CSA ISO/IEC 13864:97 (R2020)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the IS0 member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This International Standard was reviewed by the CSA TClT under the jurisdiction of the Strategic Steering ommittee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Committee Administrator.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TClT will review these documents for approval and publication. For a listing, refer to the CSA Information Products Catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope This International Standard specifies the supplementary services Calling Name Identification Presentation (SS-CNIP), Connected Name Identification Presentation (SS-CONP) and Calling/Connected Name Identification Restriction (SS-CNIR), which are applicable to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574. Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user and which provides the name of the calling user (calling party name) to the called user. Connected Name Identification Presentation (CONP) is a supplementary service which is offered to the calling user and which provides to the calling user the following: - the name of the user who answers the call (connected party name); - optionally the name of the alerting user (called party name); - optionally the name of the called user who cannot be reached (busy party name). Calling/Connected Name Identification Restriction (CNIR) is a supplementary service which is offered to a user to restrict presentation of that user\'s name to another user. Service specifications are produced in three stages, according to the method described in CCITT Recommendations I.130. This International Standard contains the stage 1 and 2 specifications of the Name Identification supplementary services. The stage 1 specifications (clauses 6, 7 and 8) specify the supplementary services as seen by users of PISNs. The stage 2 specifications (clauses 9, 10 and 11) identify the functional entities involved in the supplementary services and the information flows between them.
