We are improving our communications network technologies to minimize the impacts of disasters around the world.

Advanced Network Technologies and Monitoring Systems

• Multi-Routes, Redundancy, and 24/7 Monitoring Ensure Reliability

  NTT Communications operates Japan’s communications backbone network. We ensure network reliability even in disasters or other emergencies by securing multiple routes, redundant and decentralized equipment and facilities, and 24/7 network monitoring.

  In February 2007, we signed an agreement with TransTeleCom to construct an undersea fiber-optic cable system between Japan and Russia by the end of 2007. The system will connect with TransTeleCom’s 50,000-kilometer transcontinental optical route along the Trans-Siberian Railway to become the shortest uninterrupted link from Japan to Russia and elsewhere in Europe.

  By this new route in addition to an existing Indian Ocean link between Japan and Europe, we will continue to meet the requirements of multinationals using data communications services and will also strengthen our network resiliency.

• CCNC Maintains Quality, Efficiency, and Reliability

  The NTT Communications Customer Network Service Center (CCNC) oversees our network services to maintain reliability and support diverse operational modes. We can thus deliver unsurpassed quality, efficiency, and reliability today and well into the future.

  ■CCNC System

  1. One-stop customer service to resolve product failures

     A single, centralized contact point lets us quickly address customer concerns.

  2. Monitoring and controlling equipment at network service nodes

     Our 24/7 nationwide monitoring keeps our network services reliable.

  3. Customized service level agreements and failure analysis reports

     We manage quality in line with service level agreements and failure analysis reports.

Serving Worldwide Needs

• Global Network Services

  NTT Communications provides seamless global services, including such highly reliable offerings as a global IP-VPN and a Global Tier 1* IP backbone. We are reinforcing our services worldwide, particularly in fast-growing Asian-Pacific markets, notably China and India, where we opened affiliate offices.

  We opened our Dubai Representative Office in December 2006 to enhance our Middle Eastern operations. We launched the Warsaw Representative Office in April 2007 to serve the network and systems needs of multinationals expanding in central and eastern Europe.

  * A Global Tier 1 is an Internet service provider that owns a high-bandwidth worldwide IP backbone and can control quality without relying on upstream providers.

  

  Our Global Network of Subsidiaries and Affiliates (covering 50 cites in 21 countries, as of July 31, 2007)

• The Technology for Laying Submarine Cable is Also Used for Installing Seismographs

  

  The Subaru lays undersea communications cable

  NTT World Engineering Marine Corporation (NTTWEM) lays and maintains the domestic submarine communication cables around Japan as well as the cables across the Pacific Ocean, throughout South Asian and the Indian Ocean coastal areas. NTTWEM and NTT Submarine Cable Engineering Center, (which was the former organization of NTTWEM) have installed most of the seismographs located at more than 1,000m water depth. NTT Communi-cations group developed this technology and it is used to study earthquakes and also used in emergency notices around Japan as and when required.

Disaster Mitigation

• Keeping Networks Reliable after Disasters

  

  As mentioned on page 13, our basic disaster policy is to make our networks more reliable, secure vital communications, and swiftly restore services. We are building networks to alleviate the potential impacts of earthquakes, storms, and tsunamis.

  We formulated a disaster mitigation plan as a designated public corporation in keeping with the Disaster Countermeasures Basic Act and the Civil Protection Law*. We conduct regular drills based on various scenarios to reinforce disaster preparedness.

  We held four disaster drills for more than 1,000 participants in fiscal 2006. We will continue to enhance disaster responsiveness in collaboration with national and government agencies and all other NTT Group companies.

  * The official name of the Civil Protection Law is the Law concerning the Measures for Protection of the Civilian Population in Armed Attack Situations.

• System to Help Rebuild Networks after Major Disasters

  We created the Disaster Recovery System to overcome network disruptions following major disasters. This independent system would draw on usable resources to quickly identify and assess troublespots, design bypass routes, and set up equipment. We plan to commercialize a desktop version of this system in fiscal 2007.

• Testing Earthquake Early Warning for Consumers

  In December 2006, we joined hands with HALEX Corporation, Val Laboratory Corporation, and the Japan Meteorological Agency in a project to test an earthquake alert model for consumers. As soon as we receive quake newsflashes on primary waves from the agency, we send IPv6 multicasts to participating consumers before the more destructive secondary waves arrive. We will use findings from a survey of these consumers to eventually distribute quake newsflashes to the general public.

  We began testing Earthquake Early Warning for consumers in November 2006. We hope that businesses can harness such information to minimize the impact of quakes on trains, elevators, and other facilities and instruct employees to seek shelter.

• Mobile Service to Confirm Safety and Broadcast Notices

  We launched a new service that helps companies to address increasingly complex natural and man-made risks by placing calling employees by cellphone, wireline phone, or through the Web. Companies can also simultaneously notify all employees and have administrators assess the results. Our service helps businesses to quickly evaluate and recover from disruptions after disasters so they can assist communities.

• Kankyou-goo Website Highlights Disaster Prevention Month

  

  Disaster readiness feature on Kankyou-goo website

  Disaster Prevention Month every September features numerous events. In fiscal 2006, The Kankyou-goo environmental portal of NTT Resonant Inc. presented a special feature on the importance of daily readiness for disasters. The feature emphasized the themes of knowledge, experience and involvement, and preparations.
