8、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 organi
9、zations 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. 1 (Helsinki, 1993). In addition, the
10、 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 prep
11、ared on a collaborative basis with IS0 and IEC. The text of ITU-T Recommendation X.227, Amendment 1, was approved on 5th of October 1996. The identical text is also published as ISO/IEC International Standard 8650-1. NOTE In this Recommendation, the expression ?Administration? is used for concisenes
12、s to indicate both a telecommunication administration and a recognized private operating agency. O ITU 1997 All rights reserved.
