ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU
Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. Some 179 member countries, 84 telecom
operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the
body which sets world telecommunications standards (Recommendations).
The approval of Recommendations by the Members of ITU-T is covered by the procedure laid down in WTSC Resolution No. i
(Helsinki, i 993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years,
approves Recommendations submitted to it and establishes the study programme for the following period.
In some areas of information technology which fall within ITU-T’s purview, the necessary standards are prepared on a collaborative
basis with IS0 and IEC. The text of ITU-T Recommendation X.237, Amendment 1, was approved on 5th of October 1996. The
identical text is also published as ISODEC International Standard 10035-1.
