Market Momentum Continues with New Major European PTT Lab Trial

Copper Mountain Networks, Inc. (Nasdaq:CMTN), a leading provider of intelligent broadband access solutions, today announced that its new VantEdge(TM) Broadband Services Concentrator is commercially available for customer deployment, and that the first VantEdge revenue shipment will take place this month. In addition, the company announced that it has shipped a VantEdge to a large European Postal Telephone and Telegraph (PTT) for a lab trial, adding to the North American Incumbent Local Exchange Carrier (ILEC) and Inter-Exchange Carrier (IXC) trials already in progress.

As part of the process of reaching full commercial availability status, the VantEdge was recently certified for compliance with the Network Equipment Building System (NEBS) Level 3 standards, as well as other CE Mark, CSA, and FCC standards necessary for global deployment. The NEBS standards were developed to qualify equipment for deployment in telephone company central office buildings. By meeting the highest level of the NEBS standards, the VantEdge is suitable for deployment over the widest set of conditions. To achieve NEBS Level 3 compliance, the VantEdge successfully passed a series of demanding tests in which the VantEdge operated under a variety of environmental extremes, including fire, corrosion, air temperature/humidity/pressure, and simulated major earthquakes.

The VantEdge is the industry's first carrier-class platform purpose built for the central office (CO) to address broadband service providers' two most critical issues -- scalability and profitability. It supports multi-layer CO intelligence -- CO IQ(TM) -- that enables copper-based broadband providers to slash costs associated with scaling their networks while simultaneously enabling the low-cost delivery of value-added services such as virtual private networks (VPNs), toll-quality voice, multi-tiered data and gaming services, and video. The VantEdge is a flexible platform--optimized for both aggregation and subscriber termination--offering service providers rapid payback, typically less than twelve months.

"Even in this difficult telecommunications climate, we continue to see an urgency to improve existing broadband access networks among ILECs, IXCs, and PTTs worldwide," said Rick Gilbert, president and chief executive officer of Copper Mountain Networks. "We are pleased to be the first to market with a critical new building block that allows these networks to scale profitably and enables a wide range of broadband services."

"We have found no other CO-based product that can match the VantEdge's combination of performance, flexibility, and networking capabilities," said Keith Higgins, vice president of marketing for Copper Mountain Networks. "Bringing significant innovation to the central office differentiates us from incumbent equipment manufacturers, and being commercially available coupled with our track record of building carrier-class solutions differentiates us from everyone else."

About the VantEdge(TM) Broadband Services Concentrator

Purpose-built for the CO, Copper Mountain's NEBS Level 3-compliant VantEdge Broadband Services Concentrator offers a high-performance platform with 130 Gbps of switching capacity and support for more than 80 subtending ports and up to 1,824 subscriber ports per chassis. The VantEdge offers a unique architecture with port- and queue-level simultaneous coordination of packets and cells, enabling highly cost-effective delivery of both IP and non-IP services and ensuring the largest possible addressable market for broadband service providers. Designed for seamless integration and interoperability with other vendors' DSLAMs, ATM switches, Layer-3 switches, and routers, the VantEdge cost-effectively addresses key scalability limitations of existing network architectures and enables their evolution to support new value-added services. With a broad set of IP, PPP, ATM, and Ethernet-based networking capabilities, the VantEdge simultaneously enables several types of subscriber aggregation and dramatically improves scalability. The VantEdge's auto-sensing and auto-provisioning capabilities enable providers to minimize the costs of adding subscribers, provisioning services and changing subscriber profiles. The VantEdge is commercially available in two form factors, including a 23" version and a 19" ETSI version.
