The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. Annex A to ITU-T Recommendations Q.601-Q.695 was revised by the ITU-T Study Group XI (1988-1993) and wasapproved by the WTSC (Helsinki, March 1-12, 1993).
