Overview
SIST EN 301 067-4 V2.1.1:2003 specifies the Abstract Test Suite (ATS) and partial Protocol Implementations eXtra Information for Testing (PIXIT) proforma for the user side of the Digital Subscriber Signalling System No. two (DSS2) protocol, which operates within the context of the Broadband Integrated Services Digital Network (B-ISDN). Part 4 of this standard aligns and complements the previous parts by providing structured, standardized approaches for protocol conformance testing during the negotiation phase of B-ISDN call or connection establishment. The standard is published by the Slovenian Institute for Standardization (SIST) and is identical to EN 301 067-4 V2.1.1.
This document is crucial for implementers, testers, and laboratories seeking to ensure interoperability and adherence to the DSS2 protocol at the user–network interface. It delivers both the framework and specific tools required for rigorous, repeatable protocol testing, in compliance with international methodologies.
Key Topics
- Abstract Test Suite (ATS): The standard provides a comprehensive and methodical ATS for testing the DSS2 protocol's conformance at the user interface. It employs Tree and Tabular Combined Notation (TTCN) as specified in ISO/IEC 9646-3.
- PIXIT Proforma: It includes a partial PIXIT proforma, allowing for unique information (such as environmental and implementation-specific details) to be captured and utilized during testing.
- Protocol Conformance Test Reporting: A detailed Protocol Conformance Test Report (PCTR) proforma is supplied, streamlining the documentation and assessment of test results.
- Test Management: Guidance is provided for test campaign management, including configuration items, timer values, and parameter ranges to cater for various implementation scenarios.
- Conformance Requirements: The standard specifies compliance with conformance testing methodology as per the ISO/IEC 9646 series, ensuring international alignment and acceptance.
Applications
- Protocol Conformance Testing: Test laboratories and product manufacturers use the ATS and PIXIT to plan, execute, and document conformance assessments for B-ISDN DSS2 implementations at the user-network interface.
- Interoperability Assurance: By following the defined test suite and procedures, industry stakeholders can ensure that new installations or updates to DSS2-based network equipment will operate correctly within a B-ISDN environment.
- Certification Processes: The standardized reporting formats and configurable test parameters support formal certification activities for telecommunication protocols.
- Development and Debugging: Developers can employ the provided abstract tests and proformas during product development to identify non-conformance and support rapid troubleshooting.
- Network Upgrades: Service providers evaluating upgrades or changes to B-ISDN user interfaces can utilize this standard to verify continued compliance and performance.
