SANTA CLARA, Calif.--(BUSINESS WIRE)--March 17, 2000

CopperCom, a Silicon Valley company that is Giving Voice to DSL(TM), was one of ten companies chosen as `Most Likely to Succeed' at the Network Outlook 2000 conference hosted by Technologic Partners this week. CopperCom was selected for

the "Investors' Choice" honor from among 90 privately financed technology companies that presented their business plans to an audience of several hundred venture capitalists, money managers, investment bankers, and industry executives.

"CopperCom set the investment community on its ear by announcing a merger with DTI Networks at the Network Outlook conference," said Timothy P. Savageaux, a research analyst at W.R. Hambrecht + Co. and one of the judges for the "Investors' Choice" awards. "The merger was very unexpected from two pre-IPO start-ups that are in very hot markets -- VoDSL and softswitching -- and defines a compelling migration path towards the next generation carrier central office. With a $15 billion annual market opportunity at stake, the merger of CopperCom and DTI Networks raises the bar for competitors in this space."

Selection of the ten "Investors' Choice" companies honored at the Network Outlook 2000 conference was based on voting by the audience, as well as on the recommendation of a distinguished panel of technology investors that included Neal Dempsey, a general partner at Bay Partners, David W. Hanna, chairman of Hanna Capital Management, Bruce Sachs, general partner at Charles River Ventures, and Timothy P. Savageaux, a research analyst at W.R. Hambrecht + Co.

"We are very honored to be selected as `most likely to succeed' two years in a row by the distinguished Network Outlook audience, a group of people who understand what it takes for a start-up to be a winner," said Cynthia Ringo, CopperCom CEO. "This award is a huge vote of confidence for CopperCom's merger with DTI Networks and the combined solutions we are providing to our customers."

With its merger with DTI Networks, CopperCom is leading the Voice over DSL market into the next phase of evolution beyond pure transport by expanding its service provider offerings to include local exchange switching, standard voice calling features, and revolutionary personalized calling features. VoDSL solutions that support the delivery of multiple phone lines plus high-speed Internet access over a single copper pair are already bringing important benefits to service providers, but the dramatic expansion of the scope of VoDSL being brought about by CopperCom will deliver even more compelling benefits -- such as lowering the cost of local exchange switching, enabling the delivery of highly differentiated voice services, and easing the migration to end-to-end packet voice networking.
