JDSU Combines Industry-Leading NetComplete System and Software Solution with AT&T Broadband Technology Expertise to Lower Costs and Improve Service Levels of Broadband Networks

San Jose, California, February 16, 2005 — JDSU announced today a licensing agreement with AT&T Knowledge Ventures, the intellectual property arm of AT&T Inc. (NYSE:T), to expand its management solution with new NetComplete Broadband Tools featuring broadband capacity and performance management network technology developed by the AT&T family of companies.  

JDSU’s NetComplete Consumer Broadband Tools establishes a best-in-class software package to help service providers support improved capacity management, lower costs and reduce trouble tickets. It also helps to accelerate revenue for their current consumer broadband offerings and for new, next-generation services deployment.

The JDSU solution will now be enhanced with the Broadband Tools Suite, a proven software management tool developed by the AT&T family of companies for its own broadband network. The AT&T technology is designed to enable engineers and operations personnel to improve broadband network management and performance.

“AT&T is the leading DSL broadband provider in the United States. Licensing of AT&T technology by JDSU should accelerate innovation in the service assurance market for the NetComplete platform," said Patrick Kelly, senior analyst and co-founder of OSS Observer. "This combination has the potential to benefit all xDSL providers not only to maintain but also improve their service offerings."

The JDSU NetComplete Consumer BroadBand Tools solution brings together a suite of powerful software tools in a framework that allows a provider to deploy the solution quickly and efficiently. It adds to NetComplete’s existing suite of powerful capabilities, including NetOptimize for capacity planning and active/passive performance management and NetAnalyst for active management of probe-based testing.

“JDSU is proud to bring to market innovative broadband software solutions to service providers around the world,” said Helmut Berg, senior vice president of JDSU’s Communications Test and Measurement Group. “The licensing agreement with AT&T Knowledge Ventures will allow JDSU to offer any xDSL-based service provider the benefits experienced through using AT&T technology, including efficient capacity management, reduced trouble report rates, improved customer experience, and decreased capital and operational costs in supporting a broadband network.”

“Our efforts to optimize the DSL services we offer on more than 6.9 million lines have led our company to develop some of the most powerful analytics and optimization tools in the industry,” said Abha Divine, president of AT&T Knowledge Ventures.  “Through JDSU and its NetComplete Consumer Broadband Tools, we are pleased to make available our experience and tools to enable other providers to enjoy successful broadband deployments, ultimately raising the success of the entire DSL industry.”
