TW Telecom (styled tw telecom), was a business telecommunications company headquartered in Lone Tree, Colorado, United States. The company provided business voice services, transport, Internet, data services and wholesale fiber capacity. It was an early leader in the deployment of Ethernet for metropolitan areas, dubbed Metro Ethernet. The company was acquired by Level 3 Communications on November 1, 2014. ==History== Founded in 1993 as Time Warner Communications, the company was a joint venture between US West and Time Warner Cable a division of Time Warner Entertainment, to deliver telephone services over a hybrid fiber and coaxial network. The company was successful in their efforts, but at the time the cost to build fiber directly to consumer's homes proved too expensive to be profitable. In the mid-1990s the company evolved into a "carriers carrier" selling "dark fiber" capacity to other telecom and Internet providers to supplement their networks. The company played a role in growth of the Internet as it built and assembled a national fiber network. Management realized that to continue to grow it needed to offer communication solutions alongside its wholesale network offerings. In July 1998, Time Warner Communications became a separate entity and was reorganized into Time Warner Telecom LLC. In May 1999, the company made an initial public offering. In 1997, the company began delivering communications services to medium and large business customers, carriers and governmental entities. In March 2003, the company introduced Metro Ethernet services, an expansion of the Ethernet model of building-wide communications networks. The metro capability basically expanded the use of Ethernet across a city or region allowing for seamless connectivity of locations that were on the same network ring. This capability enabled the company to offer advanced Internet, data and voice services. In July 2006, Time Warner Telecom acquired Xspedius Communications for $531.5 million, adding additional metropolitan markets. TW Telecom had operations in 75 markets across the U.S.. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TW Telecom」の詳細全文を読む スポンサード リンク
