Whats TTC ?

• Establish protocols and standards
• Private non-profit organization accredited by
• the Ministry of Posts and Telecommunications
  
• Membership is open to any company and
  individuals
• Supported by the voluntary efforts of members

Presently MPHPT Ministry of Public Management,
Home Affairs, Posts and Telecommunications

• Establishment of TTC
• Trigger
• Deregulation of Telecom Market in Apr. 1985
• Japan/Us Market Oriented Sector Service(MOSS)
• Conference in 1985
• Establishment of TTC in Oct. 1985
• Fairness
• Transparency (Open)
• Efficiency
• Independence
• Dissemination of standards

Why TTC standardize ? 1. International standard
is compromise and full set having sometimes
too many options Select necessary
options 2. International standard does not
always reflect Japanese market
demands/requirements Develop TTC Original
standard (JJ standard) 3. International
standard is sometimes vague which can
misread and mislead users Create guideline and
explanation (Supplement)

Topics on Organizational Aspects

• Technical Bodys Structural Reform (December,
  2002)
• Review of TTC standardization procedure and
  operations
• IPR Policy
• Revisions of Policy
• Revision of Operation Procedures (April, 2003)
• Continuing work (Software copy right,
  Collaborated patent application, Copy right of
  contribution, Duty to protect privileged
  information, etc.)
• Introduction of Paperless Meeting
• Equipped each meeting room in TTC with PC
  projector,
• wireless LAN and laptop PCs
• Delivery of meeting documents by e-mail and FTP

7
Approach to Structural Reform

• Extensively review the way Technical Committees
  and other groups are organized.
• Organize Technical Committees and other groups in
  such a way that they can swiftly catch up with
  changing times.
• -- Top-down functions
• -- Simple hierarchical structures
• Allow for committee activities linked with those
  of the GSC, NGN, and others.

Survey and Study of Standardization Trends in the
World on NGN

• Based on participation of
• ITU-T Workshop on IP/Optical, ITU-T SG13,
  Committee T1 VoIP Signaling Summit,
• ATIS Security Summit, ETSI TIPHON (28, 30),
  Internet Society,
• IETF at Yokohama (54), ATM Forum at Prague
• Some Points
• Will NGN be realized based on the evolution to
  the convergence of the
• Internet and PSTN?
• Or will NGN be realized by introducing networks
  different from the
• Internet ? ? Smooth transition from
  PSTN
• Security, QoS, Lawful Interception,
  Network Management,
• Financial aspects
• VoIP, as a low cost infrastructure
