LITTLETON, Colo., Feb. 6 /PRNewswire-FirstCall/ -- Time Warner Telecom Inc., , a leading provider of managed voice and data networking solutions for businesses, today announced that Vertical Systems Group has ranked it among the nation's top three providers of metro and national Ethernet connectivity for businesses. Vertical Systems Group provides in-depth, accurate, defensible statistics and analysis on networking markets with a focus on Ethernet services, IP VPNs, Frame Relay, Private Lines, ATM, DSL, MPLS, VPLS, and Internet Access.

"We are very pleased with this ranking, as it proves we continue to take market share from the incumbents with our broad and flexible product portfolio," said Mike Rouleau, Senior Vice President, Strategy and Business Development for Time Warner Telecom. "In 2003, as one of the first providers to offer a robust suite of Ethernet-based services in metropolitan areas, we recognized the versatility of the technology to deliver what customers needed for advanced communications capabilities. Since then, we have continued to add services that capitalize on these capabilities and offer users the ability to seamlessly converge their voice, data and Internet networks."

"Time Warner Telecom continues to demonstrate its leadership in delivering metro Ethernet by maintaining its market share versus other competitors," said Erin Dunne, Director of Research Services for Vertical Systems Group.
