8、roup7 (1 997-2000) and approved on 3 1 March 2000. ITU-T X.228 (03/2000) 1 FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (U-T) is a permanent organ of ITU. ITU-T i
9、s 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 for study
10、 by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of U-T Recommendations is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within U-Ts purview, the necessary standards are prepared on a collab
11、orative 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 practice or impleme
12、ntation of this Recommendation may involve the use of a claimed Intellectual Property Right. U takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by U members or others outside of the Recommendation development process. As o
13、f 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 strongly urged t

X.209
16、I IS0 8825. Each encoded component shall contain Identifier and Length octets. A comparison between the session connection identifier element on an RTORQ APDU with the session connection identifier parameter of an (earlier) A-ASSOCIATE service primitive succeeds if the values of the three components
17、, ignoring the BER-derived identifier and length octets, are the same. It is a local matter how the responding RTPM performs this.
