PALO ALTO, Calif.--(BUSINESS WIRE)--Aug. 5, 2003

Fills Price/Performance Gap Between Legacy

Subscriber Management Devices and Edge Routers

Copper Mountain Networks, Inc. (Nasdaq:CMTN), a leading provider of intelligent broadband access solutions, today announced the VantEdge Subscriber Management Switch (SMX) Package -- a subscriber management application for the field-proven VantEdge Access BRAS. The high performance VantEdge SMX package offers service providers more than a ten fold improvement in performance and active subscriber capacity compared to the most widely deployed subscriber management devices -- along with improved reliability, advanced features and comprehensive network management -- for a fraction of the cost of most edge routers.

Copper Mountain designed the VantEdge platform to cost-effectively address a range of networking applications. In the first such application, as an Access Broadband Remote Access Server (BRAS), VantEdge has gained a great deal of momentum and is in trials with several large carriers worldwide. Subscriber management is the second major application targeted by the VantEdge and represents an attractive market opportunity given the large installed base of legacy subscriber management devices, many of which have reached -- or soon will reach -- capacity limitations.

"The introduction of the VantEdge SMX package is timely, as today's carriers are quickly running out of subscriber management capacity and they are finding no rational upgrade options from a price/performance standpoint," said Keith Higgins, Vice President of Marketing for Copper Mountain Networks. "Many subscriber management devices are being discontinued, and the 'upgrade paths' being offered by many vendors requires service providers to overspend on expensive, edge router-based devices that are much too large, complex and costly for the application at hand. The VantEdge is the ideal migration option."

Key features of the VantEdge SMX package include:

-- 10x performance improvement over most installed subscriber

management devices

-- Cost-effective upgrade path to increase active subscriber

management capacity

-- Carrier class reliability and redundancy

-- Advanced networking capabilities, including

auto-configuration, dynamic bandwidth on demand (BoD) and

Hierarchical Virtual Port Scheduling (HVPS)

-- Comprehensive, integrated range of multi-layer QoS features

for advanced applications such as video, gaming and packet

voice

-- Native ATM switching and Traffic Management 4.1 support

-- Scalable network management with comprehensive graphical user

interface (GUI)

-- Broad range of ATM, Ethernet and Gigabit Ethernet interfaces

"We had simply outgrown our current subscriber management solution, and we needed a host of new networking features to deliver additional premium broadband services," said Hans Nilsson, President/CEO at Bruce Municipal Telephone System "The VantEdge is unique in offering a cost-effective, high performance, carrier class subscriber management solution plus a comprehensive suite of networking capabilities for advanced services in a single platform."

The VantEdge SMX package is available immediately. For more information, contact your Copper Mountain sales representative or visit www.coppermountain.com.
