WASHINGTON, D.C. -- Corrigent Systems, Inc. will conduct the industry’s first live demonstrations of SONET and Ethernet over a 10 Gbps Resilient Packet Ring (RPR) at the COMNET conference and expo, booth #544. Corrigent will demo its CM-100Ô RPR solution, which will be one of the first implementations to support the IEEE’s RPR standard.Revolutionary in its economics, Corrigent’s CM-100 offers a complete transport solution to carriers. Not only does it carry Ethernet traffic while transparently supporting the full range of existing TDM and SONET-based services at speeds of 10Gbps, but it does so for half the cost of alternative solutions.Corrigent’s innovative solution will demonstrate sub-50msec restoration time for both transparent high-speed SONET services and Gigabit Ethernet over RPR, utilizing the RPR MAC fast-protection mechanism. Integrated in the demonstration will be Corrigent’s CM-View™ Element Management System (EMS), demonstrating the rich service provisioning, fault management and performance monitoring capabilities of Corrigent’s TMN compliant solution. A local craft screen will demonstrate the TL-1 based management capabilities."Carriers are looking for solutions that economically combine the best of SONET and Ethernet to allow them to provide a competitive "one stop shop" for both circuit and packet services," said John Coons, vice president and chief analyst of optical networking.Corrigent Systems Inc.
