ISO/IEC 13864:1995

Overview

ISO/IEC 13864:1995 - "Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Specification, functional model and information flows - Name identification supplementary services" - defines the Name Identification Supplementary Services for Private Integrated Services Networks (PISNs). It uses ISDN concepts from ITU‑T and aligns with the OSI framework. The standard contains Stage 1 (service definitions from a user perspective) and Stage 2 (functional model and information flows) specifications for name presentation and restriction services.

Key topics and requirements

• Supplementary services covered
  • SS‑CNIP: Calling Name Identification Presentation - delivers the calling party name to the called user.
  • SS‑CONP: Connected Name Identification Presentation - provides the connected (answering) party name to the caller and optionally alerting or busy party names.
  • SS‑CNIR: Calling/Connected Name Identification Restriction - allows users to restrict presentation of their name.
• Service staging
  • Stage 1: user-visible behaviour, procedures (provision, activation, invocation, exceptions).
  • Stage 2: functional entities, allocation, and detailed information flows (INFORM messages and relationships to basic call flows).
  • Stage 3 (not included): required to specify signalling protocols and equipment behaviour for conformance.
• Notable technical details
  • Name string: up to 50 characters (structure in Annex A).
  • SS‑CNIP is generally permanently activated; no user registration required.
  • The PISN may truncate names to fit receiving capability; directory management and name acquisition methods are outside the standard’s scope.
  • Exceptions: names are not presented when CNIR is invoked or when name information is unavailable (interworking issues or no registration). In some override cases (e.g., emergency/operator profiles), presentation may include an indication that restriction was invoked.
• Interactions and interworking
  • Describes interactions with other supplementary services and ANFs such as CLIP, COLP, CLIR, call forwarding, call transfer, CCBS/CCNR, path replacement and interworking for incoming/outgoing calls.

Applications and who uses this standard

• Telecommunications equipment vendors (PISN/PINX, private exchange/PBX manufacturers) implementing name presentation features.
• Network operators and service designers defining subscriber services and service profiles.
• Standards developers and integrators creating Stage 3 signalling protocols and conformance tests.
• System architects mapping functional entities to physical components in PISN deployments.
