Overview

SIST EN 301 067-3 V1.1.3:2003 specifies the Test Suite Structure and Test Purposes (TSS&TP) for the user side of the Digital Subscriber Signalling System No. two (DSS2) protocol, focused on connection characteristics and negotiation during the call or connection establishment phase for Broadband Integrated Services Digital Network (B-ISDN). Prepared by the Slovenski inštitut za standardizacijo (SIST) and harmonized with the European EN 301 067-3 standard, this document is crucial for ensuring conformance of equipment and implementations interacting at the user-network interface, particularly at the TB or coincident SB and TB reference points.

Key objectives:

• Outline the framework for structured TSS&TP for user entities conforming to the DSS2 protocol standards.
• Enhance testability and interoperability of B-ISDN equipment during call/connection establishment procedures.
• Define consistent naming conventions, test cases, and compliance requirements for protocol implementations.

Key Topics

• Test Suite Structure (TSS):

  • Defines structured groups of tests for negotiating connection parameters at both origination and destination interfaces.
  • Aligns signalling procedures with reference points (TB and coincident SB/TB) as outlined in ITU-T and EN standards.

• Test Purposes (TP):

  • Each test requirement corresponds to a clear TP, structured and numbered for traceability.
  • Emphasis is on externally observable behaviors of implementations under test (IUT), ensuring practical and relevant conformance testing.

• Negotiation Procedures:

  • Specifies protocol behaviors for traffic parameter negotiation and confirmation during the call setup phase.
  • Identifies correct reactions to valid and invalid parameter scenarios and required message exchanges.

• Compliance and Testing Service:

  • Details criteria for constructing compliant Abstract Test Suites (ATS) based on the TSS&TP.
  • Encourages the usage of remote test methods to ensure comprehensive conformance testing services.

Applications

Implementation of SIST EN 301 067-3 V1.1.3:2003 delivers significant benefits to organizations developing, testing, or deploying B-ISDN user equipment and services:

• Conformance Testing: Ensures that a user protocol implementation adheres to relevant DSS2 and B-ISDN standards, reducing deployment issues related to interoperability.
• Quality Assurance: Provides a reliable method for validating the robustness of signaling and negotiation during the connection establishment phase.
• Interoperability: Facilitates seamless communication between various manufacturers' equipment by standardizing the expected behaviors and message exchanges.
• Certification and Regulatory Compliance: Supports manufacturers and service providers in achieving compliance with European and international telecommunications standards.
• Product Development: Acts as a guideline for test-driven development and integration in systems supporting B-ISDN connections.

Related Standards

Several foundational standards are referenced or closely related to SIST EN 301 067-3 V1.1.3:2003:

• EN 301 067-1: B-ISDN DSS2 protocol specification for connection characteristics during establishment phase.
• EN 301 067-2: Protocol Implementation Conformance Statement (PICS) proforma specification.
• EN 300 443-1: Layer 3 specification for B-ISDN user-network interface.
• ISO/IEC 9646-1, -2: Open Systems Interconnection testing methodologies and frameworks.
• ETS 300 406: MTS - Protocol and profile conformance testing specifications.
• ITU-T Recommendation I.413: B-ISDN user-network interface.
• ITU-T Recommendation Q.2963.1: DSS2 connection modification procedures.

These standards collectively establish a benchmark for B-ISDN protocol conformance, interoperability, and best practices in protocol testing.
