  • Japan's First xDSL-Based Internet Service to Start in March
  • November 3, 1998 (TOKYO) -- Shikoku Information and Telecommunication Network Co., Inc. (STNet) said it will use xDSL ("x" digital subscriber line) technology in its Internet access services as early as March 1999.
    This will be the first deployment of xDSL technology in Japan.

    STNet, a regional Type-1 telecommunications carrier (new common carrier), will start providing xDSL-based Internet services to enable high-speed data transmission using copper-wire subscriber lines (the existing cable infrastructure).

    The xDSL technology to be offered by STNet is symmetric DSL (SDSL). SDSL uses a single pair of copper telephone wires to provide data transmission at speeds of up to 1.5Mbps.

    STNet's Internet access service called STCN now uses optical fiber for supplying leased-line services at speeds of 192kbps and higher. But by using copper cables and SDSL modems, the company aims to provide customers with the same services, but at lower rates.

    With the upcoming initial deployment of xDSL services in Japan, the Ministry of Posts and Telecommunications (MPT) must set technical standards to enable carriers to build the infrastructure for such services.

    "STNet and other carriers in Japan want to provide xDSL services, and the United States Trade Representative (USTR) has inquired about deploying xDSL services here. The MPT will therefore develop technical standards for xDSL," said an official in the Telecommunication Systems Division of MPT's Telecommunications Business Department.

    The ministry will submit proposals for implementing technical guidelines to the Telecommunications Council, which is due to meet in December, and it plans to revise ministerial ordinances in January 1999.
