AT&T* today announced that it has received recognition for its leadership Business Ethernet from leading analyst firm, Vertical Systems Group.  On Vertical’s year-end 2010 U.S. Business Ethernet Leaderboard,¹ AT&T has been ranked the top provider of Ethernet ports – for the sixth year in a row.

According to final 2010 share results published in Vertical Systems Group’s web-based ENS (Emerging Networks Service) research service, AT&T retained the number one position in the U.S. Business Ethernet market.  Vertical’s data show that AT&T has steadily increased its port share in each of the past three years, and has widened its lead over all other providers selling retail Business Ethernet services in the U.S. market.

Vertical Systems Group also reports that the total number of U.S. Business Ethernet connections increased 34% during 2010.  Enterprises have expressed greater confidence than ever in the reliability of Ethernet in supporting “ultra-high bandwidth applications” that drive their business processes.  AT&T believes that its proven track record in providing quality services has contributed to the fact that companies continue to choose AT&T over its competitors for Ethernet.

AT&T delivers Ethernet solutions to meet customers’ business needs, supporting applications such as cloud computing, data center consolidation, mobile access, content distribution and real-time video, along with capacity for bandwidth growth for Virtual Private Networks (VPNs) and Internet access.  AT&T’s Ethernet services, available in 45 countries around the world, offer a wide range of features and speeds, complemented by carrier-grade resiliency, operational simplicity and industry-leading Service Level Agreements (SLAs).
