Overview
SIST EN 301 068-4 V1.1.1:2003 outlines the requirements and specifications for the Abstract Test Suite (ATS) and the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the user side of the Digital Subscriber Signalling System No. two (DSS2) protocol within the Broadband Integrated Services Digital Network (B-ISDN). Developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with the European standard EN 301 068-4, this document ensures standardized conformance and test procedures for ATM transfer capability and traffic parameter indication at the user-network interface.
This part 4 of the series is essential for those involved in protocol implementation, conformance testing, and system integration of DSS2 in B-ISDN, addressing specifically the Abstract Test Suite and PIXIT for the user-side implementations.
Key Topics
Abstract Test Suite (ATS):
- Provides a formal framework for testing DSS2 protocol conformance on the user-side of the B-ISDN interface.
- Facilitates repeatable, clear, and meaningful testing processes using standardized methodologies.
- Employs Tree and Tabular Combined Notation (TTCN) for test case specification.
Partial PIXIT Proforma:
- Supports test customization and documentation by collecting essential extra information regarding the system under test.
- Aids test laboratories in preparing and executing relevant test scenarios.
Conformance Methodology:
- Details remote test methods with explicit Points of Control and Observation (PCOs) at specific protocol layers.
- Specifies requirements for Protocol Conformance Test Report (PCTR) and conformance status reporting.
Integration with International Testing Standards:
- Aligns with ISO/IEC 9646 for testing methodology, test suite development, and laboratory requirements.
- Considers relevant ITU-T recommendations for B-ISDN and DSS2 protocol implementation.
Applications
The practical value of SIST EN 301 068-4 V1.1.1:2003 lies in its ability to:
Facilitate Interoperability:
- Ensures consistent implementation and behavior of DSS2 protocol across diverse user equipment in B-ISDN environments.
- Reduces risk of interoperability issues by providing a reference framework for protocol conformance testing.
Support Test Laboratories and Vendors:
- Used by test labs to design and conduct robust conformance assessments for user-side DSS2 implementations.
- Serves equipment manufacturers, network integrators, and service providers seeking certification or validation of B-ISDN products.
Streamline Testing Processes:
- Provides reusable templates for ATS and PIXIT documentation, minimizing setup time and promoting best practices.
- Enables systematic reporting of test results, static and dynamic conformance, and environment details.
Related Standards
Organizations working with SIST EN 301 068-4 should also consider these key related standards:
- EN 301 068-1: DSS2 protocol specification for ATM transfer capability in B-ISDN.
- EN 301 068-2: Protocol Implementation Conformance Statement (PICS) proforma specification.
- ISO/IEC 9646 Series: International methodology for OSI conformance testing (including test suite and laboratory requirements).
- EN 300 443-1/2: Related B-ISDN and DSS2 protocol specifications and PICS proforma.
- ITU-T Recommendation I.413: B-ISDN user-network interface fundamentals.
Keywords: B-ISDN, DSS2, Abstract Test Suite, PIXIT, protocol conformance testing, ATM transfer capability, user network interface, integrated services digital network, protocol implementation, test laboratory, TTCN.
By conforming to SIST EN 301 068-4 and related standards, organizations ensure that their network implementations meet established European and international requirements, resulting in more reliable, interoperable, and high-quality digital communication services.
