SIST EN 300 324-6 V3.1.1:2005 is the Slovenian adoption of ETSI EN 300 324-6, a conformance test specification for the V5.1 interface at the digital Local Exchange (LE). It defines an Abstract Test Suite (ATS), an Abstract Test Method (ATM), and a partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the network layer on the LE side of a V5.1 interface supporting an Access Network (AN). In practice, it is used to test whether AN and LE implementations can interwork over the V5.1 interface.
What does SIST EN 300 324-6 V3.1.1:2005 specify?
SIST EN 300 324-6 V3.1.1:2005 specifies the ATS and partial PIXIT proforma for the V5.1 network layer, plus parts of system management on the LE side. The document is organized around the test method, test-suite conventions, the normative ATS in Annex A, and the partial PIXIT proforma in Annex B.
| Annex | What it covers |
|---|---|
| Annex A | Abstract test suite for NWK testing, including TTCN.GR and TTCN.MP representations |
| Annex B | Partial PIXIT proforma with identification, addresses, timers, procedures, implicit event data, and PICS information |
The ATS is based on test purposes from EN 300 324-5 and is written in TTCN. That matters because the document is not a product specification - it is a test specification that tells a lab how to exercise implementations.
What are the key requirements of SIST EN 300 324-6 V3.1.1:2005?
SIST EN 300 324-6 V3.1.1:2005 uses the remote test method for V5.1 LE network-layer conformance testing, and it applies the embedded variant where test purposes depend on service and national functions. In practice, the PIXIT must capture the national-dependent information needed to run those cases.
Clause 4.2 places the point of control and observation at the data link service access point (DSAP). Test events at that point are expressed as data link Abstract Service Primitives (ASPs) and network layer Protocol Data Units (PDUs). This tells the test lab where to observe traffic and what form the exchanged events must take.
Clause 4.3 assigns V5 Data Link addresses (V5DLaddr) to the Control and PSTN protocol entities. Each network-layer protocol functional entity uses one data link connection, so the tester must map the correct address to the correct entity before execution.
Clause 4.4 requires the start-up test case to run first, and again after any restart of the implementation under test. That is important because later cases assume the system has been initialized in a known state.
Clause 5 lists test purposes that are not covered by the ATS because of the chosen test method or because the implementation reaction is not known after those tests. For a user of the standard, this means the ATS is not a complete catalog of every possible test purpose in the companion test-purpose document.
Clause 6 fixes the naming and implementation conventions for TTCN. It defines how declaration names, constraints, test cases, test steps, and verdict labels are written, and it requires labeled verdict assignments for traceable logs. The same clause also explains how optional information and implicit send events are handled through PIXIT data.
Clause 6.2 also states that base constraints carry the relevant parameters, while optional PSTN information is supplied through PIXIT entries. In practice, the tester must complete the PIXIT so the ATS can form the right messages and trigger the intended implicit events.
What terms does SIST EN 300 324-6 V3.1.1:2005 define?
- Abstract Test Suite (ATS) - a set of abstract test cases that implement the test purposes for conformance testing.
- Abstract Test Method (ATM) - the testing approach used to apply the ATS, here the remote test method and its embedded variant.
- Protocol Implementation eXtra Information for Testing (PIXIT) - implementation-specific information needed to execute the ATS correctly.
- Protocol Implementation Conformance Statement (PICS) - the implementer’s statement of which protocol options and features are supported.
- Point of Control and Observation (PCO) - the location where the tester controls and observes the implementation under test.
- Implementation Under Test (IUT) - the implementation being checked for conformance.
- System Under Test (SUT) - the whole system arrangement being exercised during testing.
Who uses SIST EN 300 324-6 V3.1.1:2005?
SIST EN 300 324-6 V3.1.1:2005 is used by conformance test laboratories, network equipment manufacturers, and engineering teams responsible for LE and AN implementations. Buyers and quality managers use it to understand what evidence a supplier can produce for V5.1 network-layer testing. Test engineers use it to prepare TTCN-based executions, complete the PIXIT, and interpret verdicts and logs.
What changed in SIST EN 300 324-6 V3.1.1:2005 from the previous edition?
SIST EN 300 324-6 V3.1.1:2005 updates the test specifications so they are in line with the 3rd edition of the base protocol standard.
Which standards are used with SIST EN 300 324-6 V3.1.1:2005?
SIST EN 300 324-6 V3.1.1:2005 relies on EN 300 324-1 for the V5.1 interface specification, EN 300 324-2 for the PICS proforma, and EN 300 324-5 for the network-layer test purposes. It also uses ISO 7498 for OSI layer definitions and ISO/IEC 9646-1, -2, -3, and -5 for conformance testing methodology, ATS specification, TTCN, and test-laboratory requirements. ETS 300 406 and ETR 141 are cited for ETSI testing methodology and TTCN style guidance.
What does the SIST EN 300 324-6 V3.1.1:2005 document contain?
The document contains a figure of the remote test method, a table of V5DL address allocation, and a list of test purposes that the ATS does not implement. It also includes detailed TTCN naming and implementation conventions, which matter when a lab maintains or modifies the ATS.
Annex A provides the ATS in both graphical and machine-processable TTCN forms, so it can be used in test tools. Annex B provides a partial PIXIT proforma with fields for the test laboratory, client, SUT, protocol identification, addresses, timers, procedural information, optional message content, implicit send event procedures, and PICS information.
