Cornet Technology SwitchEdge Achieves Interoperability with Teradyne's Celerity; Combined Capabilities Enable an Open DSL Test Solution.

Business/Technology Editors

WASHINGTON--(BUSINESS WIRE)--Oct. 30, 2000

Cornet Technology, Inc. (CTI), an industry leader in providing physical layer test access and switching products for the enterprise and telecommunications markets and the Broadband Test Division of Teradyne, Inc. (NYSE: TER), a developer of state-of-the art broadband testing capabilities for DSL service providers, announced that they have successfully completed interoperability testing between CTI's SwitchEdge DSL test access switch and Teradyne's Celerity(TM) DSL test system.

SwitchEdge's interoperability with Celerity was proven earlier this year at Teradyne's CableFarm - a state-of-the-art access network test facility. The systems were tested against an array of physical line conditions, including North American and European loop models, to ensure product performance in actual network deployments.

The interoperability between CTI's SwitchEdge solution and Teradyne's Celerity system provides an integrated approach to remote testing, loop management, and provisioning of DSL loops to enable more rapid deployment of broadband services. Bringing service to market swiftly, with a minimum of field dispatches, gives service providers a competitive edge.

"Cornet Technology is focused on providing the most open DSL test access solution on the market today," said Sant Gupta, CTI's vice president of Sales and Marketing for North America. "The result of the interoperability tests with Teradyne's Celerity DSL test system reinforces our vision to provide customers with the widest choice in their test access solutions."

"By working with Cornet Technology, we were able to successfully prove the performance of the test system through the loop management access switch," said Chris Barton, Celerity Product Manager. "This enables us to meet service providers' needs for a cost-effective test and management solution to support their DSL rollout and customer base."

SwitchEdge, CTI's open-platform test access and monitoring family of switches, is designed to simplify loop management by enabling technicians to remotely access loops for testing, monitoring, or service changes without having to initiate a truck roll. SwitchEdge strikes the right balance between cost and functionality by offering a choice in configuration. Whether the requirement is for test access only or a more complete cross-connection solution, SwitchEdge addresses the service provider's needs. Its design permits the mixing of functionality within the same chassis to match a diversity of service offerings. With test access solutions starting as low as $20 per loop, the SwitchEdge family offers an affordable solution for any stage of DSL deployments.

Celerity performs layer 1 loop qualification, provisioning, and service assurance testing, enabling DSL service providers to accurately mass qualify, provision, and maintain DSL loops. The technology is both scalable and adaptable to multiple DSL technologies. Therefore, local exchange carriers can deploy DSL lines much faster, thereby increasing the total installation and service take-up rate and reducing overall provisioning costs.
