Description (English):

ISO/IEC 11582:2002 defines the signalling protocol for the control of Supplementary Services and Additional Network Features (ANFs) at the Q reference point. The protocol is part of Private Signalling System no. 1 (PSS1), known informally as QSIG. The Q reference point exists between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN) and is defined in ISO/IEC 11579-1. Detailed procedures applicable to individual supplementary services and ANFs are beyond the scope of ISO/IEC 11582:2002 and will be specified by other standards for those services which are standardised and by individual manufacturers for proprietary services using the capabilities defined in ISO/IEC 11582:2002. ISO/IEC 11572 defines the Layer 3 protocol for circuit-switched call control at the Q reference point. ISO/IEC 11582:2002 defines additional protocol procedures, to be used in conjunction with those defined in ISO/IEC 11572 for the control of supplementary services and ANFs. NOTE 1 Typical examples of the application of these generic functional procedures to some supplementary services are provided in annex C, for explanatory and illustrative purposes only. NOTE 2 Specific supplementary services and Additional Network Features may require additional information transfer mechanisms which are service or feature specific and are beyond the scope of ISO/IEC 11582:2002.

Abstract

Overview

ISO/IEC 11582:2002 specifies the generic signalling protocol used at the Q reference point between Private Integrated services Network eXchanges (PINXs) in a Private Integrated Services Network (PISN). Part of Private Signalling System No. 1 (PSS1), commonly known as QSIG, this standard defines inter‑exchange procedures and protocol elements for the control of Supplementary Services and Additional Network Features (ANFs). It provides generic, flexible transport and dialogue mechanisms (APDUs) to support both call‑related and call‑independent signalling across multi‑vendor enterprise networks.

Key Topics and Requirements

Scope and conformance: Defines signalling requirements at the Q reference point; conformance is demonstrated via the Protocol Implementation Conformance Statement (PICS) in Annex A.
Protocol model: Application association, dialogue management and generic functional transport control (GFT‑Control) layered with ACSE, ROSE and DSE service elements.
APDU transport: Procedures for connection‑oriented and connectionless transport of Application Protocol Data Units (APDUs), including call‑related and call‑independent mechanisms.
Dialogue and notifications: Dialogue identification protocol to tie information flows into dialogues and support for notification services across PINXs.
Information encoding: ASN.1 definitions and BER/CER/DER encoding rules for information elements (Annex B and related clauses).
Manufacturer specifics: Mechanisms to include proprietary operations and manufacturer‑specific notifications while maintaining interoperability.
Interoperation with call control: Designed to be used in conjunction with ISO/IEC 11572 (Layer 3 circuit‑switched call control) and ISO/IEC 11579‑1 (PINX reference configuration).
Referenced service elements: Uses ACSE, ROSE and DSE service definitions; normative references include ITU‑T Q.932 and relevant ISO/IEC OSI documents.

Applications and Who Uses It

Enterprise telephony architects and network designers deploying PISNs and multi‑site PBX interconnects.
PBX and IP‑PBX manufacturers, gateway vendors and equipment implementers building QSIG‑compliant signalling stacks.
Systems integrators and interoperability test labs validating supplementary services (e.g., call transfer, forwarding, display features) across vendor boundaries.
Standards engineers mapping ISDN/OSI signalling to manufacturer‑specific ANFs while preserving cross‑network transparency.

Practical benefits include enabling transparent supplementary service behaviour across enterprise exchanges, coexistence of standard and proprietary features, and a structured approach to signalling for call‑independent services.
