CLEC and US WEST Tests Ordered by Minnesota PUC are Successful

GOLDEN VALLEY, Minn. (Nov. 2, 1999) - The nation's first test over a shared telephone line between US WEST and Covad Communications (Nasdaq: COVD) was successfully completed today in Minnesota, announced Covad. The line-sharing test was ordered by the Public Utilities Commission (PUC) of Minnesota on September 22, 1999 to determine if Covad, the leading national digital subscriber line (DSL) broadband services provider, could successfully deliver digital data service over the phone company's voice line, while maintaining high quality for both data and voice.

Line-sharing is the typical method the telephone companies use to deliver DSL data to end-users, utilizing the same telephone line that consumers use for voice communications. Currently, the phone companies don't share lines, so companies like Covad are forced to lease a separate line from the telephone companies to deliver data. As a result, the end-user is required to pay for a second line if they want a choice of providers for high-speed DSL broadband Internet access to their home or business.

"We are pleased and very excited about the early line-sharing test results as it's a huge step in the right direction for both Covad and for consumers across the country who want high-speed, 'always-on' broadband Internet access," said Dhruv Khanna, Covad's general counsel and executive vice president. "If all goes as planned, citizens of Minnesota will be the first to experience the benefits of line-sharing. Line-sharing will reduce end-user costs, decrease installation time, and allow consumers to choose the best service provider for data and voice services."

The successful result of the precedent-setting tests proves that line-sharing is feasible. Ultimately, line-sharing is expected to lower the cost of Covad's high-speed residential DSL service and give consumers a greater choice of broadband service providers by eliminating the need for a second line for data service.

Covad completed its lab tests for the Minnesota trials on October 19. The field tests ordered by the Minnesota PUC, which began today in Minnesota, are expected to run for two weeks. Final test results must be submitted to the Minnesota PUC no later than November 22.
