                                                     with Juniper Networks

                                                      A new Japanese service provider is radically cutting the cost of telephony by sending consumer and
                                                      business calls over its all-Internet Protocol (IP) network and the Internet. Fusion Communications
                                                      Corp. sells Japan's first single rate, 24-hour-per-day, location independent voice service based on IP.
                                                      Speech quality rivals the expensive service from incumbent carriers. Fusion has slashed average
                                                      incumbent rates for three-minute calls by approximately 60% for local, 33% for national and 50
                                                      to 70% for international calls.
                                                      Popularity is soaring for this new service. Since its debut in April 2001, Fusion attracted a half million

                                                      performance and technical requirements for Voice over IP (VoIP) and other services led Fusion to

                                                      Fusion uses Juniper Networks IP routing technology to challenge
        Juniper Networks M-series                     Japan's incumbent telephony providers.
                                                      Until last year, Japanese telephony charges always became more expensive as calling distance
        routers to ensure stability                   grew. Fusion Communications devised a strategy to avoid the incumbents' overhead of building
                                                      and maintaining costly separate infrastructures for voice, data, Internet access, and other services.
        and achieve a lower cost                      To implement this strategy, Fusion built a single IP network as a foundation for multiple services,
                                                      thereby reducing costs of capital expenditures, network management, and operations. In turn,

        Yoshiaki Hirayama                             Fusion found that overlaying new IP services on a conventional circuit-switched network was
        General Manager                               inadequate for quality voice service. "We required a new technology, a new operating method and a
        Network Engineering Division                  new partner," says Yoshiaki Hirayama, general manager of Fusion's Network Engineering Division.

                                                     "Our construction policy was to focus the network on simplicity," says Hirayama. "We used a
                                                      redundant configuration of Juniper Networks M-series routers to ensure stability and achieve

                                                      Juniper Networks software provides reliable transmission of multiple IP services
                                                      Fusion chose IP routers from Juniper Networks for scalable performance, reliability, cost performance,
                                                      and strong support for an array of IP services. A key attraction was software support for Multiprotocol
                                                      Label Switching (MPLS), used to control simultaneous traffic flow of multiple services such as VoIP
                                                      and virtual private networks (VPNs)."No other routing systems came close to matching the capabilities
                                                      offered by Juniper Networks," says Hirayama.
                                                      Fusion bought and deployed a redundant mesh configuration of Juniper Networks M20 and M10
                                                      Internet routers. A pair of routers was configured for IP edge and access services in each of Fusion's
                                                      18 access points in Japan.
                                                      Since installation, Juniper Networks routers have enabled high speech quality in Fusion's VoIP services.
                                                     "We haven't seen any delay at the IP level and feel certain that the speech quality of our VoIP services
                                                      is almost as high as circuit-based offerings from NTT," says Hirayama.
