Business Wire, June 17, 2004

SANTA CLARA, Calif. -- Atrica's Carrier-class Optical Ethernet Systems a Key Part of the Metro Ethernet Network Protection Focus Area

In a demonstration of its commitment to advancing the state of metro Ethernet technology and enabling interoperability among providers of metro Ethernet equipment and services, Optical Ethernet solution provider Atrica(TM) today announced its participation in the Metro Ethernet Forum's (MEF) SUPERCOMM SUPERDemo technical interoperability showcase. Atrica's Carrier-class Optical Ethernet Systems - which combine the low cost, proven scalability, management ease and ubiquity of Ethernet technology with critical Carrier-class features - will play a key role in the Metro Ethernet Network Protection Focus Area.

The SUPERDemo will take place in booth #20736 at the McCormick Place Conference Center in Chicago, Illinois, June 22-24. A technical interoperability demonstration of key building blocks which carriers will use to deploy metro Ethernet services, the SUPERDemo will actively demonstrate the implementation of six different MEF Technology Focus Areas - all critical to carriers as they deploy Ethernet in their metro networks. The Technology Focus Areas include Metro Ethernet Network Protection, Ethernet User Network Interface (UNI), Ethernet Services, Circuit Emulation over Ethernet, Ethernet Traffic Management, and Test and Service Assurance.

A founding member of the MEF, Atrica fully supports the MEF's activities and is compliant with the E-Line and E-LAN services defined by the MEF.

"Atrica's mission is to give today's service providers the clear cost-saving and service-enabling benefits of Optical Ethernet technology, while ensuring they enjoy Carrier-class features such as guaranteed service level agreements (SLAs), sub-50 millisecond resiliency, integration with circuit switched networks, Ethernet Circuit Emulation Services (CES) for support of TDM traffic, and point-and-click OAM&P," said Nan Chen, vice president of marketing for Atrica and founding president and Board member of the Metro Ethernet Forum. "We are proud to be working with other industry leaders in the MEF to develop the technical specifications that will allow carriers to roll out robust metro Ethernet service programs quickly and cost-effectively."
