  • Telecom Firm Owned by IIJ, Toyota, Sony to Offer High-Speed Services
  • February 1, 1999 (TOKYO) — Crosswave Communications Inc. (CWC) announced Jan. 26 the outline of its telecommunications services that are slated to begin in April.
    CWC is a Type-1 telecom carrier set up as a venture among Internet Initiative Japan Inc. (IIJ), Toyota Motor Corp. and Sony Corp.

    “By building an infrastructure specifically for data communications, rather than a telephone network, we’ll be able to provide high-capacity communications services at a low cost,” said Koichi Suzuki, president of IIJ and CWC.

    Established in October 1998, CWC is the first telecom carrier of its type in Japan. Its services are based on an indefeasible right of use (IRU) agreement, whereby CWC will lease optical-fiber cables from KDD Corp.

    Toyota, which was the largest shareholder in Teleway Corp., a new common carrier, also is the second largest shareholder in KDD following the KDD-Teleway merger.

    In April, when it launches its high-speed leased-line service, CWC will have 25 access points in the Tokyo, Osaka, Nagoya, and Hokuriku (western Honshu) service areas. Lines to subscriber homes will be provided by Nippon Telegraph and Telephone Corp. (NTT) and regional common carriers.

    The leased-line service will be available at speeds of 1.5Mbps, 45Mbps, 150Mbps and 600Mbps, the company said.

    The user-network interface is identical to the type of ultra high-speed leased-line services offered by existing carriers. Its 600Mbps service, however, will be targeted at Internet service providers and other companies, because the fiber to the home that is now available cannot handle such speeds.

    Pricing details are not yet known. However, Suzuki expects that charges will be set “at less than half the price of existing high-speed digital leased-line services.”

    CWC will introduce two additional services in September. The first is a network platform service, which will enable interconnection of subscriber locations without connecting them in a mesh topology. The principal feature is that charges will be based on bandwidth and the number of connection points and not transmission distance.

    The other additional service is a dial-up port service. CWC will provide access points for companies to use for remote access, and for Internet service providers to offer dial-up connection services. Details and costs of the additional services are yet to be decided.

    Also, CWC plans to offer a network monitoring service and a co-location service for customers to set up their own equipment inside CWC premises.

    Its long-term plans include providing a high-speed communication service using Internet Protocol (IP).

    CWC did not specify service charges, but it will likely announce very low fees. They will be sufficiently low-priced to upset the pricing rationale of existing Type-1 carriers. Low prices are possible because CWC is building a backbone network without any exchange equipment.

    The optical-fiber strands will be leased from KDD on the basis of a long-term agreement, and will be connected directly to wavelength-division multiplexing (WDM) equipment. Initially, backbone bandwidth will be up to 100Gbps. The WDM equipment will be connected to synchronous optical network (SONET) transmission devices, and CWC will link customers directly to the SONET equipment.

    The network consists only of the WDM and SONET devices. This simple network structure explains CWC’s rationale for preparing to implement very low communication charges.
