Source ITU-T Recommendation Y. 1 O1 was prepared by ITU-T Study Group 13

6、 (1 997-2000) and approved under the WTSC Resolution 1 procedure on 10 March 2000. FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The IT Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU

7、. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics

8、for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepare

9、d on a collaborative basis 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 ITU draws attention to the possibility that the practic

10、e or implementation of this Recommendation 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 ITU members or others outside of the Recommendation developme

11、nt process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore

12、strongly urged to consult the TSB patent database. o ITU 2001 All rights reserved.
