Business Editors/High-Tech Writers

PALO ALTO, Calif.--(BUSINESS WIRE)--Dec. 2, 2003

Copper Mountain Networks, Inc. (Nasdaq:CMTN), a leading provider of intelligent broadband access solutions, today announced the acceptance and official listing of the VantEdge(TM) Access BRAS by the United States Department of Agriculture's Rural Utilities Service (RUS).

RUS provides rural telecommunications companies and Independent Operating Companies (IOCs) with low interest financing for the purchase of telecommunications equipment that has met the demanding RUS standards for proven deployments, performance and reliability. On January 29, 2003, Secretary of Agriculture Ann Veneman announced the new Rural Broadband Loan and Loan Guarantee Program. For FY 2003, RUS has made available $1.4 billion in loans and loan guarantees to provide broadband services in rural communities.

Completing the RUS approval process offers IOCs significant financial assistance for the purchase and deployment of the VantEdge Access BRAS, which is listed in "Section 6 -- Transmission and Central Office Equipment." The listing can be found on the RUS web site under transport equipment at http://www.usda.gov/rus/telecom/materials/sec-6_loma.htm.

"The RUS financing program is an important source of financial and product validation assistance to rural telecommunications providers," said Mark Tiedeman, vice president of Product Management. "RUS acceptance makes the VantEdge available to IOCs under attractive financial terms, enabling them to deploy a highly versatile broadband access solution that addresses a wide variety of scalability and advanced services challenges in rural service provider networks."

The VantEdge Access BRAS is purpose-built as a powerful, yet highly cost-effective, multi-purpose platform that addresses three key IOC applications:

1. Subscriber Management Upgrade -- Many legacy Subscriber Management System devices are reaching exhaustion or are being discontinued with no viable upgrade path from the incumbent vendor. The VantEdge provides up to a 10x performance improvement, carrier class redundancy and management, native ATM switching, and advanced networking and QoS capabilities.

2. Remote Terminal (RT) Aggregation -- DSL growth is quickly occurring in DSL-enabled RTs. The VantEdge offers a highly cost-effective RT aggregation solution at a substantially lower cost than ATM switch/mux solutions while also enabling advanced services.

3. Enabling "Triple Play" Services -- Many IOCs want to offer a suite of broadband services including Internet, video, gaming, tiered services, dynamic bandwidth management (e.g., "Turbo button") and packet voice. The VantEdge's advanced multi-layer networking, QoS and management capabilities enable the "triple play" while preserving investment in existing equipment.
