AT&T Secures New Contract with Placentia-Yorba Linda Unified School District

California School District Expands Network to Support VoIP

Placentia, California, May 19, 2006

AT&T Inc. (NYSE: T) today announced a new optical services contract with Placentia-Yorba Linda Unified School District (PYLUSD), a California school district with 34 schools located in Orange County.

Under the terms of the contract, AT&T will deploy its OPT-E-MAN® switched Ethernet service to all PYLUSD locations, allowing communications between the schools and the district office through pure Ethernet connectivity. The service will allow the district to move toward its vision to provide access to information resources and communication for all parents, students, and staff through a single integrated portal available anywhere, anytime.

In addition, the optical network will enable centralized control of the network from the district office for increased security of data transfer and student records. The district will also enjoy faster Internet connection speeds with increased reliability and will be able to seamlessly scale and integrate future communications services, such as VoIP, via the converged network infrastructure.

By connecting multiple facilities onto a single network, PYLUSD will now be able to meet the current bandwidth and data-transfer needs of its students and faculty with the flexibility to accommodate additional bandwidth-intensive applications in the future, if needed.

"We were in search of a provider that could deliver a cost-effective network capable of supporting advanced applications for a large school district," said Bob Blackney, director of Technology of Placentia-Yorba Linda USD. "The solution provided by AT&T will help us continue our commitment to giving our students a first-rate education now and in the future."
