SAN JOSE, Calif., April 15, 2002 - Cisco Systems, Inc. (NASDAQ: CSCO) today announced that three of its products have been accepted for inclusion in CableLabs®' PacketCableTM Advanced Interoperability Test Network (AITN).

The Cisco uBR7246VXR router, as well as the Cisco AS5350 Media Gateway and its CSRC/BPR Provisioning Server will be installed in CableLabs' facility in Colorado and will facilitate the testing of components submitted for PacketCable certification and qualification. The uBR7246VXR is the only CMTS currently included in the Advanced Interoperability Test Network.

Built on top of the industry's DOCSISTM 1.1 (Data Over Cable Service Interface Specifications) cable modem infrastructure, PacketCable networks use Internet protocol (IP) technology as the basis for a cable architecture capable of delivering applications such as VoIP (Voice Over IP). The 1.0 release of the PacketCable specifications defines a complete architecture for offering primary-line telephony service to residential customers.

All three of the Cisco cable products were chosen because they are designed to support the latest advanced PacketCable features. They have all met criteria for interoperability with other systems such as call agents (or softswitches), voice-enabled cable-modems, and billing servers.

The uBR7246VXR was selected on the basis of its support for PacketCable features such as dynamic Quality of Service (DQoS), event messaging for billing, and security. The uBR7246VXR received DOCSIS 1.1 qualification in the latest CableLabs certification wave and is the only layer-three CMTS router that has received this designation.

"CableLabs has done an excellent job in establishing specifications for the cable industry and Cisco has been a pro-active advocate of that effort," said Carson Chen, vice president of Cisco's cable business unit. "The PacketCable initiative is a critical part of the cable specification process and Cisco looks forward to working alongside CableLabs to ensure the fulfillment of its potential."

Cable Television Laboratories, Inc. (CableLabs®) is the cable industry's specification setting and testing organization. PacketCable is a CableLabs®-led initiative developing interoperable interface specifications for delivering advanced real-time multimedia services over two-way cable plants. CableLabs has been conducting qualification testing of product based upon the PacketCable specifications since 2001. This testing ensures that products from various vendors meet the interface protocol requirements defined in the PacketCable architecture. While CableLabs has not qualified any PacketCable product to date, the AITN consists of vendors with the most advanced implementations of PacketCable specifications and is used for system interoperability testing.
