CHICAGO -- Corrigent Systems, a leading provider of packet-ADM (Add Drop Multiplexer) for next-generation transport networks, today announced that it will be demonstrating Resilient Packet Ring (RPR) protection switching, supporting the recently completed IEEE 802.17 standard. Corrigent's RPR sub-50msec protection switching will be demonstrated over a 10Gbps ring of its CM-100 Packet ADM as part of the Metro Ethernet Forum (MEF) live multi-vendor interoperability showcase at SUPERCOMM 2004 booth #20736.

This display is part of a larger demonstration by members of the MEF showing capabilities of the latest service provider equipment to support different aspects of Ethernet services delivery. Corrigent is supporting E-Line and E-LAN services as defined by the MEF and will show the ability to protect services from interruption in the event of physical disruption of the ring, in a manner compliant with the requirements outlined in the recently published MEF 2 technical specification: "Requirements and Framework for Ethernet Service Protection in Metro Ethernet Networks".

"Corrigent is pleased to show the capability of our Packet ADM equipment to provide the same level of protection for data as has traditionally been available in voice networks, all while supporting the IEEE 802.17 standard," said Leon Bruckman, Vice President and Chief Architect for Corrigent Systems and co-editor of the new IEEE standard. "We've been involved in creating the RPR standard for several years, and this demonstration is another important step in the acceptance of RPR as an essential ingredient in today's data-centric transport networks."
