New Networking Contract Expands Support for Comcast Digital Voice Service

FOR RELEASE: WEDNESDAY, JULY 27, 2005

BEDMINSTER, N.J.– AT&T today announced a new contract with Comcast, the nation’s leading provider of cable, entertainment and communications products and services. The new contract extends AT&T’s existing network support to Comcast’s new voice service, known as Comcast Digital Voice, which enables voice communications using Internet Protocol (IP).

The new agreement establishes AT&T Global Wholesale Services as a key supplier of the nationwide transport and termination services that will enable Comcast Digital Voice customers to enjoy higher quality telephony services.
“We are pleased to continue our relationship with AT&T,” said Catherine Avgiris, senior vice president, finance and administration of Comcast Voice Services. “AT&T’s networking expertise, coupled with their nationwide coverage, provides us with additional means to deliver valuable services like our differentiated IP-based phone offering – Comcast Digital Voice – to our customers.”

“It’s always rewarding to do business with an important customer like Comcast,” said Kathie Morrissey, president, AT&T Global Wholesale Services. “For years, AT&T has been applying its unique networking expertise to enable cable companies to evolve their businesses. Our flexible approach to networking provides Comcast the choices they require to deliver their services — whether connectivity, voice services, content delivery, hosting, call center solutions or applications.”

AT&T serves the wholesale market with a comprehensive portfolio to help businesses extend their reach, strengthen their network infrastructure, add operational efficiency and complement their existing offer sets with new value-add application services, as well as solutions that are unique to the wholesale segment.

In October 2004, the Yankee Group ranked AT&T “No. 1 Wholesale Services Provider” and, in 2005, Boston-based consultancy Atlantic-ACM recognized AT&T Global Wholesale Services with “2005 U.S. Wholesale Carrier Excellence Awards” — for Voice Services, Data Services, Customer Service and Sales Representatives.
