ITU-T RECOMMENDATION Q.2660 INTERWORKING BETWEEN SIGNALLING SYSTEM NO. 7 - BROADBAND ISDN USER PART (B-ISUP) AND NARROW-BAND ISDN USER PART (N-ISUP) Summary This Recommendation shows the mappinglinterworking between B-ISUP and N-ISUP for the basic
8、 call and supplementary services. Source ITU-T Recommendation 4.2660 was revised by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on 3 December 1999. Recommendation 4.2660 (12/99) 1 FOREWORD ITU (International Telecommunication Union) is the United Natio
9、ns Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (RU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecomm
10、unications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of th
11、e ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In 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 c
12、onciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU t
13、akes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual
14、 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 are therefore strongly urged to consult the TSB patent database, O ITU 2000 Ali rights reserved.

24、SDN USER PART (B-ISUP) AND NARROW-BAND ISDN USER PART (N-ISUP) (revised in 1999) IAA 4 IAM F 1 Scope This Recommendation specifies the interworking between Broadband ISDN User Part as used in the Broadband network and the Narrow-band ISDN User Part as defined in the 1997 Recommendations 1 O. Intenvo
25、rking of the basic call and supplementary services applicable to the international interface are included. Intenvorking is shown as arrow diagrams showing the message interworking, with tables being used to show the mapping of parameters. In some cases the message mapping is ambiguous. In those case
26、s, the actual state of the involved ASES has to be considered in addition to determining in which message the information is mapped. This is, however, outside the scope of this Recommendation. When repeated information elements are contained in B-ISUP parameters, on ascending order of priority is as
27、sumed. This Recommendation covers the following three interworking scenarios: - Broadband transit network; - Narrow-bandhoadband interworking; - Broadbandnarrow-band interworking. The interworking diagrams and tables show only the case of the broadband network being a transit network between two nar
28、row-band networks. However, the information given is also relevant to the narrow-bandhoadband and broadbandnarrow-band interworking cases as indicated below. (See Figures 1 to 3.)
