ITU-T ITU-T Standardization Areas Tatiana Kurakova, Telecommunication Standardization Sector Engineer 7 October 2003, Tashkent

ITU-T 2 Standardization Area: A complete project to be standardized through the standardization of every aspect required for the completion of the standardization activities required. This could be associated to the vertical standardization concept. Standardization Domain: The aspect or one of the aspects for which standardization activities are required for the completion of the standardization activities required by an Standardization area. This could be associated to the horizontal standardization concept. What are Standardization Areas and Domains?
