New Branch Office Expands Broadband Networking Solutions Provider's

Presence in Asian/Pacific Market

Copper Mountain Networks, Inc. (Nasdaq:CMTN), a provider of Digital Subscriber Line (DSL) solutions for business and residential users, today announced that it has opened an international office in Hong Kong. Copper Mountain is a market leader in multi-tenant unit (MTU) broadband access systems and Copper Mountain's CopperEdge(R) and OnPrem(TM) DSL concentrators are ideally suited to meet the broadband access needs of this dynamic region. The Hong Kong office is headed by regional sales manager Felix Tsim, who is representing Copper Mountain's complete line of CopperEdge and OnPrem DSL concentrators, as well as CopperRocket(R) and CopperCompatible(TM) customer premise equipment (CPE), to established and new broadband service providers in Hong Kong, China, and Taiwan. Copper Mountain opened its regional headquarters in Singapore last year and serves the European, Middle Eastern, and African markets from its Amsterdam office.

Copper Mountain's solutions support a full range of DSL services for customers and business users, and are equipped with Copper Mountain's Internet Protocol (IP) service intelligence (IP IQ(TM)), which allows providers to scale value-added broadband services without the virtual circuit proliferation problems associated with Asynchronous Transfer Mode (ATM)-based solutions. Copper Mountain's Copper Edge DSL platform supports Asymmetric DSL (ADSL) variants, such as Full-Rate ADSL and G.lite, that offer the fast downstream speeds required by consumers for Internet access. The company's CopperEdge and OnPrem DSL platforms also support symmetric DSL (SDSL) which provides both high upstream and downstream connectivity speeds for business users. Copper Mountain's DSL equipment is used by leading service providers in many of the world's largest telecommunications networks to cost-effectively deliver a broad service menu, including Internet access, corporate virtual private networks (VPNs), Voice over DSL (VoDSL), wholesale DSL, and Frame Relay over DSL (FRoDSL), maximizing revenue per copper pair.

Copper Mountain solutions are currently being deployed in the Asia/Pacific region by Pacific Internet and TTAsia. Singapore-based Pacific Internet last year selected Copper Mountain's CopperEdge DSL concentrators to deliver DSL broadband services to business customers in Singapore, China (Hong Kong), the Philippines, Australia, India, and Thailand. TTAsia, a Corporate Access (Hong Kong) Ltd. company, recently announced that it has standardized on Copper Mountain's carrier-class CopperEdge and OnPrem DSL concentrators to deploy in-building DSL services to residential and business customers in India, Thailand, Malaysia, and China.

"The market for broadband services is growing rapidly in the Asia/Pacific region, and providers there require networking solutions that enable them to cost-effectively provision multiple services and scale these services quickly and easily," said Rick Gilbert, president and chief executive officer of Copper Mountain Networks. "Copper Mountain has the solutions providers require, and with Felix Tsim representing us in Hong Kong, our ability to bring these solutions to the Asia/Pacific market is significantly enhanced. Felix is remarkably well qualified to represent Copper Mountain in Hong Kong, Mainland China, and Taiwan. He has extensive experience in the region's broadband industry and an in-depth understanding of the needs of both end-users and broadband service providers. We're very pleased to have him lead this office."

"DSL deployment is ramping up in the Asia/Pacific market, and expanding especially rapidly in China," said James Person, Copper Mountain's director of international sales. "The opening of our new Hong Kong office under the able direction of Felix Tsim further strengthens Copper Mountain's ability to deliver world-class solutions and world-class customer support throughout the region."

"Copper Mountain is an industry leader in developing and delivering highly reliable and practical broadband-access solutions," added Mr. Tsim. "Copper Mountain's solutions enable providers to operate at a high level of cost-efficiency in today's networking environment, where ATM solutions are prevalent, and migrate seamlessly to the networking environment of the future, where IP solutions will dominate. I am excited to be associated with such a future-oriented company, and I look forward to representing Copper Mountain to customers in Hong Kong, Mainland China, and Taiwan."
