AT&T Announces New Contract with 360 Architecture Inc.

Missouri-Based Architectural Practice Upgrades Network Using AT&T Services

Kansas City, Missouri, June 11, 2007

AT&T Inc. (NYSE:T) has announced a new networking services contract with 360 Architecture Inc., an architectural practice with headquarters in Kansas City, Mo. Under the terms of the three-year contract, AT&T will serve as the primary data services provider and will deliver Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) and AT&T Integration services.

With AT&T VPN, 360 Architecture will have complete management control of its network options and will use the service's benefits, including MPLS-based security, any-to-any connectivity, traffic prioritization, Web-based reporting and flexible billing options. Additionally, with AT&T Integration services, 360 Architecture will be able to rely on AT&T to provide industry-leading installation and customer support.

"As an architecture firm, some of the files we share are high-resolution images that require large amounts of bandwidth and can bog down our network," said Jeff Hamer, director of Information Technology, 360 Architecture. "The solution provided by AT&T will allow us to transmit large data files faster and more securely, creating a seamless communication network that will help us increase efficiency within our company."

With this solution, 360 Architecture will experience improved connectivity in voice and data communications for its four locations: Kansas City, Mo., Columbus, Ohio, Des Moines, Iowa, and San Francisco. Along with the support of a newly installed Local Access Network (LAN) infrastructure at 360 Architecture headquarters, the VPN will also allow for faster desktop communications by increasing data transfer speeds from 100MB to 1GB. This will allow 360 Architecture employees to send the larger, bandwidth-intensive data files that are associated with their architecture business at much faster speeds, thus enabling users to view files more quickly and work more efficiently. Additionally, with the solution's remote access feature, employees who are on-site or traveling will have the same level of connectivity to critical business applications and data.
