International Telecommunications Union

<body, standard> (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. Before 1993-03-01 ITU-T was known as CCITT. Every four years they hold plenary sessions where they adopt new standards; there was one in 1992. ITU works closely with all standards organisations to form an international uniform standards system for communication. Study Group XVII is responsible for recommending standards for data communications over telephone networks. They publish the V.XX standards and X.n protocols. V.21 is the same as EIA's EIA-232. V.24 is the same as EIA's EIA-232C. V.28 is the same as EIA's EIA-232D.

International Telecommunication Union

The ITU (French: Union Internationale des Telecommunications, UIT) is a specialized agency of the United Nations with responsibilities for developing operational procedures and technical standards for the use of the radio frequency spectrum, the satellite orbit, and for the international public telephone and telegraph network. ITU develops telecommunications standards in the form of recommendations covering all technical aspects of systems and equipment including interfaces, methods of operation and principles governing the fixing of tariffs and rates to be charged. There are over 160 member nations of the ITU. The Radio Regulations that results from ITU conferences have treaty status and provide the principal guidelines for world telecommunications. In the case of the U.S., they are the framework for development of the U.S. national frequency allocations and regulations. The ITU has four permanent organs: the General Secretariat, the International Frequency Registration Board (IFRB), the International Radio Consultative Committee (CCIR), and the International Telegraph and Telephone Consultative Committee (CCITT). The Union is located in Geneva, Switzerland. The Department of State is the U.S. member.

International Telecommunication Union

The International Telecommunication Union (French: Union Internationale des Télécommunications) is a specialized agency of the United Nations responsible for many matters related to information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, making it the first international organization. Doreen Bogdan-Martin is the Secretary-General of ITU, the first woman to serve as its head.

The ITU was initially aimed at helping connect telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly created United Nations to become a specialized agency within the UN system, which formally entered into force on 1 January 1949.

The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve telecommunication infrastructure in the developing world. It is also active in the areas of broadband Internet, wireless technologies, aeronautical and maritime navigation, radio astronomy, satellite-based meteorology, TV broadcasting, amateur radio, and next-generation networks.

Based in Geneva, Switzerland, the ITU's global membership includes 193 countries and around 900 businesses, academic institutions, and international and regional organizations.
