The lifetime of NTT’s PSTN facilities
NTT’s PSTN consists of about thousands switches.
Although a then-state-of-art switching system was developed around 10 years ago, the
rapid progress in technology since then has resulted in the discontinuation of
production of some components used in the system. Currently, we are trying to
prolong the lifetime of the switches by re-establishing sources for such components.

The revenue structure of the NTT Group
Revenue from traditional networks, such as the PSTN, is falling. This fall has not
yet been made up for by revenue from broadband businesses.
It is necessary to change the revenue structure by expanding revenue from
Broadband services provided on the NGN.

Increase in ARPU of broadband services
(ARPU : Average Revenue Per User)
• The bundled service of FTTH records a higher ARPU than POTS service.
• Since FTTH services can incorporate video delivery & other supplementary
services, the ARPU is increasing gradually.
・ It is urgent to raise ARPU further to strengthen our financial basis.

Promotion of optical access by the u-Japan Strategy
The Japanese government’s “u-Japan” plan proposes the full development of
broadband infrastructure by installing optical fiber networks nationwide.
Proposed status of broadband networks in 2010
Proposed on Aug. 11, 2006
1. 100% broadband network
The projected status of a 100% broadband network, through which broadband services are
made available to all communities, is as follows:
(1) Overall, a variety of wireline and wireless technologies will be seamlessly linked, and
broadband service based on one or more of these technologies will be available
nationwide.
(2) In areas where cost-effective investment is difficult, broadband infrastructure will be
built taking both investment efficiency and the needs of communities into account.
Specifically, the following will be used in addition to ADSL and cable modems:
(a) Wireless broadband using wireless LAN and other technologies;
(b) Integrated broadband, in which “wireless and ADSL/VDSL”, “optical fiber and
infrared transmission”, or “optical fiber and ADSL (in so-called Fiber To The RT
(FTTR))” are integrated.
(3) Of these varieties of broadband service, super-high-speed broadband access, mostly
based on FTTH, will cover 90% of households nationwide.

NTT’s share (%)
Share of FTTH, prefecture by prefecture
NTT has over 50% share in optical access nationwide. However, in urban areas,
where fibers can be installed efficiently, NTT faces tough competition and is
falling behind in many prefectures.

Rapid reduction in the charge for broadband access
•Strong competition has led to a price war, bringing down the charges for ADSL
and even FTTH dramatically.
•Strong competition has made it hopeless to seek to gain significant revenue
from telecommunication traffic.

Questions for launching the NGN
There are two questions regarding the launch of the NGN
• Chicken or egg?
Which comes first? (or, Highway or sports car?)
NTT may appear to be looking at infrastructure alone.
However, NTT’s approach is based on synchronizing
development of services and infrastructure
• From where do subscribers migrate ?
What is the subscriber base ?
BT:
Migrate from PSTN
Europe: Migrate from GSM world
NTT: Migrate from IP broadband

Summary
NTT’s history and plan for the NGN
z Since NTT first provided an IP network service for Internet
access, NTT has promoted optical access and triple play
services.
z To meet its timetable to get a 9M optical access subscriber
base and establish revenue source from triple play, NTT has
just started NGN commercial service.
z The NGN started in limited areas such as Tokyo and Osaka
as an upgrade of the existing IP network service.
z The NGN will cover a wide area in short time frame and
create new services aimed at new business areas.
NTT’s approach to launching the NGN
z NTT’s approach is based on synchronizing the development
of services and infrastructure.
z NTT’s subscriber base and revenue source will be migrated
from IP broadband to the NGN
