Business Editors/High-Tech Writers

SAN JOSE, Calif.--(BUSINESS WIRE)--April 22, 2003

Corrigent Systems, a leading provider of packet-ADM (Add Drop Multiplexer) transport systems for metropolitan networks, today announced an agreement with Lucent Worldwide Services (NYSE:LU), whereby Lucent will provide installation and support for Corrigent's family of CM-100(TM) products. The agreement enables Corrigent to utilize Lucent's extensive team of installers to deploy and install Corrigent's CM-100 products into carrier networks. Lucent will provide services such as site surveys, equipment installation, and final acceptance testing so deployments of Corrigent's CM-100 products are more efficient.

"Lucent is a recognized leader in deploying, maintaining and installing some of the world's largest networks," said Nigel Cole, vice president of business development, Corrigent Systems. "Corrigent's agreement with Lucent widens the installation and support service options available to our customers with a world class, complete suite of support services for CM-100 deployments."

"We are delighted to partner with Corrigent Systems because we have a long history of supporting customers with multivendor networks," said David Dial, vice president of business development, Lucent Worldwide Services. "This opportunity is another way for us to support multivendor networking and we look forward to working with Corrigent in this area."

Corrigent's solution is optimized for today's metro networks. The CM-100 packet-ADM supports carriers that desire all mixes of Ethernet or legacy services either as part of a new deployment or by simply utilizing the spare capacity within their existing SONET/SDH networks.

By offering carriers a migration path, whereby past investment in SONET network capacity is maximized before moving to new construction, the CM-100 represents a highly efficient method to build multi-service (TDM/SONET/Ethernet) metro networks. Packet-based rings can first be provided in the network by utilizing spare SONET working or protection capacity. And, when additional bandwidth is needed, the CM-100 can be used for new SONET compatible multi-service networks. Furthermore, as Corrigent's solution utilizes SONET technologies, the CM-100 fits easily into today's existing SONET operational processes, while utilizing MPLS to realize dramatic operational cost savings.
