Providing Stable and Reliable Communication Networks Supporting
Today's ICT-Driven Society with a Stable and Reliable Global
Network
At the NTT Communications Group, our vision is to be a global
IP solutions company. Backed by a global network and data centers
in countries throughout the world, we provide the IT services
that are indispensable to businesses and individuals in today's
IT-driven world. By consistently providing stable and reliable
services, we contribute value to customers in a world powered
by ICT. For the NTT Communications Group, this is the first
step in CSR.

Ensuring Network Reliability in the Face of
Disaster
|
|
The NTT Communications Group carefully prepares
for the possibility of large-scale, unforeseen disasters. Our
core policy is to constantly improve the reliability of our networks,
safeguard vital communications, and restore service quickly when
accidents occur. To this end we have adopted a range of effective
measures to maintain solid network reliability in the face of
earthquakes, flooding, or other disasters, including the following:
| (1) |
Looping of communication networks
and creating multiple routes through diversity of lines |
| (2) |
Building networks to withstand
earthquakes up to category 7 on the Japanese scale of intensity
(heavy structural damage) |
| (3) |
Tight security controls on
entry to and exit from communication facilities |
| (4) |
Backup power facilities to
prepare for power failures, such as failure-free equipment
and power generators |
To safeguard vital communications in the event of disaster, we
work closely with the entire NTT Group to ensure rapid equipment
recovery. Measures include:
| (1) |
Securing emergency communication
links with police, firefighters, local government, and other
important services to enable disaster relief and recovery |
| (2) |
Group-wide organizational measures,
such as a Disaster Response Headquarters that can react
rapidly in the event of disasters or accidents |
| (3) |
Provision of a Disaster Emergency
Dengon (Message) Dial (171) for emergency contact and for
confirming people's safety |
| (4) |
Equipment measures such as
the dispatch of mobile power generators, installation of
disaster-response equipment, and the use of helicopters
for locating accident sites and transportation of people/materials |
|
Japan is located in a region prone to frequent natural
disasters such as earthquakes and typhoons. In 2004, the
nation was struck by the Niigata Chuetsu Earthquake and
two major typhoons: Typhoon Meari, which struck Okinawa,
and Typhoon Tokage in Hyogo Prefecture. Since we prepared
multi-route network configurations and other measures,
NTT Communications' operations were unaffected by these
disasters, although some cables were damaged.
Thanks to close cooperation within the NTT Group and concerted
recovery efforts, the damaged equipment was quickly restored
to working order.

Network Technologies and Protective Systems for the Information Age
|
|
Reliable communication networks are the foundation of today's
ICT-based society. As a leading provider of communication backbones,
NTT Communications is securing that reliability by establishing
multiple routes throughout Japan. If any of these routes should
fail for some reason, our networks are designed to switch automatically
to another route. Moreover, our communications equipment has
been backed up and decentralized, and we monitor its performance
24 hours a day, 365 days a year, supporting network services
of consistently high reliability.
|
To ensure uncompromising reliability with support for
a broad range of operational modes, NTT Communications
centralizes the operation and management of its network
services. This centralization enables the Company to provide
its customers with unsurpassed levels of quality, efficiency
and reliability.
| (1) |
One-stop
customer service for resolution of product
failures |
|
With a single,
centralized contact point for resolution of
product failures, we respond quickly and attentively
to customer concerns. |
| (2) |
Monitoring
and control of equipment at network service
nodes |
|
Nationwide
monitoring 24 hours a day, 365 days a year assures
outstanding reliability in our network services. |
| (3) |
Quality
control tailored to individual customer
needs based on Service License Agreements
(SLA) and failure analysis reports |
|
NTT Communications
provides individually tailored quality control
and analysis reports. |
|
|
|

Offering a Global IP Network
|
|
As business goes increasingly multinational, our customers
demand global IT services. On the individual level, Japan’s
consumers are turning their attention ever more overseas, downloading
content and shopping online at sites based all over the world.
At NTT Communications, we work with our partners in Japan and
overseas to seamlessly blend domestic and international services
into a faultlessly stable and reliable online experience, backed
by a global Tier 1* IP backbone and data centers located worldwide.
The result is a service ideally suited to the age of ICT.
| *A “Global Tier
1” |
ISP is an ISP that possesses its own world-class
broadband backbone, with which it can control the quality
of its service without depending on upstream providers. |
 
In addition, our Global Network Operation Center delivers remote
monitoring and backup services, providing seamless maintenance
and assuring 24-hour end-to-end support. All inquiries from
emergency support to general consultation are concentrated in
a single customer service center, so customers can enjoy the
convenience, simplicity and efficiency of a onestop help desk.

At NTT Communications,
we are working constantly on research and development to
improve reliability.
GMPLS is a revolutionary network technology for the next
generation optical networks.
| Generalized Multi-Protocol
Label Switching (GMPLS) is an important network control
technology for the next generation of optical networks.
It is currently under development in the R&D departments
of telephone carriers and communication equipment
venders around the world, including NTT’s laboratories.
NTT Communications is keenly interested in GMPLS and
is conducting a development program of its own, which
culminated in May 2005 in a successful proving test
of a commercial network using GMPLS technology. With
GMPLS, NTT Communications looks forward to creating
intelligent networks which automatically seek out
and switch to a detour route when obstructions occur,
ensuring rapid, automatic recovery. |
|
The automatic detour and recovery features of GMPLS
were demonstrated to the public with this video link
between Interop Tokyo 2005, a technology fair held
in Makuhari Messe (International Convention Complex
near Tokyo), and Expo 2005 in Aichi. |
