2、TION - TRANSPORT SERVICE DEFINITION ITU-T Recommendation X.214 (Previously “CCITT Recommendation“) ITU-T RECMN*X-214 75 4Ab2591 0b12b75 410 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Stan
3、dardization 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).
4、 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 World Telecommunication Standardization Conference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes
5、 the study programme for the following period. In some areas of information technology which fall within IT-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. The text of ITU-T Recommendation X.214 was approved on 21st of November 1995. The identical text is
6、also published as ISOLEC International Standard 8072. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
