Full title and description
Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Route Restriction Class additional network feature. This International Standard specifies the signalling protocol details needed to support the Route Restriction Class additional network feature used between Private Integrated Services Network eXchanges (PINXs) at the Q reference point.
Abstract
ISO/IEC 13241:1997 defines the stage‑3 signalling protocol elements, message formats and procedures required to implement the Route Restriction Class additional network feature (an ANF) for QSIG‑based inter‑exchange signalling in Private Integrated Services Networks. The document focuses on interoperability at the Q reference point between PINXs to enable controlled routing and routing restrictions during call/connection setup.

Scope
The standard specifies the signalling protocol to support the Route Restriction Class additional network feature at the Q reference point between PINXs connected within a Private Integrated Services Network. It covers the protocol elements, parameter codings and signalling procedures required so that vendors and operators can implement interoperable support for route restriction behaviour (for example to prevent or limit routing through specific exchanges or to limit transit hops) as part of the QSIG family of inter‑exchange signalling standards.
Key topics and requirements
- Definition of the Route Restriction Class additional network feature (ANF) for QSIG Q‑point signalling.
- Stage‑3 signalling protocol specifications: message structures, parameter codings and error handling.
- Procedures for indicating and enforcing route restrictions during call/connection setup and routing decisions.
- Interoperability considerations for PINX‑to‑PINX signalling at the Q reference point.
- Conformance requirements sufficient for implementation testing and vendor interoperability.
Typical use and users
Primary users are telecommunications equipment manufacturers, PBX/PINX vendors, network integrators, enterprise telecom architects, and service providers that implement or interconnect Private Integrated Services Networks. Test laboratories and conformity assessment bodies also use this standard when validating QSIG inter‑exchange signalling features and supplementary services implementations.
Related standards
ISO/IEC 13241:1997 is part of the broader QSIG / PISN family of standards. Related and neighbouring documents include other ISO/IEC 1324x series items addressing B‑QSIG and basic call/connection control (for example ISO/IEC 13247 and ISO/IEC 13246) and subsequent QSIG interworking specifications (such as standards for QSIG↔SIP and QSIG↔H.323 interworking). Implementers typically consult ISO/IEC 11579‑1 (Q reference point definition) and the various QSIG service specifications when working with this standard.

Q: What does it cover?
A: It covers stage‑3 signalling details — message formats, parameter encodings and procedures — required to indicate and enforce routing restrictions during call/connection setup between PINXs using QSIG signalling.
Q: Who typically uses it?
A: PBX and PINX equipment vendors, telecom network operators and integrators, enterprise telecom architects, test labs and standards bodies involved in QSIG/PISN implementations and interconnects.
Q: Is it current or superseded?
