SIST EN 301 068-6 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 068-6, a telecommunications conformance-testing standard for B-ISDN. It specifies the network Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the DSS2 protocol connection characteristics for ATM transfer capability and traffic parameter indication. The focus is the network side at the TB reference point or coincident SB and TB reference point.
What does SIST EN 301 068-6 V1.1.1:2003 specify?
SIST EN 301 068-6 V1.1.1:2003 specifies the network ATS for implementations conforming to EN 301 068-1 at the TB reference point or coincident SB and TB reference point. It is part 6 of EN 301 068, and the foreword says the related parts cover the protocol specification, PICS, and user-side test material.
The document is organized into clauses on scope, references, definitions, the abstract test method, untestable test purposes, ATS-to-TP mapping, and conformance for PCTR, PIXIT, and ATS. Annexes A to C carry the reusable reporting and test-suite material.
| Annex | What it covers |
|---|---|
| A | Protocol Conformance Test Report (PCTR) proforma |
| B | Partial PIXIT proforma |
| C | Abstract Test Suite (ATS) in TTCN.GR and TTCN.MP forms |
What are the key requirements of SIST EN 301 068-6 V1.1.1:2003?
SIST EN 301 068-6 V1.1.1:2003 is built around a multi-party abstract test method and standardized reporting so that test results are traceable and comparable.
Test method and verdicts
- Clause 4.1 uses a combination of remote and multi-party test methods, with one Main Test Component (MTC) and one or more Parallel Test Components (PTCs). In practice, this lets the test system stimulate other interfaces while focusing verdicts on the interface under test.
- Clause 4.2 says the MTC controls the PTCs and that verdicts are assigned from the behaviour observed at the lower PCO, called L0. Messages seen only on supporting interfaces do not themselves produce verdicts, so the lab must judge the tested interface, not the helper interfaces.
- Clause 4.2 also states that if a network-generated message is not received at L0 after a trigger on another interface, the result is INCONCLUSIVE rather than FAIL. This matters because it separates a true protocol failure from a dependency on other interfaces.
Test purposes and traceability
- Clause 5 states that there are no untestable test purposes associated with this ATS. For the reader, that means every test purpose in the suite is intended to be exercised.
- Clause 6 maps test purpose identifiers directly to test case names on a one-to-one basis. That makes it easier to match a report, a test case, and the underlying purpose.
Reporting, PIXIT, and ATS conformance
- Clause 7 and Annex A require a PCTR that follows the annex A proforma. The report keeps a fixed structure with identification, conformance status, static and dynamic summaries, test campaign results, and observations.
- Clause 8 and Annex B require a partial PIXIT proforma, technically equivalent to annex B and optionally augmented with extra questions for a particular implementation or test lab. Annex B collects the data needed to prepare the Means of Testing, including configuration, timers, and protocol parameter values.
- Clause 9 and Annex C require any Means of Testing and Executable Test Suite to comply with ISO/IEC 9646-4, and the ExTS must be technically equivalent to the ATS in annex C. Extra checks outside the ATS do not count in verdict assignment.
What terms does SIST EN 301 068-6 V1.1.1:2003 define?
- Abstract Test Suite (ATS) - the set of abstract test cases used to verify conformance, written here using TTCN.
- Protocol Implementation eXtra Information for Testing (PIXIT) - implementation-specific information needed to prepare and run the tests.
- Implementation Under Test (IUT) - the network DSS2 protocol entity being assessed.
- System Under Test (SUT) - the specific system configuration that contains the IUT.
- Main Test Component (MTC) - the controlling test component that coordinates the test execution.
- Parallel Test Component (PTC) - an additional test component used to drive or observe other interfaces.
- Point of Control and Observation (PCO) - the interface where the tester controls and observes protocol behaviour.
Who uses SIST EN 301 068-6 V1.1.1:2003?
SIST EN 301 068-6 V1.1.1:2003 is used by test laboratories, test realizers, and equipment vendors or network implementers who need to check the network side of DSS2 against EN 301 068-1. It is also used by clients who commission conformance testing, because it defines the PIXIT information they must provide and the PCTR format they receive back.
Which standards are used with SIST EN 301 068-6 V1.1.1:2003?
- EN 301 068-1 - the protocol specification being tested.
- EN 301 068-2 - the PICS proforma for the same protocol.
- EN 300 443-1 - the related DSS2 layer 3 specification for basic call/bearer control, used for additional definitions.
- EN 300 443-2 - the related PICS proforma for that basic call/bearer control part.
- ISO/IEC 9646-1 - general conformance testing concepts and framework.
- ISO/IEC 9646-2 - ATS specification and abstract test methods.
- ISO/IEC 9646-3 - TTCN notation.
- ISO/IEC 9646-4 - test realization and ExTS requirements.
- ISO/IEC 9646-5 - test laboratory and client requirements, including PCTR.
- ITU-T Recommendation I.413 - the B-ISDN user-network interface reference points.
The foreword also names the companion EN 301 068 parts: part 3 and part 5 cover test purposes for the user and network, while part 4 and part 6 cover the ATS and PIXIT proformas for the user and network.
What does the SIST EN 301 068-6 V1.1.1:2003 document contain?
Annex A provides a structured PCTR form with fields for identification, test environment, conformance status, static and dynamic summaries, and observations. Annex B provides the partial PIXIT form, including test lab and client details, SUT information, configuration to be tested, test management timers such as T313, TAC, TNOAC and TWAIT, and protocol parameter values.
Annex C contains the ATS in TTCN.GR and TTCN.MP forms, and the document notes that both published forms are equivalent. The body also explains the multi-party test setup, the role of the MTC and PTCs, and how verdicts are assigned during conformance testing.
