PALO ALTO, Calif. -- Innovative Independent Operating Company Deploys VantEdge for Secure Aggregation of Subscriber Traffic

Copper Mountain Networks, Inc. (Nasdaq:CMTN), a leading provider of intelligent broadband access solutions, today announced that Hayneville Telephone Company, Inc., an innovative Independent Operating Company (IOC) in Alabama, has selected the VantEdge 3000 Access Broadband Remote Access Server (BRAS) for broadband aggregation.

The VantEdge was selected to provide a highly secure means of aggregating broadband subscriber traffic over the previously existing Ethernet bridged network. That network was susceptible to Denial of Service (DoS) attacks that simultaneously and significantly degraded the throughput and responsiveness of many of their broadband end users.

"We needed a cost-effective broadband aggregation solution that would help us isolate and eliminate denial of service attacks," said Lee Whitney, CEO at Hayneville Telephone and Camellia Communications. "We were impressed with how easy and quick the VantEdge was to install and manage, and noticed an immediate improvement in network performance and end user throughput. Our customer trouble tickets have decreased by 75%, both increasing customer satisfaction and freeing valuable operations personnel time."

"With increasing numbers of broadband subscribers and the proliferation of viruses, preventing and minimizing the effects of denial of service attacks are of high importance to our customers," said Mark Tiedeman, Vice President of Marketing at Copper Mountain Networks. "We are very pleased that Hayneville Telephone has selected the VantEdge Access BRAS to provide secure broadband aggregation."

Using the VantEdge's advanced IP intelligence, broadband service providers can provide better isolation between subscribers' traffic, prevent commonly found classes of DoS-prone traffic from entering the network, limit the amount of traffic per subscriber, and better control IP address usage. These capabilities minimize the occurrence and effects of network DoS attacks and, when coupled with the powerful, GUI-based CopperView Element Management System, facilitate identifying and isolating them when they occur.
