Southgate, Michigan, September 21, 2006 - AT&T Inc. (NYSE: T) today announced a new optical and data networking services contract with The Library Network (TLN), a public library cooperative serving southeastern Michigan. Under the terms of the three-year contract, AT&T will deliver AT&T OPT-E-MAN® and AT&T network-based virtual private network (VPN) to 55 libraries throughout the state.

Together, these products and services will deliver the latest-generation technology to the libraries allowing them to access headquarter servers to support bandwidth intensive applications.
