9、igendum 2 to ISO/IEC 1 O 164-2. IT-T X731(1992)/Cor.2 (01/2001 E) 1 FOREWORD The International Telecommunication Union 0 is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of . ITU-T is responsibl
10、e for studying technical, operathg and tariff questions and issuing Recommendations on them 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 IT-T st
11、udy groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within IT-Ts purview, the necessary standards are prepared on a collaborative basis
12、 with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS draws attention to the possibility that the practice or implementation of this R
13、ecommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by lT members or others outside of the Recommendation development process. As of the date of
14、approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, impiementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the
