SIST EN 301 483-2 V1.1.1:2005 PDF

Overview

SIST EN 301 483-2 V1.1.1:2005 defines the Abstract Test Suite (ATS) and the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the Advice of Charge (AoC) supplementary services over Private Integrated Services Network (PISN) inter-exchange signalling protocol. This standard-aligned with EN 301 483-2 and based on ISO/IEC 15049 (1997), as modified-specifies the methodology and key requirements for verifying conformance of telecommunications equipment implementing the AoC services in PISN environments.

This document supports the implementation and validation of AoC functionality, ensuring consistent interworking, testability, and compliance within private telephone networks that utilize the QSIG protocol for signalling between exchanges.

Key Topics

• Abstract Test Suite (ATS):

  • Specifies a comprehensive set of test cases to assess protocol compliance.
  • Outlines the mapping between test purposes and test case identifiers.
  • Describes the use of the multi-party test method, including the configuration of Points of Control and Observation (PCO).

• PIXIT Proforma:

  • Provides a standardized template for gathering supplementary protocol information needed for conformance testing.
  • Supports customization for specific implementations and environments.
  • Ensures accurate execution and interpretation of test results.

• Test Conventions:

  • Utilizes TTCN notation, with the integration of ASN.1 for type definitions and encoding rules (such as BER or ISDN direct encoding).
  • Guarantees traceability and repeatability in protocol conformance assessments.

• Reporting and Results:

  • Offers proforma templates for Protocol Conformance Test Reports (PCTR).
  • Details mandatory reporting structures for static and dynamic conformance summaries.
  • Encourages clear documentation of observations, limitations, and conformance verdicts.

Applications

This standard is essential for:

• Telecom Equipment Manufacturers:

  • Verifying that PISN products properly implement Advice of Charge supplementary services according to European standards.
  • Supporting the development of test plans and conformance strategies during product design.

• Testing Laboratories:

  • Applying the ATS and PIXIT proformas to create effective test campaigns.
  • Producing formal conformance documentation (PCTR) for regulatory or customer requirements.

• Network Operators and Integrators:

  • Ensuring deployed PISN equipment with AoC services interoperate reliably across different vendor solutions.
  • Supporting procurement and acceptance testing processes by referencing a harmonized standard.

• Quality Assurance and Certification Bodies:

  • Providing a benchmark for third-party assessment and interoperability testing in private telephone networks.
