The NTT Group is engaged in building systems to ensure the prompt restoration of communications systems and the maintenance and securing of means of communications within and outside affected areas, even when a disaster has caused power outages or our network is inundated with calls or mail to the affected areas.
We also provide various systems and solutions to assist our customers in preparing for disasters.
Measures to improve communications network reliability
The NTT Group has learned many lessons during past disasters that it applies to implement various measures aimed at enhancing the reliability of its communications networks. To prevent the failure of communications services during a disaster, we not only implement transmission line multi-routing, but also design communications equipment, buildings, steel towers, and other facilities to withstand disasters in accordance with predetermined standards.

Securing critical communications
When a disaster strikes, the telephone system of the affected area is inundated with calls, causing network congestion. Under such conditions, we suppress ordinary phone traffic to secure critical communications services necessary to conduct emergency rescue and restoration operations and keep emergency number services such as 110, 119, and 118 going.
We also provide Disaster Emergency Message Dial (171) and other services as a means of checking on the safety of relatives and friends in affected areas, make our public telephones available free of charge, and provide specially installed public telephones at evacuation sites and other locations in affected areas for use by residents.

Prompt restoration of communications services
The NTT Group stations highly mobile disaster response equipment such as power supply vehicles, portable satellite equipment, and portable mobile base stations at locations throughout the country to aid in the prompt restoration of services and securing of critical communications in disaster stricken areas. In the event of a major disaster, a disaster management headquarters and other emergency structures are also immediately set up and work to promptly restore communications services.

A system to support prompt decision making in times of emergency
In March 2008, NTT DATA released its AGADIS emergency command support system, a computerized response manual for use in the event of a disaster or other emergency situations. This system supports quick decision making by emergency and disaster response managers by providing a database of criteria for decision making and response methods in given states of emergency.

Local disaster response information delivered via large-screen displays
In collaboration with FUJITSU FIP CORPORATION, NTT Communications Group company NTT Resonant provides an earthquake information delivery solution that displays earthquake early warning alerts and other useful information in the event of a disaster on large screens fitted to public facilities, office buildings, etc. Before the large tremors of an earthquake occur, an earthquake early warning alert is sent and information on anticipated seismic intensity and time until tremor is displayed to alert the public. After the earthquake strikes, video images depicting conditions in the area, maps, and evacuation routes are displayed to prevent commotion.

Supporting business continuity in times of disaster
In June 2008, NTT Communications Group company NTT Com Technology established the Sapporo BC Center, an operation center that monitors and operates corporate ICT systems and networks.
The center was established to address increasing awareness of the importance of business continuity planning (BCP) and a desire by businesses to distribute their operations so as to facilitate the continuation of business activities in the event of a disaster or other contingencies.
The center provides round-theclock, 365-day support for the operations management of customers' systems. It is housed in a quake-proofed building able to withstand earthquakes of level seven seismic intensity and equipped with in-house power generation to guard against power outages.
