AT&T Government Solutions to Manage Department of Defense Video Teleconferencing System

Vienna, Virginia, June 27, 2007

AT&T Inc. (NYSE: T) has announced that AT&T Government Solutions has been awarded a six-month $11.5 million contract extension from the U.S. Defense Information Systems Agency (DISA) to manage a global videoconferencing system for the Department of Defense.

U.S. military commanders throughout the world communicate on the DISN Video Services-Global (DVS-G), the Department of Defense's all-service video teleconferencing (VTC) system. The AT&T-managed global videoconferencing solution helps military commanders ensure quality decision-making between deployed forces and their U.S.-based support services. DVS-G supports more than 5,000 garrisoned and deployed units globally.

"Battlefield forces need secure, reliable and scalable global communications capabilities," said Don Herring, senior vice president, AT&T Government Solutions. "AT&T is proud to support DISA and U.S. military commanders around the world with our managed global videoconferencing solution. We'll use our world-renowned networking expertise to ensure that deployed commanders and their troops can share information reliably and in a secure manner."

Under the terms of the contract, AT&T will provide network management services for the DVS-G. AT&T will also provide such networking services as configuration and installation and inventory management services for DVS-G equipment.

The DVS-G operates six video hubs worldwide — four in the U.S., one in Germany and one in Kuwait. The DVS-G also supports conferences at the Department of Defense Unclassified, Secret and Top Secret classifications, as well as Allied and NATO Secret. AT&T developed, and has managed, the DVS-G for more than 10 years.
