SIST EN 301 003-6 V1.2.1:2004 is the Slovenian adoption of ETSI EN 301 003-6 V1.2.1 for Broadband Integrated Services Digital Network (B-ISDN) and the Digital Subscriber Signalling System No. two (DSS2) protocol. It specifies the network Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for peak cell rate modification by the connection owner. It is meant for conformance testing of the network side at the TB reference point or the coincident SB and TB reference point.

What does SIST EN 301 003-6 V1.2.1:2004 specify?

SIST EN 301 003-6 V1.2.1:2004 specifies how to test network implementations of EN 301 003-1 for the DSS2 peak cell rate modification by the connection owner service. The document focuses on the network Implementation Under Test (IUT) at the user-network interface, not on the whole network.

The document is organized into clauses for scope, references, definitions, the Abstract Test Method (ATM), untestable test purposes, ATS-to-TP mapping, and conformance rules, followed by three normative annexes.

Annex	What it covers
Annex A	Protocol Conformance Test Report (PCTR) proforma
Annex B	Partial PIXIT proforma
Annex C	Abstract Test Suite (ATS)

This structure matters in practice because the ATS defines the tests, the PIXIT collects the implementation-specific information needed to run them, and the PCTR provides the report format used to record results.

What are the key requirements of SIST EN 301 003-6 V1.2.1:2004?

Clause 4 says the network ATS uses a multi-party test method combined with remote testing. In practice, this means one Main Test Component (MTC) controls the test and one or more Parallel Test Components (PTCs) stimulate other interfaces while verdicts are taken only from the interface under test.

Clause 4 also explains the role of the Point of Control and Observation (PCO). The MTC uses the lower PCO, called L0, to control and observe the IUT, while the PTCs use other PCOs to drive supporting behavior at related interfaces.

Clause 4 makes a practical limitation clear: if the network fails to react at the tested interface after stimulus at another interface, the result is reported as INCONCLUSIVE rather than FAIL. That matters because it separates a protocol failure at the interface under test from a possible coordination issue elsewhere in the network.

Clause 5 states that there are no untestable test purposes associated with this ATS. That means the defined test purposes are intended to be covered by the suite.

Clause 6 defines a one-to-one mapping between the test purpose identifiers in EN 301 003-5 and the ATS test case names. This helps users trace each test case back to its test purpose without ambiguity.

Clauses 7, 8 and 9 define conformance for reports, PIXIT material and the ATS itself. A test laboratory producing a PCTR must use the Annex A proforma, a test realizer must produce an augmented partial PIXIT compatible with Annex B, and an executable test suite must be technically equivalent to the ATS in Annex C.

What terms does SIST EN 301 003-6 V1.2.1:2004 define?

• Abstract Test Method (ATM) - The testing approach used to structure the ATS, here based on a multi-party method with remote and local control points.
• Abstract Test Suite (ATS) - The set of abstract test cases that define the conformance checks.
• Implementation Under Test (IUT) - The network implementation being assessed for conformance.
• Main Test Component (MTC) - The test component that controls the test execution and assigns verdicts at the main observation point.
• Parallel Test Component (PTC) - A supporting test component used to stimulate or observe other interfaces during a test.
• Protocol Implementation eXtra Information for Testing (PIXIT) - Implementation-specific information needed to prepare and run the tests.
• Point of Control and Observation (PCO) - The interface where the tester controls the IUT and observes its behavior.
• TB reference point - The user-network interface reference point targeted by the ATS for this document.

Who uses SIST EN 301 003-6 V1.2.1:2004?

Test laboratories use this standard to prepare and run conformance tests and to produce the PCTR. Test realizers use it to build an executable test suite and the related PIXIT material. Equipment vendors and implementers of B-ISDN DSS2 network functionality use it when preparing their implementations and test information for the network side. Clients of test laboratories use the PIXIT and PCTR forms to define the test setup and record results.

Which standards are used with SIST EN 301 003-6 V1.2.1:2004?

Standard	What it contributes
EN 301 003-1	The protocol specification being tested
EN 301 003-2	The PICS proforma for the same service
EN 301 003-5	The network Test Suite Structure and Test Purposes referenced by the ATS
EN 300 443-1	A related B-ISDN DSS2 layer 3 protocol specification
EN 300 443-2	The related PICS proforma referenced for completion of the PICS
ISO/IEC 9646-1 to 9646-5	The conformance testing framework, ATS specification, TTCN, test realization, and test laboratory requirements
ITU-T Recommendation I.413	The B-ISDN user-network interface reference points
ITU-T Recommendation Q.2963.1	The underlying DSS2 connection modification specification

What does the SIST EN 301 003-6 V1.2.1:2004 document contain?

Annex A gives a structured PCTR form with sections for identification, IUT identification, test environment, static and dynamic conformance summaries, and a test campaign report. Annex B provides the partial PIXIT form with fields for the test laboratory, client, SUT, protocol information, configuration to be tested, timer values, and parameter values needed for call establishment and modification tests.

Annex C contains the ATS itself in Tree and Tabular Combined Notation (TTCN), in both TTCN.GR and TTCN.MP forms. The document also includes figures that explain the multi-party test method and the relationship between the tester components and the network interfaces. In practice, these annexes support test preparation, test execution, and formal reporting rather than giving marketing or product guidance.
