) and other agencies of the U.S. Federal Government.

With a unified communications solution based on Nortel’s new Application Server 5300, defense and civilian government agencies can enhance productivity and speed decision-making by integrating voice, instant messaging, multimedia conferencing and presence services to reduce delays in connecting people and information. This solution also supports mobility, enabling remote and field personnel to benefit from the same services.

An open, SIP-based software product, Nortel’s Application Server 5300 will comply with federal IPv6** and DoD assured services requirements to enable secure, resilient VoIP and unified communications using commercial, off-the-shelf computing hardware. SIP is a next generation signaling protocol designed to accelerate delivery of new services, reduce costs and facilitate interoperability between vendors.

“Security and reliability are of paramount importance to government agencies, and in particular to the military,” said Chuck Saffell, chief executive officer of Nortel Government Solutions, which provides a variety of communications networking technologies and IT services for government organizations including the U.S. Social Security Administration, the U.S. Senate and the U.S. Department of Defense.

“We’re experts at developing highly secure, reliable and scaleable solutions that meet or exceed the most rigorous government requirements,” Saffell said. “With Application Server 5300, we have a solid platform based on proven Nortel technology that can help government agencies maintain high security and reliability while transforming their networks to VoIP and unified communications.”

Nortel Application Server 5300 will also support multi-level precedence and pre-emption, a DoD-compliant command and control mechanism that enables the most critical communications priority over existing calls.

Nortel Government Solutions is demonstrating Application Server 5300 at DISA (Defense Information Systems Agency) Customer Partnership Conference 2008** in Orlando, Fla. Initial availability with JITC** (Joint Interoperability Test Command) certification is planned for September 2008. IPv6 and DoD assured services compliance are anticipated in the first half of 2009 and will be available via software upgrade.
