Overview

SIST EN 301 067-6 V1.1.3:2003 defines the procedures and formats for testing network-side conformance with the Digital Subscriber Signalling System No. two (DSS2) protocol, specifically within Broadband Integrated Services Digital Network (B-ISDN) environments. It focuses on the Abstract Test Suite (ATS) and the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the network, supporting connection characteristics and negotiation procedures during the call or connection establishment phase. This standard is crucial for ensuring reliable interworking and standard compliance at the user-network interface, enabling multi-vendor interoperability and facilitating quality assurance processes in B-ISDN implementations.

Key Topics

The standard addresses the following key topics for the network side of DSS2 protocol conformance:

• Abstract Test Suite (ATS): Specifies the suite of abstract test cases for evaluating network protocol behaviors at the user-network interface, as defined by EN 301 067-1.
• Test Methods: Utilizes multi-party and remote test methods, focusing on the correct observation and control points in the protocol stack (e.g., monitoring at defined service access points).
• Partial Protocol Implementation eXtra Information for Testing (PIXIT): Describes the required supplementary information to be provided for system under test (SUT) configuration, parameter values, and test management.
• Protocol Conformance Test Report (PCTR): Provides proforma templates for documenting test results, IUT (Implementation Under Test) status, test environments, and campaign summaries.
• ATS to Test Purpose Mapping: Aligns test cases with defined test purposes to ensure comprehensive coverage.
• Conformance Requirements: Outlines procedures and reporting formats in accordance with international standards such as ISO/IEC 9646, governing OSI protocol conformance testing.

Applications

SIST EN 301 067-6 V1.1.3:2003 is designed for practical use in the development, deployment, and maintenance of B-ISDN networks implementing DSS2 signaling. Key applications include:

• Conformance Testing: Ensures that network equipment, such as switches and access nodes, complies with pan-European B-ISDN signaling standards for connection establishment and negotiation.
• Quality Assurance: Enables test laboratories and service providers to systematically evaluate product interoperability and reduce deployment risks.
• Certification and Accreditation: Supports regulatory and industry certification schemes for telecommunications equipment.
• Vendor Interoperability: Helps different manufacturers achieve seamless interworking at the user-network interface by adhering to common testing procedures and reporting formats.
• Network Upgrades: Assists operators in validating new software or hardware releases against formal protocol specifications and test cases.

Related Standards

This standard is part of a series for the DSS2 protocol and references several related standards and international recommendations, including:

• EN 301 067-1: Protocol specification for DSS2 in B-ISDN.
• EN 301 067-2: Protocol Implementation Conformance Statement (PICS) proforma.
• EN 301 067-4: ATS and partial PIXIT proforma for the user side.
• EN 301 067-5: Test Suite Structure and Test Purposes (TSS&TP) for the network.
• EN 300 443-1/2: DSS2 protocol for basic call and bearer control.
• ISO/IEC 9646 series: International framework for OSI conformance testing, including concepts, ATS specification, TTCN notation, and requirements for test laboratories.

Keywords: B-ISDN, DSS2 protocol, conformance testing, ATS, PIXIT, PCTR, network protocol, telecommunications standards, broadband signaling, interoperability, ISDN.

By implementing SIST EN 301 067-6 V1.1.3:2003, organizations enhance reliability, compatibility, and compliance across B-ISDN deployments in alignment with European and global telecommunication standards.
