Covad Completes Build-out of Nation’s Largest Next-Generation Telecommunications Network Ahead of Schedule

Increased bandwidth capability enables advanced voice, video, and business-class broadband applications

San Jose, Calif. (December 27, 2006) – Covad Communications Group, Inc. (AMEX: DVW), a leading national provider of integrated voice and data communications, today announced that it has completed the build-out of its nextgeneration telecommunications network. Covad now operates the nation’s largest ADSL2+ network, capable of providing high-speed data and next-generation voice services to millions of businesses and residences.
Covad’s next-generation network covers 14 million homes and businesses in Atlanta, Chicago, Dallas, Los Angeles, New York, Miami, Philadelphia, San Diego, San Francisco, San Jose, Seattle, and Washington, DC. In these markets, Covad is capable of providing customers broadband connections with data speeds of up to 25 megabits per second. This bandwidth capability currently enables Covad to offer line powered voice access, a cost-effective alternative to traditional residential phone service. Covad has also announced plans to introduce higher-speed broadband access and new business-class services such as bonded T1. Covad expects to make these higher-bandwidth services available directly to Covad’s business customers and indirectly via Covad’s Alliance Channel and wholesale partners in 2007.
“Our next-generation network build-out has been completed ahead of schedule. This new network positions Covad at the forefront of telecom providers, allowing us to offer the solutions that businesses demand, and to continue our tradition of
innovation.” said Eric Weiss, Covad chief marketing officer.
In addition to enabling next-generation products and services, the expanded network capabilities allow Covad to power bandwidth-intensive applications and provide an improved customer experience. “Covad’s deployment of its next-generation ADSL2+ network offers increased reach for the delivery of high speed services, and ADSL2+’s performance monitoring capabilities should enhance reliability and service levels,” said Cindy Whelan, senior analyst with competitive analysis firm Current Analysis.
“These capabilities are critical to customers who are increasingly using their broadband connections for voice and video applications.”
