SIST EN 300 347-3 V3.1.1:2005 is the Slovenian adoption of ETSI EN 300 347-3 Version 3.1.1. It specifies the Test Suite Structure and Test Purposes (TSS&TP) for the network layer on the Access Network (AN) side of a V5.2 interface between a digital Local Exchange (LE) and an AN.

The document is used to plan and judge conformance tests, with the goal of showing that AN and LE implementations from different manufacturers can interoperate over the V5.2 interface.

What does SIST EN 300 347-3 V3.1.1:2005 specify?

SIST EN 300 347-3 V3.1.1:2005 specifies the network-layer and parts of the system-management test purposes for the AN side of a V5.2 interface. It defines how the test suite is structured and what each test purpose is intended to verify, using the ISO/IEC conformance testing methodology.

The scope is limited to the procedures described in EN 300 347-1 and is meant to be read together with that part and with the PICS proforma in EN 300 347-2. The foreword places it in a multi-part series for the V5.2 interface, covering the interface specification, PICS, TSS&TP, ATS, and the data-link and physical layers.

What are the key requirements of SIST EN 300 347-3 V3.1.1:2005?

Test structure and coverage

SIST EN 300 347-3 V3.1.1:2005 organizes testing into protocol groups for control, PSTN, link control, BCC, and protection, and into main test groups for basic interconnection, capability, valid behaviour, inopportune behaviour, invalid behaviour, and timer expiry/counter mismatch. In practice, this tells a test lab which protocol area each case belongs to and how broad the intended coverage is.

The test purposes are not written as a full state-by-state verification of every procedure. Instead, they step through the finite state machines and use selected examples to cover the important behaviours efficiently.

Setup, configuration, and state handling

SIST EN 300 347-3 V3.1.1:2005 relies on PICS items to decide which startup and port configurations apply, including support for PSTN, ISDN-BA, ISDN-PRA, multiple link configurations, and accelerated port state alignment. That matters because the same test suite is run differently depending on what the implementation actually supports.

The document also defines preambles, postambles, initial states, and status verification steps. In practice, a tester must bring the Implementation Under Test (IUT) into the right state before each test and return it to the initial state afterward.

Protocol-specific behaviours

For the control protocol, the test purposes cover blocking and unblocking for PSTN, ISDN-BA, and ISDN-PRA ports, including special handling for accelerated alignment where applicable. For the link control protocol, they cover link unblock, link identification, local and remote blocking, persistent and non-persistent link failures, and the effect of link control on protection switching.

For BCC, the document covers allocation, de-allocation, audit, AN internal failure notification, and error handling. For protection, it covers sequence number reset and standard or dedicated switch-over procedures, including cases triggered by link failure, absence of flags, or data-link failure.

Timers, counters, and error handling

The ATS defines timers and counters for repeated messages and timeout behaviour, and it gives the test approach for message repetition and counter mismatch. This is important because conformance is not just about one correct message, but also about what happens when timers expire or acknowledgements are missing or wrong.

What terms does SIST EN 300 347-3 V3.1.1:2005 define?

• Access Network (AN) - the network side of the V5.2 interface that is tested by this document.
• Local Exchange (LE) - the exchange side that connects to the AN over the V5.2 interface.
• Implementation Under Test (IUT) - the equipment or system being checked for conformance.
• Test Suite Structure and Test Purposes (TSS&TP) - the organization of the tests and the statement of what each test is intended to verify.
• Abstract Test Suite (ATS) - the test suite framework that contains the test steps, timers, and counters used in execution.
• Protocol Implementation Conformance Statement (PICS) - the configuration statement used to decide which options and test cases apply.
• Finite State Machine (FSM) - the state model used for protocol and port behaviour during testing.

Who uses SIST EN 300 347-3 V3.1.1:2005?

SIST EN 300 347-3 V3.1.1:2005 is used by equipment manufacturers, conformance test laboratories, interoperability teams, and quality engineers working on V5.2 interface implementations. It is also useful for buyers and integrators who need to check that a supplier’s AN or LE implementation can be tested against the right protocol behaviours before deployment.

In practice, users apply it when preparing test configurations, selecting applicable test purposes from the PICS, and validating control, link, BCC, and protection behaviour.

What changed in SIST EN 300 347-3 V3.1.1:2005 from the previous edition?

SIST EN 300 347-3 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 300 347-3 V3.1.1:2005?

• EN 300 347-1 - provides the V5.2 interface specification and the protocol procedures that the tests exercise.
• EN 300 347-2 - provides the PICS proforma used to declare the implementation’s supported options.
• ETS 300 324-3 - provides the matching V5.1 part 3 format and shared clauses that this document references directly.
• EN 300 347-7 - covers the V5.2 data-link layer test suite and is referenced for link-failure cases outside this part.
• ISO/IEC 9646-1 - supplies the general conformance testing methodology and framework.
• ISO/IEC 9646-2 - supplies the abstract test suite specification method.

What does the SIST EN 300 347-3 V3.1.1:2005 document contain?

The document contains the test suite structure, test-group mapping, test-step structure, default handling, and the detailed test purposes for control, PSTN, link control, BCC, and protection. It also includes tables for protocol entities, timers and counters, and test-purpose naming conventions.

It provides a startup flow diagram, state-transition descriptions, message and information-element listings, and many case-by-case TP statements for normal, exceptional, and error conditions. These are the parts a lab uses to build executable tests, trace expected messages, and verify protocol state changes.
