Overview
SIST EN 300 058-6 V1.4.1:2004 provides a standardized framework for verifying conformance to the Integrated Services Digital Network (ISDN) Digital Subscriber Signalling System No. One (DSS1) protocol, especially in relation to the Call Waiting (CW) supplementary service. This document defines the Abstract Test Suite (ATS) and the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for network implementations. Issued by the Slovenian Institute for Standardization (SIST), this standard ensures harmonized and consistent ISDN supplementary service testing across European networks.
The main goal of this standard is to enable comprehensive and repeatable conformance assessments for ISDN network-side implementations, laying the foundation for enhanced service interoperability, reliable network behavior, and streamlined protocol testing.
Key Topics
- Abstract Test Suite (ATS): Specifies a set of abstract test cases, enabling consistent verification of DSS1 protocol implementations supporting Call Waiting services on the network side.
- Protocol Implementation eXtra Information for Testing (PIXIT) proforma: Provides a template for gathering information about specific implementation details required to conduct meaningful protocol tests.
- Conformance Assessment: Outlines requirements and reporting formats, such as the Protocol Conformance Test Report (PCTR) proforma, for documenting conformance test results.
- Test Methodology:
- Multi-party test concepts for realistic testing scenarios, covering multiple interfaces.
- Role definitions for master and slave test components to ensure targeted observation and verdict assignment.
- TTCN Notation: Use of Tree and Tabular Combined Notation (TTCN) as per ISO/IEC 9646-3 for specifying test suites.
- Change Tracking and Documentation: Includes annexes for documenting specification changes, ensuring traceability in revisions.
Applications
SIST EN 300 058-6 V1.4.1:2004 is essential for organizations developing, testing, or maintaining ISDN network-side products and services that utilize the DSS1 protocol, particularly where Call Waiting functionality is required. Practical applications include:
- Telecom Operators: Ensuring deployed network equipment conforms to European ISDN supplementary service standards for Call Waiting.
- Test Laboratories: Implementing repeatable, ETSI-aligned conformance tests using the specified ATS and PIXIT formats, and documenting results in standardized PCTR reports.
- Network Equipment Vendors: Verifying that their ISDN network products properly implement the DSS1 protocol for supplementary services, increasing customer confidence and regulatory compliance.
- Accreditation and Certification: Providing a foundation for independent testing, certification, and product approval processes within the telecommunications sector.
- Interoperability Testing: Facilitating integration and compatibility between multiple vendor solutions within ISDN networks.
Related Standards
This document is part of a broader set of ISDN standards. Organizations involved in protocol implementation and conformance testing should be aware of the following complementary standards:
- EN 300 058-1 (Protocol Specification): Defines the base protocol specification for Call Waiting using DSS1.
- EN 300 058-2 (PICS Proforma): Details the Protocol Implementation Conformance Statement proforma for Call Waiting.
- EN 300 058-5 (TSS & TP for the Network): Describes the Test Suite Structure and Test Purposes specification.
- EN 300 141-1 (Call Hold Supplementary Service): Covers the protocol for other essential ISDN supplementary services.
- ISO/IEC 9646 Series: Provides the general methodology and frameworks for OSI conformance testing, including abstract test suites and TTCN notation.
Adhering to SIST EN 300 058-6 V1.4.1:2004 improves product reliability, assists with regulatory requirements, and supports the seamless operation of ISDN-based telecommunications services across Europe.
