SAN JOSE, Calif., April 18, 2002 - Cisco Systems, Inc. (NASDAQ:CSCO) today announced that its carrier-class uBR10012 Cable Modem Termination System (CMTS) has received qualification for Data-Over-Cable Service Interface Specification (DOCSISTM) 1.1, following closely on the heels of the recent qualification of the Cisco uBR7246VXR. With this qualification Cisco becomes the only company with multiple Layer 3 DOCSIS 1.1 qualified CMTS systems.

"The DOCSIS 1.1 qualification process is a critical part of the industry's progress toward enabling the support of advanced IP services such as VoIP," said Carson Chen, vice president of Cisco's cable business unit. "The DOCSIS 1.1 qualification of the uBR7246VXR CMTS router and now the uBR10012 helps our cable customers to feel confident that their investment in existing and future network and service deployments can be optimized."

The Cisco uBR10012 combines the revenue-generating features and stability of the market-leading Cisco uBR7200 Series Universal Broadband router with an architecture that is optimized for aggregation and scaling. Cisco was the first cable router vendor to combine IP routing and intelligence with the DOCSIS standard. Since the first Cisco CMTS router was DOCSIS 1.0 qualified by CableLabs. in 1999, Cisco has delivered over 250,000 upstream ports to MSOs around the world. All deployed Cisco uBR7200 Series and uBR10012 CMTSs can be upgraded to 1.1 via a software upgrade.

DOCSIS 1.1 includes the features and capabilities that will enable cable providers to deliver and support advanced services such as primary line voice, residential high-speed data, QoS-based service tiers and commercial services.
