Source ITU-T Recommendation 4.1912.4 was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 2 July 200 1. ITU-T 4.1912.4 (07/2001) i FOREWORD The International Telecommu

8、nication Union is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standarhtion Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tarif questions and issuing Recommendations on them with a view to

9、 standardizing telecommunications 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

10、 is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fail 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

11、to indicate both a telecommunication administration and a recognized 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 Intelledual Property Right. ITU takes no position co

12、ncerning the evidence, validity or applicability of claimed Intellectual Properly Rights, whether asserted by IT 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

13、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 to consult the TSB patent database. o ITU 2002 Au rights reserved.

16、m No. 2 (DSS2). In this Recommendation, interworking is defined through the relationships in existing Recommendations for interworking between DSS2 and B-ISUP, in addition to interworking between B-ISUP and ISUP. BICC is the protocol defined in ITU-T 4.1902.1 to Q.1902.4 6. DSS2 is defined by ITU-T

17、4.2931 15, 4.2932.1 17, 4.2951 18, 4.2951.9 is, 4.2957 20, 4.2941.2 21. B-ISUP is the protocol defined in ITU-T 4.2761 to 4.2764 14. ISUP is the protocol defined in ITU-T 4.761 to 4.764 4. This Recommendation builds on: - The signalling interworking between existing DSS2 and the B-ISDN User Part (B-

18、ISUP) protocol as defined in various ITU-T Recommendations. The signalling interworking between existing B-ISUP signalling systems and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in various IT-T Recommendations. The signalling interworking between the Bearer Independent

19、Call Control (BICC) protocol and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in IT-T 4.1912.1 7. - - The scope of this Recommendation as shown in Figure 1.

33、commendation specifies the interworking principle between BICC and Digital Subscriber Signalling System No. 2. The interworking is defined by the concatenation of information provided by several ITU-T Recommendations that are part of a set of interlocking B-ISDN service and signalling Recommendation

34、s that comprise broadband signalling capabilities. Figure 2 provides the functional grouping of the entities involved. The B-ISDN access signalling DSS2 is specified in ITU-T 4.2931 16. The interworking between DSS2 for 64 kbits circuit mode services and BICC shall act according to the interworking
