SIST EN 301 067-4 V2.1.1:2003 is the Slovenian adoption of the ETSI standard for B-ISDN DSS2 user-side conformance testing. It specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for negotiation during call/connection establishment at the TB reference point or coincident SB/TB reference point. The document is intended for implementers, test laboratories, and clients who need to assess conformance against EN 301 067-1.

What does SIST EN 301 067-4 V2.1.1:2003 specify?

SIST EN 301 067-4 V2.1.1:2003 specifies the user ATS for implementations of the DSS2 protocol connection-characteristics negotiation function on the B-ISDN user side. It also gives the related Test Suite Structure and Test Purposes (TSS&TP) link, plus a partial PIXIT proforma for preparing tests.

The scope covers the TB reference point, or the coincident SB and TB reference point, as defined in ITU-T I.413. It also points to the network-side parts of the same EN, which are covered separately.

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

The main body is organized into scope, references, definitions and abbreviations, the abstract test method, untestable test purposes, ATS-to-TP mapping, and conformance statements.

What are the key requirements of SIST EN 301 067-4 V2.1.1:2003?

Test method

SIST EN 301 067-4 V2.1.1:2003 uses a remote test method for the user ATS. The Point of Control and Observation (PCO) is the L0 point at the service access point between layers 2 and 3, so test verdicts are based on behavior seen there.

The ATS also uses an informal O PCO above the IUT for control actions only. In practice, that means the tester can be told what to do to drive the IUT, but events at O are not used to decide pass or fail.

Test purpose and mapping

SIST EN 301 067-4 V2.1.1:2003 states that there are no untestable test purposes for this ATS. It also reuses the TP identifiers from EN 301 067-3 as test case names, giving a one-to-one mapping.

This is useful because a reader can move directly from a test purpose in Part 3 to the corresponding ATS test case in Part 4 without renaming or relabeling.

Conformance reporting and test preparation

SIST EN 301 067-4 V2.1.1:2003 requires a PCTR to follow the ISO/IEC 9646-5 template and the proforma in Annex A. The report keeps the Annex A clause order, and the laboratory may add columns in clause A.6 if needed.

For PIXIT handling, the test realizer and test laboratory must produce an augmented PIXIT that is technically equivalent to Annex B. This lets the laboratory collect the exact configuration, timer, stimulus, and parameter values needed for a particular IUT.

ATS conformance requires an MOT and ExTS that are technically equivalent to Annex C, and the test laboratory must comply with ISO/IEC 9646-5. In practice, that ties the executable test environment back to the published abstract tests.

What terms does SIST EN 301 067-4 V2.1.1:2003 define?

• Abstract Test Suite (ATS) - the formal set of abstract test cases used to assess conformance.
• Protocol Implementation eXtra Information for Testing (PIXIT) - extra implementation-specific information needed to set up testing.
• Protocol Conformance Test Report (PCTR) - the report format used to record conformance test results.
• Implementation Under Test (IUT) - the protocol implementation being assessed.
• System Under Test (SUT) - the full system or configuration exercised during testing.
• Point of Control and Observation (PCO) - the point where the tester controls and observes protocol behavior.

Who uses SIST EN 301 067-4 V2.1.1:2003?

SIST EN 301 067-4 V2.1.1:2003 is used by telecom equipment vendors, protocol implementers, and conformance test laboratories working on B-ISDN DSS2 user-side signaling. It is also used by clients commissioning tests and by test realizer teams that build executable test suites from the ATS.

What changed in SIST EN 301 067-4 V2.1.1:2003 from the previous edition?

SIST EN 301 067-4 V2.1.1:2003 aligns edition 1 with the TSS&TP in Part 3 and corrects other possible errors based on contributions. It also develops Part 4 as the ATS and partial PIXIT for the user.

Which standards are used with SIST EN 301 067-4 V2.1.1:2003?

• EN 301 067-1 - the protocol specification that defines the user signaling behavior being tested.
• EN 301 067-2 - the PICS proforma used for implementation declarations.
• EN 301 067-3 - the user-side TSS&TP source for the ATS test purposes.
• EN 300 443-1 / EN 300 443-2 - related B-ISDN DSS2 basic call/bearer control references used in the PIXIT note.
• ISO/IEC 9646-1 to 9646-5 - the conformance testing framework, ATS specification, TTCN, test realization, and laboratory requirements.
• ITU-T I.413 - the B-ISDN user-network interface reference used to define the TB and coincident SB/TB points.

What does the SIST EN 301 067-4 V2.1.1:2003 document contain?

Annex A provides a structured PCTR form with identification, environment, conformance summaries, and test campaign reporting fields. Annex B provides the PIXIT proforma with sections for the test laboratory, client, SUT, protocol information, timers, and parameter values.

Annex C contains the ATS in TTCN form. The document points to both the TTCN graphical form and the machine-processable form, which are the practical artifacts used to realize the tests in a test system.
