ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on t

9、hem with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the U-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T

10、 Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of idormation technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used f
