9、ar down. Source ITU-T Recommendation 4.2650 was revised by ITU-T Study Group 11 (1997-2000) and approved under the WTSA Resolution 1 procedure on 3 December 1999. ITU-T 4.2650 (12/1999) 1 FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field o
10、f 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 World
11、Telecommunication Standardization Conference (WTSC), 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 WTSC 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 IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recogn
13、ized operating agency. INTELLECTUAL PROPERTY RIGHTS 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 Inte
14、llectual Property Rights, whether asserted by ITU members 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
15、. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2001 All rights reserved.

27、rworking between signalling system No. 7 broadband ISDN user part (B-ISUP) and digital subscriber signalling system No. 2 (DSS2) 1 Scope This ITU-T Recommendation defines the intenvorking relationship between the layer 3 functions and protocol of the B-ISDN DSS2 Access Interface and the B-ISDN User
28、Part functions and protocol of Signalling System No. 7. For the purpose of this intenvorking, B-ISUP is defined in ITU-T Recommendations 4.2761-4 and 4.2730. For the purpose of this intenvorking, DSS2 is defined in ITU-T Recommendations 4.293 1, 4.2933, 4.2961.1-6, 4.2962, 4.2963.1-3, 4.2951, 4.295
29、1.9 and 4.2957. The intenvorking between the above two signalling protocols typically may occur in a B-ISDN local exchange and is specified in the context of a typical call in a pure B-ISDN environment. Support of 64 kbitls narrow-band emulation services is included. The objective of this ITU-T Reco
30、mmendation is to specify the intenvorking between the Broadband ISDN User Part protocol and the DSS2 protocol. Intenvorking is shown as message arrow diagrams. Due to the multiplicity of optional possibilities in both the B-ISDN User Part and the DSS2 protocol, not all possible cases are shown in ar
31、row diagrams. The diagrams included represent a sample of typical situations. Mapping tables are provided to define the relationship between DSS2 protocol messages and information elements, on the one hand, and B-ISDN User Part messages and parameters on the other hand. Tables are provided for each
32、DSS2 protocol message that maps onto a B-ISDN User Part message. These tables also specify the mapping of elements of information which are carried by the concerned messages. The elements of information that are of local significance only, i.e. are not mapped onto elements of information in the othe
33、r signalling system, are not shown. The arrow diagrams used in this Recommendation show the message movement for intenvorking the call control protocols of DSS2 and B-ISUP. The working inside of the exchanges will not be shown, but rather the external stimulus to the exchange only. 2 References The
