SIST EN 301 068-3 V1.1.2:2003 is the Slovenian version of ETSI EN 301 068-3, a European Telecommunications Standard for Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2). It specifies the Test Suite Structure and Test Purposes (TSS&TP) for the user side at the TB or coincident SB/TB reference point, so testers can assess user implementations of ATM transfer capability and traffic parameter indication defined in EN 301 068-1.

What does SIST EN 301 068-3 V1.1.2:2003 specify?

SIST EN 301 068-3 V1.1.2:2003 specifies the user TSS&TP for implementations conforming to EN 301 068-1 at the TB reference point or the coincident SB/TB reference point. It is part 3 of a six-part EN series, and the series structure tells readers where this document fits in relation to the protocol, PICS, ATS and network-side testing parts.

Part	What it covers
Part 1	Protocol specification
Part 2	Protocol Implementation Conformance Statement (PICS) proforma
Part 3	Test Suite Structure and Test Purposes (TSS&TP) specification for the user
Part 4	Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the user
Part 5	TSS&TP specification for the network
Part 6	ATS and partial PIXIT proforma for the network

The document is organized into Scope, References, Definitions and abbreviations, Test Suite Structure, Test Purposes, Compliance, and Requirements for a comprehensive testing service. In practice, that structure makes it clear that this is a conformance-testing document, not a protocol implementation guide.

What are the key requirements of SIST EN 301 068-3 V1.1.2:2003?

The main requirement in SIST EN 301 068-3 V1.1.2:2003 is that conformance testing for the user side shall follow the TSS and TP structure defined in clause 4 and clause 5. The test purposes are organized so that a tester can select cases based on the implementation profile and then verify only observable signalling behaviour.

• Clause 4 defines the TSS around signalling procedures at the coincident SB/TB and TB reference points. In practice, this means the test suite is organized by interface position and by call/connection direction.
• Clause 5.1 gives a naming convention for TPs. The naming scheme lets labs trace each test purpose back to its group and test number, which is useful when selecting cases from a PICS proforma.
• Clause 5.1.3 states that the TPs are derived from EN 301 068-1 and from analysis of the base standard and the PICS specification. In practice, the tests focus on externally observable behaviour rather than internal design.
• Clause 5.1.4 ties many TPs to a final call state and uses the STATUS ENQUIRY and STATUS exchange to verify it. This matters because the final call state must be checked even when it is not repeated in every test step.
• Clause 5.1.5 limits validity to IUTs that do not use the negotiation procedure defined in EN 301 067-1. That tells users when this test suite applies and when another test specification is needed.
• Clause 5.2 divides the work into originating-interface and destination-interface procedures, covering the Sustainable Cell Rate parameter set, traffic management for tagging, Broadband Bearer Capability, Available Bit Rate (ABR), ATM Block Transfer (ABT), and error handling. These are the signalling cases that implementers need to verify.
• The error-handling TPs check malformed or unsupported combinations and the resulting call clearing behaviour. In practice, this means a device must reject invalid ATM traffic descriptors or unsupported parameter combinations in a predictable way.

What terms does SIST EN 301 068-3 V1.1.2:2003 define?

• Implementation Under Test (IUT) - The user-side implementation being exercised by the conformance tests.
• Test Purpose (TP) - A single stated objective for one test case or test case group.
• Test Suite Structure (TSS) - The way the test purposes are grouped and ordered for testing.
• Abstract Test Suite (ATS) - The set of abstract test cases built from the TSS&TP specification.
• Protocol Implementation Conformance Statement (PICS) - The proforma used to describe which protocol options an implementation supports.
• Protocol Implementation eXtra Information for Testing (PIXIT) - Extra implementation information needed to turn abstract tests into executable tests.
• User (TB) / user (SB/TB) - The DSS2 protocol entity at the user side of the user-network interface at the stated reference point.

Who uses SIST EN 301 068-3 V1.1.2:2003?

SIST EN 301 068-3 V1.1.2:2003 is used by conformance test laboratories, protocol implementers, and quality teams working on B-ISDN DSS2 user equipment. It helps them build or review an ATS, select cases from a PICS, and supply the PIXIT details needed for testing.

It is also relevant to organizations that provide a comprehensive testing service for network equipment claiming conformance to EN 301 068-1. For that use, clause 7 points to the Remote test method in ISO/IEC 9646-2.

Which standards are used with SIST EN 301 068-3 V1.1.2:2003?

• EN 301 068-1 - The base protocol specification whose user-side behaviour is being tested.
• EN 301 068-2 - The PICS proforma used to select relevant test cases.
• EN 300 443-1 - Provides the B-ISDN user-network interface layer 3 call/bearer control context and the call-state procedures used in the tests.
• EN 301 067-1 - Defines negotiation during call/connection establishment; clause 5.1.5 says the TP set applies only when that negotiation procedure is not used.
• ISO/IEC 9646-1 - Gives the conformance testing concepts used for TP, ATS, IUT, PICS and PIXIT.
• ISO/IEC 9646-2 - Gives the ATS specification framework and the Remote test method referenced for compliance and testing services.
• ITU-T Recommendation I.413 - Defines the B-ISDN user-network interface reference points used in the scope.
• ETS 300 406 - Provides the testing and specification methodology used for generating TPs.
• ITU-T Recommendations Q.2961, Q.2961.1, Q.2961.2, Q.2961.3 and Q.2961.4 - Provide the additional traffic-parameter signalling capabilities that the TP groups cover.

What does the SIST EN 301 068-3 V1.1.2:2003 document contain?

SIST EN 301 068-3 V1.1.2:2003 contains a figure showing the Test Suite Structure, a table defining the TP naming convention, and a detailed list of test purposes grouped into originating-interface and destination-interface cases. The TP list covers signalling for SETUP, CONNECT, CONNECT ACKNOWLEDGE, CALL PROCEEDING, ALERTING, RELEASE COMPLETE, and STATUS behaviour, together with the ATM traffic descriptor and related information elements.

Clause 6 states the conditions for a compliant ATS, and clause 7 states the minimum remote test method for a comprehensive testing service. The bibliography points to ISO/IEC 9646-3 for TTCN support material, and the history records the publication trail for version 1.1.2.
