FOR IMMEDIATE RELEASE

Bellingham, Wash., March 4, 2002 - Power system manufacturer Alpha Technologies is now offering a new Dual Utility Swtich for their Novus XT systems. The new DUS XT is designed to provide operators with the ability to switch between two Novus XT power systems providing an added level of wireless network redundancy and reliability.

Alpha engineers developed the Dual Utility Switch (DUS) product to allow operators the option of connecting two Novus XT power systems together at a single installation site. Operators can installl a DUS XT where two Novus XT systems are used to provide backup power for the main call processor and for multiple sector radios. In the unlikely event of a localized power outage occuring in conjunction with a Novus XT failure, the DUS XT will automatically switch to and draw critical power from the second Novus XT power system. This keeps the main call process functioning at all times and significantly increases overall network reliability.

Alpha Technologies Inc. develops power conversion, protection and standby products for telecommunications and cable television industries, including custom, application-specific power solutions. In addition to product development, Alpha Technologies provides a comprehensive range of installation and maintenance services to support its global customer base. Alpha Technologies is a member of The Alpha Group of companies.

The Alpha Group represents a global alliance of independent companies that share a common philosophy - create world-class powering solutions for communication, commercial, industrial and renewable energy markets.
