E.106. This
8、amendment contains the modifications to ITU-T Rec. Q.763 (1999) in order to accommodate these needs. It should be read in conjunction with Amendment 3 to ITU-T Rec. Q.761, Amendment 3 to ITU-T Rec. Q.762, and Amendment 4 to ITU-T Rec. Q.764. This amendment incorporates Amendment 2 to ITU-T Rec. Q.76
9、3 and provides enhancements. Source Amendment 4 to ITU-T Recommendation Q.763 (1999) was approved on 27 January 2006 by ITU-T Study Group 11 (2005-2008) under the WTSA Resolution 1 procedure. ii ITU-T Rec. Q.763 (1999)/Amd.4 (01/2006) FOREWORD The International Telecommunication Union (ITU) is the U
10、nited Nations specialized agency in the field 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 tele
11、communications on a worldwide basis. The World 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
12、procedure laid down in WTSA Resolution 1. In 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
13、telecommunication administration and a recognized 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
14、 these mandatory provisions are met. The words “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
15、 ITU draws attention to the possibility that 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 m
16、embers or others outside of the Recommendation 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
17、 not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2006 All rights reserved.
