Q.2941.2 in particular) subsequent to the approval of ITU-T Rec. H.310 (09/98). The essential point of this corrigendum is that
8、 the identifier type codepoint “00000011“ was formally defined by ITU-T Rec. Q.2941.2 after ITU-T Recs H.310 and Q.2941.1 had been published The mechanism of GIT (Generic Identifier Transport) is identified in ITU-T Rec. Q.2941.1, and ITU-T Rec. H.310 refers to it in Annex C.

9、 ITU-T Recommendation H.310 (1998) was approved on 8 January 2005 by ITU-T Study Group 16 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. H.310 (1998)/Cor.1 (01/2005) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the fiel
10、d of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. 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 Wor
11、ld Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics 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 WTSA Resolution 1. In
12、 some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recog
13、nized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The wor
14、ds “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that
15、 the practice 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 Recommendati
16、on development 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 ar
17、e therefore strongly urged to consult the TSB patent database. ITU 2005 All rights reserved.
