AT&T Provides Wireless Backbone to Cisco 3G WWAN HWIC Solution

Company’s 3G-Powered Wireless WAN Connectivity Service Is Key Component of Breakthrough Converged Wireline-Wireless Cisco Router Offering

ATLANTA, March 27, 2007 - AT&T (NYSE: T) announced today that the AT&T Wireless WAN Connectivity Service will be available in conjunction with the new Cisco® 3G-Enabled Wireless WAN High-Speed WAN Interface Card (HWIC) for the Cisco Integrated Services Router (ISR). AT&T made the announcement today at CTIA Wireless 2007® in Orlando, Fla., in conjunction with Cisco’s launch of its 3G Wireless WAN HWIC solution.

The Cisco 3G Wireless WAN HWIC is a wireless module that is enabled for AT&T’s UMTS/HSDPA-based BroadbandConnect service and is integrated in the Cisco ISR, which provides Internet Protocol (IP)-based data, voice, video and mobility services.

When using AT&T’s Wireless WAN Connectivity Service in conjunction with the Cisco 3G Wireless WAN HWIC solution, customers will have a truly diverse and highly secure wireless broadband backup to their Cisco ISR wireline data connections should those be disabled by cable cuts, weather or local access outages. Customers can configure their local area networks so that the Wireless WAN Connectivity Service automatically activates should the wireline connection be interrupted, thus achieving the truly redundant network architecture that helps ensure that critical applications keep running.

“The Cisco 3G Wireless WAN HWIC solution is the mechanism through which the worlds of wireline and wireless data are coming together for the first time within a single, enterprise-grade hardware platform,” said Jeff Bradley, vice president, wireless business data services, for AT&T. “This groundbreaking capability coupled with the AT&T Wireless WAN Connectivity Service - which was the first commercially available service of its kind - provides our joint AT&T and Cisco customers with a cost-effective, rapidly deployable, reliable and secure solution for remote sites and branch offices. This is an important addition to our portfolio of AT&T enterprise VPN resiliency options.”

With more than 2 million units shipped, the Cisco ISR has a significant installed base in enterprise branch offices, and medium-sized and small businesses. The Cisco ISR with an AT&T-powered Cisco 3G Wireless WAN HWIC provides customers with such advantages as:

* Automatic failover service for business continuity.

* Supplemental bandwidth access when the primary wireline link is overused.

* Rapidly deployable connectivity for temporary sites and businesses requiring portability or for remote locations lacking wireline infrastructure.

“AT&T’s Wireless WAN Connectivity Service is a tried-and true-solution that is a perfect complement to the Cisco 3G Wireless WAN High-Speed WAN Interface Card,” said Ian Pennell, senior vice president, access routing technology group, for Cisco. “While corporate mobile users will continue to adopt applications in a ’connected workforce,” the combination of AT&T and Cisco means it will increase the utilization of 3G applications and extend new business services to enterprises of any size"

AT&T expects to begin offering its wireless business customers the Cisco 3G Wireless WAN HWIC solution in conjunction with the AT&T Wireless WAN Connectivity Service in June 2007 through a co-sale arrangement with Cisco.
