CCITT - IVth Plenary Assembly (Mar del Plata, 1968)

14 - 25 October 1968 - Mar del Plata, Argentina

What is an Assembly?

Assemblies provide overall direction to the activities of ITU’s standardization and radiocommunication sectors (formerly the International Consultative Committees – CCIF, CCIT, CCITT, CCIR). They approve a list of technical subjects related to telecommunications (called Questions) and refer them to a number of Study Groups composed of experts from different countries. They establish or disband Study Groups according to need and elect the chairs and vice-chairs for the groups. Assemblies also adopt the Recommendations developed by their sector’s Study Groups. For more information about the standardization sector and its history, visit the Focus on Standardizaton page.
