SIST EN 300 394-4-12 V1.1.1:2003 is the Slovenian adoption of the ETSI European Standard for Terrestrial Trunked Radio (TETRA) conformance testing. It specifies the Test Suite Structure (TSS) and Test Purposes (TPs) for protocol testing of Direct Mode Operation (DMO) Repeater type 2, so test labs and implementers can check whether equipment behaves as required on the air interface.

What does SIST EN 300 394-4-12 V1.1.1:2003 specify?

SIST EN 300 394-4-12 V1.1.1:2003 specifies the DMO protocol test framework for the DM-REP2 case, with a focus on the MAC layer and layer 2 behavior. It is part 4 of the TETRA conformance testing specification, and sub-part 12 covers only the Direct Mode Repeater type 2 air interface.

The scope ties the document to protocol conformance testing for DMO and excludes security feature testing. In practice, that means the document is used to check communication behavior, retransmission, addressing and timer-related behavior, not security functions.

The document is organized into:

• Clause 1 - scope
• Clause 2 - references
• Clause 3 - definitions and abbreviations
• Clause 4 - Test Suite Structure
• Clause 5 - introduction to Test Purposes
• Clause 6 - DM-REP2 test purposes
• Bibliography and history

What are the key requirements of SIST EN 300 394-4-12 V1.1.1:2003?

Test method and structure

SIST EN 300 394-4-12 V1.1.1:2003 uses ISO/IEC 9646-1, ISO/IEC 9646-2 and ETSI ETS 300 406 as the basis for the conformance testing methodology. In practice, this anchors the tests in a formal TTCN-style approach, so laboratories can build repeatable approval tests.

Clause 4 divides the MAC tests into four groups: capability tests, valid behaviour tests, invalid behaviour tests and timer tests. This helps a tester choose the right kind of case: capability checks for what the implementation claims, valid behaviour checks for expected protocol responses, invalid behaviour checks for incorrect input, and timer checks for expiry handling.

How each test purpose is defined

Clause 5 defines each TP by a fixed set of information: TP name, requirement reference, purpose, selection expression, test description, pass criteria, preamble and postamble. That structure matters because it tells the tester what requirement is being exercised, how the case is selected from the implementation profile, and what observable result counts as a pass.

The naming convention in clause 5 identifies the test suite type, the test type and a sequential number. In practice, this makes each case traceable in reports and PICS/PIXIT-based selection.

What the DM-REP2 cases check

Clause 6 sets the test configuration for DM-REP2: the implementation under test is a DM-REP2, the main tester acts as a mobile station, and a parallel tester plays the other side of the repeater link. Most cases verify that the repeater retransmits received information correctly between the two testers.

The DM-REP2 MAC test cases cover:

• capability behavior such as fill-bit handling and presence signalling
• valid signalling retransmission, including setup, connect, disconnect and SDS data
• invalid cases such as wrong repeater address handling
• timer-related loss-of-call behavior when expected responses do not arrive

For a buyer or engineer, this means the document is mainly a checklist of observable DMO repeater behavior, especially retransmission and timing under normal and faulty conditions.

What terms does SIST EN 300 394-4-12 V1.1.1:2003 define?

• Implementation Under Test (IUT) - the equipment being tested in the conformance setup.
• Protocol Implementation Conformance Statement (PICS) - the statement of supported protocol features used to select applicable tests.
• Protocol Implementation eXtra Information for Testing (PIXIT) - extra implementation details needed to run or select tests correctly.
• Test Purpose (TP) - a single stated objective for one test case.
• Test Suite Structure (TSS) - the way the whole set of tests is grouped and organized.
• Direct Mode Operation (DMO) - TETRA operation without network infrastructure, using direct radio links.
• Mobile Station (MS) - the radio terminal role used in the test configuration.
• Terrestrial Trunked Radio (TETRA) - the digital trunked radio system covered by the standard.

Who uses SIST EN 300 394-4-12 V1.1.1:2003?

SIST EN 300 394-4-12 V1.1.1:2003 is used by TETRA equipment manufacturers, conformance test laboratories, approval bodies and technical evaluators. They use it to prepare test cases, assess a repeater implementation against the DMO MAC requirements, and document whether claimed features match observed behavior. Quality and procurement teams can use it to understand what kind of interoperability evidence a supplier can provide.

Which standards are used with SIST EN 300 394-4-12 V1.1.1:2003?

Clause 2 names the main companion documents:

• EN 300 396-7 - gives the DMO type 2 repeater air interface requirements that the tests reference.
• EN 300 396-8-4 - provides the PICS proforma used in test selection for type 2 repeater air interface cases.
• EN 300 396-8-2 - appears in selection expressions for some cases involving related DMO capabilities.
• ISO/IEC 9646-1 - gives the general conformance testing concepts.
• ISO/IEC 9646-2 - defines the abstract test suite specification method.
• ETS 300 406 - gives ETSI methodology for protocol and profile conformance test specifications.

What does the SIST EN 300 394-4-12 V1.1.1:2003 document contain?

The document contains the TSS and TP framework for DM-REP2, plus the test-group descriptions and the detailed TP descriptions in clause 6. Those TP descriptions give the requirement references, the test objective, the selection logic, the setup, and the pass criteria for each case. It also includes the conventions for naming and selecting test cases from the implementation profile.

For practical use, the document is a guide for building and running protocol conformance tests, not a product design specification. It tells the tester how to structure the campaign and what behavior to observe on retransmission, address handling, presence signalling, fragmentation and timer expiry.
