UniFirst Selects AT&T for Network Expansion and Upgrade

Wilmington, Massachusetts, July 6, 2007

AT&T Inc. (NYSE: T) has announced the growth of a decade-long relationship with UniFirst Corp. (NYSE: UNF), one of North America’s largest workwear and textile services companies. AT&T will enhance UniFirst’s companywide network platform and bolster the network’s overall reliability.

AT&T will enhance the UniFirst network by converting existing Managed Internet Service (MIS) circuits within 140 office locations to AT&T’s Virtual Private Network (VPN) platform. AT&T’s VPN, made possible by AT&T’s Multiprotocol Label Switching (MPLS)-based network, will create a secure wide area network (WAN) environment for UniFirst. AT&T will also add 25 new sites to the VPN platform, providing UniFirst with seamless connectivity to a total of 165 locations in the United States and Canada.

UniFirst will also implement AT&T’s ACCU-Ring® Network Access Service, a private Synchronous Optical Network (SONET) ring that consolidates network traffic, at the company’s headquarters in Wilmington, Mass. ACCU-Ring Service provides a two-way digital channel for voice and data transmission and creates a reliable environment for communication within the defined circumferential network.

“We look forward to managing this network deployment with AT&T,” said Tom Lally, director of information technology for UniFirst Corp. “Having 165 locations supported by the same network will encourage greater collaboration and allow us to operate more efficiently.”
