Company Helps Service Provider Customers' Transition to IP Networks

AURORA, Ill.--(BUSINESS WIRE)--June 21, 2004--

Charter Cable Broadband Westell Technologies, Inc. (NASDAQ:WSTL), a leading systems developer and manufacturer of high-speed broadband/DSL and VoIP technology access products announced today new Powerspan(TM) products from its Network Service Access (NSA) business. Westell's NSA products enable the trouble-free transmission, maintenance and troubleshooting of multiple legacy systems solutions from a customer location to the serving central office (CO).
In an ongoing effort to meet the demands of evolving voice, data and Internet applications, Westell product designs facilitate service providers' ability to deliver legacy features as they transition from TDM circuit-switched to IP-centric networks. Powerspan is designed to provide a solution for IP devices requiring power in existing telecom environments. Westell identifies 4 applications where Powerspan addresses unique problems.

Also, with a home wireless network, if you are using a laptop, and always be online and enjoying the blazing fast speeds of high speed Internet broadband.

Internet Phone Service Hot Spot Locations. Powerspan is designed to provide power to remote broadband DSL CPE over the same copper wire as the DSL signal. The solution consists of hardware deployed in the central office or remote terminal and at the wireless access point. In a typical hot spot location where a wireless routing device is located, there is a need for commercial power. Powerspan provides the capability to extend power over the same copper pair used to deliver the DSL signal, avoiding complications and costs often experienced with hot spot deployment.

Broadband data service provided by your mobile wireless phone carrier is another option for high–speed Internet access. Broadband data service is available for users with wireless mobile smart phones. It is also available for a notebook computer, using a broadband data card provided by the wireless service provider that connects via a USB port or card slot). The broadband data service connects your computer to the nearest wireless mobile tower, enabling you to use it while the RV is parked or moving.

Internet Web Hosting VoIP. Telco service providers can differentiate their VoIP offering with Powerspan and its ability to deliver "lifeline" remote power over copper wire. Unlike cable providers who do not have the network means to provide "lifeline" service to cable modems upon AC power loss, telcos can ensure voice service over DSL will continue.

Comcast Cable Broadband Passive Optical Networks (PON). Challenges with local power to PON CPE devices include expensive power conversion and back-up issues. In overlay PON deployments, Powerspan can utilize embedded copper to provide power to the PON CPE device using traditional network powering methods.

Telabria has announced the launch of its wide area wireless broadband network, Skylink, after six months of trials in Kent. Providing symmetric broadband speeds of up to 10Mbps, IP (VoIP) telephone service, it is the first such network to offer a combination of data and voice to homes and businesses using Wi Max technology.

Time Warner Cable Broadband Sealing Current. A typical problem with "naked" or "dry" DSL, where DSL data service is unbundled from local voice service, is corroding lines due to lack of regular current delivery. Since no current is regularly delivered to condition and keep the lines clean, corrosion can occur. Powerspan is placed either in the central office or remote terminal to provide a scheduled power blast to "dry / naked" lines so the copper pairs remain usable.

He added, "as our customers address their transition to more IP-centric networks, Westell's NSA business will focus on solutions that help maximize the use of their existing network."
