Overview
SIST EN 302 092-4 V1.1.1:2005 defines the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for call control protocols used in Broadband Integrated Services Digital Network (B-ISDN) and Broadband Private Integrated Services Network (B-PISN) environments. This standard applies to the testing of call control protocol implementation conformance in environments where call and bearer controls are separated, specifically referencing the Digital Subscriber Signalling System No. two (DSS2) and Broadband QSIG (B-QSIG) protocols.
By providing standardized ATS and PIXIT documentation, this part of the EN 302 092 series ensures consistency and reliability in conformance testing for network equipment manufacturers, service providers, and testing laboratories.
Keywords: Abstract Test Suite (ATS), PIXIT, B-ISDN, B-PISN, DSS2, B-QSIG, call control, conformance testing, protocol assurance
Key Topics
Abstract Test Suite (ATS) Implementation:
The standard specifies the structure and requirements for an ATS, enabling systematic and reproducible testing of call control protocols as deployed at QB, SB, TB, and co-incident SB/TB reference points. The ATS is based on the Tree and Tabular Combined Notation (TTCN).Partial PIXIT Proforma:
PIXIT documents protocol-specific extra information required for testing, focusing on implementation characteristics needed for the preparation and customization of test executions.Test Methodology:
The document aligns with international testing frameworks (ISO/IEC 9646 series), detailing multi-party and remote test strategies. It covers conventions for test components such as Main Test Component (MTC), Parallel Test Component (PTC), and Points of Control and Observation (PCO).Protocol Conformance Test Reporting (PCTR):
Annexes provide standardized reporting formats to summarize the outcome and environment of protocol conformance tests, ensuring transparency and repeatability.Reference Interfaces:
Applicable interfaces within and between public and private broadband networks are addressed, supporting both end and transit call control entities.
Applications
Conformance Testing of Network Equipment:
Essential for manufacturers developing B-ISDN or B-PISN devices, the ATS and PIXIT support objective evaluation of DSS2 and B-QSIG implementations for protocol compliance. This reduces interoperability issues in carrier, enterprise, and multi-vendor environments.Test Laboratory Accreditation and Practice:
Testing facilities use the defined ATS and PIXIT proforma to develop or augment their test suites, ensuring adherence to European and international telecommunications standards.Product Certification:
Telecommunications product vendors leverage these specifications during certification processes to demonstrate protocol compatibility, supporting market access and regulatory approval.Protocol Development and Maintenance:
Protocol designers and maintenance teams utilize the standard for regression testing, enhancements, and quality assurance for broadband ISDN and private ISN call control protocols.
Related Standards
For comprehensive protocol testing and integration, the following standards are referenced and should be consulted:
- EN 302 092-1: Protocol specification for call control in separated call and bearer control environments.
- EN 302 092-2: Protocol Implementation Conformance Statement (PICS) proforma specification.
- EN 302 092-3: Test Suite Structure and Test Purposes (TSS&TP) specification.
- ISO/IEC 9646 Series: International standards framing the methodology and protocols for Open Systems Interconnection conformance testing.
- Other relevant B-ISDN and QSIG specifications as required for detailed protocol or interface alignment.
Adherence to SIST EN 302 092-4 V1.1.1:2005 streamlines the implementation, verification, and certification of broadband call control protocols, supporting robust interoperability and quality within advanced digital networks.
