ITU-T RECOMMENDATION 4.953.5 STAGE 3 DESCRIPTON FOR CALL COMPLETION SUPPLEMENTARY SERVICES USING DSS1: CALL COMPLETION ON NO REPLY (CCNR) Summary This Recommendation specifies the stage three
7、 of the Call Completion on No Reply (CCNR) supplementary service for the Integrated Services Digital Network (ISDN) at the T reference point or the coincident S and T reference point by means of the Digital Subscriber System No. 1 (DSS1) protocol. Stage three identifies the protocol procedures and s
8、witching functions needed to support a telecommunication service. The CCNR supplementary service enables a calling user A, encountering a destination B which does not answer the call (No Reply), to be notified, when the destination B becomes not busy after having initiated an activity. If user A des
9、ires, then the network will reinitiate the call to the specified destination B. This Recommendation includes an electronic attachment containing the SDL diagrams in reprocessable SDT format. Source ITU-T Recommendation 4.953.5 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under t
10、he WTSC Resolution No. 1 procedure on 3 December 1999. Recommendation 4.953.5 (12/99) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (U-T) is a permanent organ of the
11、 ITU. The U-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 Conference (WTSC), which meets every four years, establishes the t
12、opics 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 the 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 purvie
13、w, 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 recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws at
14、tention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The U takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by U members or oth
15、ers outside of the Recommendation development process. As of the date of approval of this Recommendation, the U 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 repres
16、ent the latest information and are therefore strongly urged to consult the TSB patent database. o mu 2000 All rights reserved.
