8、 (B-ISUP) of Signalling System No. 7 Amendment 1 Support for the International Emergency Preference Scheme Summary This amendment was produced to meet the urgent need for the implementation of the International Emergency Preference Scheme (IEPS) as specified in ITU-T Rec. E.106. This amendment conta
9、ins the modifications to ITU-T Rec. Q.2762 (12/99) in order to accommodate these needs. This amendment should be read in connection with the related amendments to ITU-T Recs Q.2761, Q.2763, and Q.2764. Source Amendment 1 to ITU-T Recommendation Q.2762 (1999) was prepared by ITU-T Study Group 11 (200
10、1-2004) and approved under the WTSA Resolution 1 procedure on 29 December 2002. ii ITU-T Rec. Q.2762 (1999)/Amd.1 (12/2002) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization
11、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 World Telecommunication Standardization Assembly (WTSA), which meets e
12、very 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 some areas of information technology which fall within ITU-Ts purv
13、iew, 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 recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws atte
14、ntion 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 members or other
15、s 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 not represent
16、the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2003 All rights reserved.
