SIST EN 300 394-4-4 V1.1.1:2003 is the SIST adoption of the ETSI European Standard for TETRA conformance testing, focused on Direct Mode Operation (DMO). It specifies the Test Suite Structure and Test Purposes (TSS&TP) for Direct Mode Repeater (DM-REP) type 1, so test laboratories and implementers can check protocol behavior on the DMO air interface. The document is aimed at approval testing of equipment that needs to interwork with other manufacturers' TETRA equipment.

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

SIST EN 300 394-4-4 V1.1.1:2003 specifies the TSS and Test Purposes for testing TETRA DMO protocols for DM-REP type 1. The focus is the air interface protocol at data link layer 2 only, and security features are outside its scope.

The standard is organized into clauses for scope, references, definitions and abbreviations, Test Suite Structure, introduction to Test Purposes, and DM-REP1 test purposes. The document also contains a bibliography and history.

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

SIST EN 300 394-4-4 V1.1.1:2003 sets out how to structure conformance tests and what behaviors to check for a DM-REP1 implementation. Its practical value is that it turns the DMO repeater behavior into named test purposes that can be selected from a PICS/PIXIT profile and executed in a TTCN-based conformance campaign.

Test suite structure and grouping

Clause 4 splits the MAC layer tests into four groups: capability (CA), valid behaviour (BV), invalid behaviour (BI), and timer tests (TI). In practice, this helps a test team cover supported functions, correct reactions, incorrect inputs, and timeout handling in a controlled way.

Test purpose definition and selection

Clause 5 defines each TP in a table with fields such as TP name, requirement reference, purpose, selection expression, test description, pass criteria, preamble, and postamble. The selection expressions use PICS statements, so only the cases relevant to the implementation under test are run.

Naming and test configuration

Clause 5 also defines the TP naming pattern as DMO////, where the test suite type is DMREP1 and the test type can be CA, BV, BI, or TI. Clause 6 defines the test setup: the IUT is a DM-REP1, the main tester is a MS connected to a type 1 repeater and acts as master, and a parallel tester acts as slave.

Capability checks

In the CA group, the standard checks basic functions such as fill bit addition and deletion and presence signal behavior. For users, this means verifying that the repeater forwards the right signaling and timing behavior when a supported service is used.

Valid behaviour checks

The BV group covers correct retransmission and protocol handling, including call setup with and without presence check, re-transmission of signaling, SDS fragmentation, and message forwarding. This matters because a repeater must pass on the right protocol data while preserving the expected call or service flow.

Invalid behaviour and timer handling

The BI group checks that the IUT ignores signaling when the repeater address is wrong. The TI group checks loss-of-call handling when timers expire, such as missing DM-OCCUPIED, missing DM-RESERVED, or missing DM-CONNECTACK. In practice, these tests confirm that the repeater returns to idle when the procedure fails.

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

• DMO (Direct Mode of Operation) - The TETRA mode covered here, where radios communicate directly rather than through the network.
• DM-REP1 - Direct Mode Repeater type 1, the implementation under test in this sub-part.
• MAC (Medium Access Control) - The layer whose test groups and test purposes are defined in this document.
• IUT (Implementation Under Test) - The DM-REP1 equipment being evaluated.
• PICS (Protocol Implementation Conformance Statement) - The statement used to decide which test cases apply to the implementation.
• PIXIT (Protocol Implementation eXtra Information for Testing) - Extra implementation information used when selecting and running tests.
• TSS (Test Suite Structure) - The way the conformance tests are grouped and organized.
• TP (Test Purpose) - The stated objective and expected outcome of a specific test case.

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

SIST EN 300 394-4-4 V1.1.1:2003 is used by conformance test laboratories, equipment manufacturers, approval test teams, and quality engineers working with TETRA DMO equipment. It supports protocol testing of mobile stations and repeater-related behavior where direct mode interoperability matters.

What changed in SIST EN 300 394-4-4 V1.1.1:2003 from the previous edition?

SIST EN 300 394-4-4 V1.1.1:2003 was converted from an ETS into an EN during the approval process. The history records the edition as Version 1.1.1 and shows publication after public enquiry and vote.

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

SIST EN 300 394-4-4 V1.1.1:2003 references these standards and companion parts:

• EN 300 396-4 - Provides the DMO technical requirements for the Type 1 repeater Air Interface, which the test purposes reference.
• EN 300 396-8-2 - Provides the PICS proforma used for test selection.
• ISO/IEC 9646-1 - Gives the general conformance testing methodology and framework.
• ISO/IEC 9646-2 - Gives the Abstract Test Suite specification methodology.
• ETS 300 406 - Provides ETSI testing and specification methodology.
• ETS 300 396-1 - Listed in the bibliography as supporting information for DMO general network design.

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

SIST EN 300 394-4-4 V1.1.1:2003 contains a MAC-layer test suite structure and a set of test purposes for DM-REP1. It describes how to name, select, and execute cases, and it links each TP to the relevant EN 300 396-4 requirement.

The document includes capability tests, valid behaviour tests, invalid behaviour tests, and timer tests. It also gives the test configuration with main and parallel testers, which is what a lab needs to set up observed retransmission and address-handling cases.

Clause 6 lists individual DM-REP1 test purposes such as fill bit handling, presence signal sending, retransmission of setup and connect messages, SDS fragmentation, and timer expiry behavior. These cases are the practical core of the standard for conformance and approval testing.
