Howell Allen Clinic Selects AT&T for New Network Services

Nashville, Tennessee, November 14, 2007

AT&T Inc. (NYSE:T) today announced a new contract to provide managed services to Howell Allen Clinic, a six-location, neurosurgical care practice with headquarters in Nashville. Howell Allen Clinic serves patients in Nashville, middle Tennessee, southern Kentucky and northern Alabama.

Under the terms of the three-year contract, AT&T will deliver a robust Managed Internet Service (MIS) solution and will provide much-needed bandwidth across a converged, Internet Protocol (IP)-based network. The MIS solution is intended to support advanced data communications, file transfers and other important business corporate operations for Howell Allen Clinic.

The flexibility of MIS allows the service to expand when additional bandwidth is needed to accommodate large files (e.g., imaging and electronic medical records) across multiple clinics, an imaging center and an outpatient surgery center as well as area hospitals. In addition, this flexible network solution provides redundancy and increased reliability for greater network efficiency and availability.

"The reliability provided by the AT&T solution was essential for us as a health care provider," said Jeff Runion, chief information officer with Howell Allen Clinic. "Our patients and our service partners depend on on-time information and data. AT&T's advanced data support system will give us the best communications tools to provide exemplary care to our patients."

In addition to the MIS solution, AT&T will also add two metro Ethernet connections to the existing two connections and convert Howell Allen Clinic to a full metro Ethernet network. The result will not only increase image-transfer speed but will also enhance internal and external communications with a state-of-the-art IP phone system.
