Overview
SIST EN 301 068-3 V1.1.2:2003 is a Slovenian standard adopted from the European standard EN 301 068-3, developed by the European Telecommunications Standards Institute (ETSI) and maintained by the Slovenski inštitut za standardizacijo (SIST). The standard specifies the Test Suite Structure and Test Purposes (TSS&TP) specification for the user in the context of the Broadband Integrated Services Digital Network (B-ISDN) and the Digital Subscriber Signalling System No. two (DSS2) protocol. This part focuses on connection characteristics, including ATM transfer capability and traffic parameter indication at the user side of the user-network interface.
Conformance to this standard ensures that implementations of ATM and DSS2 protocols in B-ISDN environments are thoroughly tested for interoperability, security, and performance according to unified European requirements.
Key Topics
- Test Suite Structure (TSS): Outlines how conformance tests are organized for DSS2 implementations at the user side. It categorizes test cases by signalling procedures and ATM traffic parameter handling.
- Test Purposes (TP): Defines the objectives of each test case, supporting validation of connection setup, ATM transfer capabilities, traffic parameter negotiation, and correct error handling.
- ATM Transfer Capabilities: Includes sustainable cell rate, traffic management options (e.g., tagging), broadband bearer capability, available bit rate parameters, and ATM block transfer.
- Traffic Parameter Indication: Ensures the correct signalling and negotiation for traffic parameters such as sustainable cell rate and bit rates in various call states.
- Error Handling: Specifies test scenarios for dealing with invalid or unsupported parameter combinations, missing mandatory fields, and other protocol errors at the interface.
- Test Naming and Compliance: Prescribes conventions for test identification and compliance requirements for test suites (ATS), ensuring consistency and traceability.
Applications
This standard is crucial for:
- Network Equipment Manufacturers: Ensuring that ATM- and DSS2-capable devices are tested for compliance before deployment in B-ISDN environments.
- Test and Certification Bodies: Providing a reference for developing automated test suites and test tools aligned with European ISDN and ATM requirements.
- Network Operators and Service Providers: Validating conformance and interoperability of user-side equipment, promoting seamless integration and minimizing operational issues.
- System Integrators: Assisting in integration projects where compatibility between user equipment and B-ISDN network services is essential.
- Quality Assurance Teams: Supporting rigorous verification of protocol implementations to reduce errors and improve network reliability.
Typical scenarios include:
- Verifying the ability of user equipment to negotiate and establish ATM connections using DSS2 protocols.
- Testing correct behaviour under normal and abnormal conditions, such as incorrect parameter combinations or incomplete messages.
- Ensuring support for various ATM transfer capabilities and traffic management options relevant to high-speed broadband networks.
Related Standards
For comprehensive implementation and testing in B-ISDN environments, the following standards are closely related:
- EN 301 068-1: Protocol specification for DSS2, ATM transfer capability, and traffic parameter indication.
- EN 301 068-2: Protocol Implementation Conformance Statement (PICS) proforma.
- EN 301 068-4: Abstract Test Suite and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the user.
- EN 301 068-5 & EN 301 068-6: Test Suite Structure and ATS/PIXIT specifications for the network side.
- ISO/IEC 9646 series: General concepts and frameworks for conformance testing methodologies.
- ITU-T Recommendations Q.2961.x: Additional signalling capabilities for ATM traffic parameters.
- EN 300 443-1: Specification for DSS2 user-network interface layer 3.
By adhering to SIST EN 301 068-3 and related standards, stakeholders ensure proper conformance assessment of DSS2 and ATM protocol implementations, leading to robust, interoperable broadband ISDN solutions.
