ISO/IEC 13868:2003 PDF

Overview

ISO/IEC 13868:2003 - "Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Inter‑exchange signalling protocol - Name identification supplementary services" - defines the QSIG signalling protocol at the Q reference point for name‑presentation features in Private Integrated Services Networks (PISNs). The standard specifies support for the supplementary services Calling Name Identification Presentation (SS‑CNIP) and Connected Name Identification Presentation (SS‑CONP) between Private Integrated services Network eXchanges (PINXs). It is a stage‑3 service specification (per ETS 300 387) and complements stage‑1/2 requirements in ISO/IEC 13864.

Key topics and technical requirements

• Scope: Signalling protocol for name identification services (SS‑CNIP and SS‑CONP) at the Q reference point between PINXs. Provisioning of a user’s name to the PISN is out of scope.
• Services defined:
  • SS‑CNIP - delivers the calling party name to the called user.
  • SS‑CONP - delivers the connected party name (and optionally alerting or busy party names) to the calling user.
• ASN.1 operations: Encodings and operations are defined in ASN.1 (callingName, calledName, connectedName, busyName) with APDU mapping for inter‑exchange signalling.
• Name data: A name is a string up to 50 octets. Default character set is ISO‑8859‑1, with support for additional ISO/IEC 8859 sets and ISO/IEC 10646 (UCS).
• Conformance & testing: Protocol Implementation Conformance Statement (PICS) proforma provided in an annex to verify PINX compliance.
• Interworking and interactions: Specifies behavior for transit/gateway PINXs and interactions with other supplementary services (call forwarding, call transfer, CCBS/CCNR, path replacement). Notably, Calling/Connected Name Identification Restriction (CNIR) does not affect Q‑point signalling.
• Deliverables: Includes SDL representations, ASN.1 definitions and PICS proforma (annexes A–C).

Practical applications and users

Who benefits:

• PBX/PINX manufacturers implementing QSIG name presentation features.
• Telecom equipment vendors building inter‑exchange signalling stacks.
• System integrators and network architects designing enterprise PISNs with unified caller/connected‑name services.
• Test labs and compliance teams validating Q reference point interoperability and PICS conformance. Use cases:
• Enterprise caller‑ID and connected‑name display across multi‑site private networks.
• Inter‑PBX QSIG deployments requiring consistent name presentation and interworking with public ISDN or non‑ISDN gateways.
• Product certification and interoperability testing for QSIG name services.
