Overview
SIST EN 302 646-3:2000 specifies the Test Suite Structure and Test Purposes (TSS&TP) for the application of ISDN User Part (ISUP) version 3 at the signalling interface between Integrated Services Digital Network (ISDN) and Public Land Mobile Network (PLMN). Developed under the authority of the Slovenski inštitut za standardizacijo (SIST) and aligned with ETSI EN 302 646-3, this standard is a critical component of ensuring compatibility and validation between telecommunications nodes implementing the ISUP v3 protocol, particularly as defined in the REN/SPS-01039 and DE/SPS-01029-2 series.
SIST EN 302 646-3:2000 focuses on the validation and conformance testing required for reliable interworking between ISDN and cellular networks, leveraging the Signalling System No. 7 (SS7) protocol family. The document details standardized test configurations, abstract test methods, and a comprehensive suite of conformance test purposes for ISUP v3 at the ISDN-PLMN interface. Supporting organizations include Telecom Éireann, Ericsson, Siemens, Telia, Telenor, and KPN.
Key Topics
- ISUP v3 at the ISDN-PLMN interface: Clarifies implementation requirements to support uniform operation and interoperability between ISDN and mobile networks via the SS7 protocol.
- Test Suite Structure (TSS): Outlines the organization and categorization of required test cases for ISUP v3 protocol validation.
- Test Purposes (TP): Defines targeted, scenario-based test objectives to confirm proper protocol behavior and network interworking.
- Abstract Test Methods (ATM) & Test Configurations: Describes logical arrangements and layers for systematic, vendor-neutral ISUP validation.
- Coverage of Supplementary Services: Ensures features such as Calling Line Identification Presentation (CLIP), Calling Line Identification Restriction (CLIR), Connected Line Identification Presentation (COLP), User-to-User Signalling (UUS), Malicious Call Identification (MCID), Conference Calling (CONF), and others are robustly tested.
- Conformance and Validation: Requirements are set to assure interoperability and compliance with the reference protocol specifications (GSM 09.14 and related series).
Applications
SIST EN 302 646-3:2000 is highly relevant for:
- Network Equipment Manufacturers: Ensuring their switching nodes, gateways, and mobile switching centers (MSCs) supporting ISUP v3 are compliant with international and European standards for ISDN-PLMN signalling.
- Telecommunications Operators: Validating new installations or upgrades, particularly in multi-vendor or cross-border interconnect scenarios between fixed and mobile networks.
- Test System Vendors: Developing, providing, and updating ISUP v3 conformance testing tools and services according to a standardized test suite structure.
- Certification and Compliance Bodies: Assessing implementations against conformance requirements to grant network compatibility certifications.
- Integration Projects: Facilitating smooth interworking in projects that combine legacy ISDN infrastructure with modern PLMN deployments.
Key value includes risk reduction during network integration, support for international roaming, and reliable provision of supplementary services across network boundaries.
Related Standards
The following standards complement and support SIST EN 302 646-3:2000:
- EN 300 646-1: Protocol specification for ISUP v3 at the ISDN-PLMN interface (core reference for protocol behavior).
- EN 300 356 Series: Broad specifications for ISUP v3, including supplementary and basic services for international interfaces.
- ETS 300 604: Requirements for interworking between PLMN and ISDN/PSTN.
- ISO/IEC 9646 Series: Open Systems Interconnection testing methodology, including general concepts and Implementation Conformance Statements (PICS).
- ITU-T Q.763: ISDN user part formats and codes.
- Abstract Test Suite (ATS) and PIXIT specifications: Further parts of EN 302 646 covering executable test details and implementation-specific information.
As part of the EN 302 646 suite, this standard ensures unified conformance testing for ISUP v3, supporting seamless and quality-driven communications across ISDN and mobile operator networks.
