Implementation
1. Build a next-generation network that is
open, flexible, easy-to-use , interoperable, and safe&secure
=> 30 million FTTH users by 2010
2. Strengthen our competitiveness and
financial base (Targets up to 2010)
- Annual additional sales: 5 billion US$
- Total capital expenditure: 50 billion US$
- Annual cost reduction: 8 billion US$

NGN vs PSTN & The Internet
PSTN
- High quality voice-centric
service
- Reliable and stable
- Public network managed
by established OSS
The Internet
- Various broadband
services
- Less expensive
- Distributed open network
architecture
Fusion
NGN (Secure and full-IP network)
- inherits high quality and reliability from PSTN
- exploits IP technology
- overcomes security issues

The Way to Regionalization
ITU/APT Workshop on NGN Planning, Bankok, 16-17 March 2006
(C)2007 NTT
14
Rationale for Regionalization
Globalization:
- basically market-oriented standardization
- difficult to reflect special needs if the market size
is small
Regionalization:
- collecting various requirements from many
countries/members
- classification of requirements into several classes
- each class becomes significant enough to be
standardized and more attractive to venders

What ASTAP/APT Should Do
So, what is required in Asia/Pacific?
to make regional consensus for e.g., cheap
broadband access
to encourage ITU-T and De-Facto
proposing it as our regional requirements
to learn the success story of GSM developed
by ETSI is essential (they’re paving the
similar way for NGN standardization)
