Title: International Standardization of Cable Modem and Technical Trend of IP Telephony
Presenter: Mayumi Matsumoto(NEC Magnus Communications, Ltd.
Engineering Senior Manager, 2nd Engineering Department Rapporteur and WG8 Chair for ITU-T SG9)
Location: Faculty of Engineering, Kumamoto University
Abstract: First, recent standardization activity of ITU-T (International
Telecommunications Union) SG9 (Study Group 9) is presented. The mandate of SG9 is the study for "Integrated Broadband Cable Networks and Television and Sound Transmission". Secondly, development and standardization of cable modems are lectured from the view point of high-speed Internet connection and VoIP (Voice over IP) application over cable networks. Thirdly, after briefing of cable VoIP system and its signaling protocols, "A Guideline for IP Telephony" currently compiled by Ministry of Public Management, Home Affairs, Posts and Telecommunications is specifically explained.

Abstract Our work concentrate on the Digital Naming, which is the technique for automatically identifying objects in the real world and provides personal IDs for basic scheme for personal authentication in the information society. This lecture focuses mainly on the automatic
identification of objects using RFIDs (Radio Frequency Identification), and discusses the requirements for the Digital Naming to be social system infrastructure. Automatic identification using RFIDs is gathering attractions as the fundamental technology for realizing ubiquitous computing. However, current applications are mainly in the closed systems, which are applied at particular places, or in organizations. For open systems, the aspects of social system infrastructure must be well considered, and technology to match the requirements for social system infrastructure must be developed, as well as the efficiency and the costs of the Digital Naming.
