SIST EN 300 347-4 V3.1.1:2005 is the Slovenian adoption of the ETSI standard for the V5.2 interface between a digital Local Exchange (LE) and an Access Network (AN). It specifies the Abstract Test Suite (ATS) and a partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the network layer on the AN side, so test laboratories and implementers can assess conformance and prepare interoperability tests.
What does SIST EN 300 347-4 V3.1.1:2005 specify?
SIST EN 300 347-4 V3.1.1:2005 defines how to test the V5.2 network layer used by the AN side of the interface, and it also includes the information needed to adapt those tests to a specific implementation. The document’s stated objective is to provide conformance tests with a high probability of interoperability between AN and LE equipment from different manufacturers.
The document is organized into:
- scope, references, definitions and abbreviations
- the abstract test method
- untestable test purposes
- ATS conventions
- Annex A with the ATS
- Annex B with the partial PIXIT proforma
| Annex | What it covers |
|---|---|
| Annex A | Abstract Test Suite for NWK testing, in TTCN.GR and TTCN.MP forms |
| Annex B | Partial PIXIT proforma, including identification, test lab, SUT, protocol, parameters, timers, procedures and optional information |
What are the key requirements of SIST EN 300 347-4 V3.1.1:2005?
SIST EN 300 347-4 V3.1.1:2005 is built around a remote test method for network layer conformance testing. Clause 4 says this is the principal method, and that an embedded variant is also used where test purposes need service and national functions. In practice, the PIXIT supplies the national-dependent details the test system cannot assume.
Clause 4 also fixes the points of control and observation (PCO). For NWK testing, events at the DSAP are expressed as Data Link Layer (DLL) Abstract Service Primitives and network layer Protocol Data Units (PDUs), while PSAP events use physical layer ASPs and PSTN_ACCESS and PCM_ACCESS use ASPs. This matters because the tester must inject and observe the right event type at the right interface.
The document assigns V5DLaddr values to the network layer protocol functional entities. Clause 4 explains that each entity has one datalink connection, so the test configuration must match the correct address to the correct protocol function.
Clause 4 also prescribes a test execution order. The startup test case is always first, and when the IUT is restarted that test case is also first. The protocol group order is CTRL, LINK, PROTECTION, PSTN, BCC, and the test group order is ITC, ATI, BV, BO, BI. This helps avoid interference between cases and keeps restart-dependent tests reproducible.
Clause 5 lists untestable test purposes for Control, PSTN, Link control, BCC and Protection protocols. These are test purposes not implemented in the ATS because of the abstract test method, unknown IUT reactions, or overlap with already implemented cases. For a reader, that means the ATS is not a complete replacement for all test purposes in the companion TSS & TP specification.
Clause 6 defines the ATS conventions for TTCN. It gives naming rules for declarations, constraints, test cases, test steps, verdict labels and ATS abbreviations. These rules matter because they make the suite readable, maintainable and traceable in execution logs.
Clause 6 also describes implementation practice for the ATS. It explains how comments reference the protocol specifications, how optional information elements are handled through PIXIT, how preambles and postambles are structured, and how verdicts are assigned in defaults. It also notes that some test cases use implicit send events and manual operations.
What terms does SIST EN 300 347-4 V3.1.1:2005 define?
- ATS (Abstract Test Suite) - The TTCN test cases and related structures used to verify conformance.
- ATM (Abstract Test Method) - The test approach that defines how control and observation are arranged.
- PIXIT (Protocol Implementation eXtra Information for Testing) - Implementation-specific data needed to run the tests correctly.
- NWK (Network layer) - The protocol layer tested by this part on the AN side.
- PCO (Point of Control and Observation) - The interface point where the test system controls and observes the IUT.
- SUT (System Under Test) - The complete implementation and environment being tested.
- IUT (Implementation Under Test) - The specific implementation whose conformance is being checked.
- TTCN (Tree and Tabular Combined Notation) - The notation used to write the ATS.
Who uses SIST EN 300 347-4 V3.1.1:2005?
SIST EN 300 347-4 V3.1.1:2005 is used by conformance test laboratories, telecommunications equipment manufacturers, and integrators working on V5.2 AN and LE equipment. It is also relevant to quality and interoperability teams that need to prepare PIXIT data, select applicable tests, and document the test environment. In practice, it supports testing, acceptance, and interoperability work for switching and signalling systems.
What changed in SIST EN 300 347-4 V3.1.1:2005 from the previous edition?
SIST EN 300 347-4 V3.1.1:2005 updates the test specifications so they are aligned with the 3rd edition of the base protocol standard.
Which standards are used with SIST EN 300 347-4 V3.1.1:2005?
- EN 300 347-1 - The V5.2 interface specification that provides the base protocol behavior and data used by the tests.
- EN 300 347-2 - The PICS proforma, used to identify the implementation features that affect test selection.
- EN 300 347-3 - The TSS & TP specification for the network layer on the AN side, which the ATS implements.
- ETS 300 324-1, ETS 300 324-3, ETS 300 324-4 - Earlier V5.1 and ATS-related documents used for related protocol definitions, test purposes and terminology.
- ISO/IEC 9646-1, -2, -3, -5 - The conformance testing framework, ATS specification, TTCN notation, and laboratory/client requirements.
- ETS 300 406 and ETR 141 - ETSI testing methodology and TTCN style guidance used when defining the ATS.
- EN 300 377-1 - The Q3 interface specification used where system management functions depend on configuration management.
What does the SIST EN 300 347-4 V3.1.1:2005 document contain?
SIST EN 300 347-4 V3.1.1:2005 contains the abstract test method, the naming and implementation conventions for the ATS, and the list of untestable test purposes by protocol area. Annex A provides the full ATS in both TTCN.GR and TTCN.MP forms, while Annex B gives the partial PIXIT proforma for lab, client, SUT, protocol, address, timer, parameter and implicit-event information. The PIXIT tables are what a test lab uses to capture the site-specific data needed before execution.
