SIST ETS 300 347-7:1997 is the Slovenian adoption of ETS 300 347-7 Edition 1 from ETSI. It specifies the Test Suite Structure and Test Purposes (TSS&TP) for the data link layer of the V5.2 interface used between an Access Network (AN) and a Local Exchange (LE). The standard is meant for people who need to prepare, review, or run conformance tests for V5.2 data link layer implementations.
What does SIST ETS 300 347-7:1997 specify?
SIST ETS 300 347-7:1997 defines how to test the Data Link Layer (DLL) of the V5.2 interface, with emphasis on conformance testing and interoperability between AN and LE equipment. It covers only the procedures described in ETS 300 347-1 and uses ISO/IEC 9646-1 and ISO/IEC 9646-2 as the testing-method basis.
The document is organized as follows:
- Clause 1 - Scope
- Clause 2 - Normative References
- Clause 3 - Definitions and abbreviations
- Clause 4 - Test Suite Structure (TSS)
- Clause 5 - Test Purposes (TP)
- Annex A - Informative bibliography
In practice, this means the standard tells test developers what the abstract test suite must contain and what each test purpose is intended to check, rather than giving a full executable test suite.
What are the key requirements of SIST ETS 300 347-7:1997?
SIST ETS 300 347-7:1997 is built around a shared conformance-test structure and a specific startup and configuration model for the V5.2 DLL. The most important points are the test structure, the startup sequence, the assumed initial state, and the way the implementation under test (IUT) is configured for AN and LE testing.
Test structure and common test material
Clause 4 defines the Abstract Test Suite (ATS) structure: test groups, test-step structure, defaults, Abstract Service Primitives (ASPs), Protocol Data Units (PDUs), and timers/counters. Many of these subclauses are identical to ETS 300 324-7, so the same test logic is reused where V5.2 behaves like V5.1. For a reader, this means the framework is standardized and much of the test choreography is already aligned with earlier V5 testing.
Start-up and configuration
Clause 4.3.1.1 ties V5 interface start-up to the configuration declared in the Protocol Implementation Conformance Statement (PICS). The items TSPC_PSTN, TSPC_ISDNBA, and TSPC_ISDNPRA identify whether PSTN ports, ISDN-BA user ports, or ISDN-PRA user ports are supported, and at least one of them must be set. In practice, the tester must know which port types are provisioned before the start-up sequence can be applied.
The start-up flow includes link establishment, variant and interface identification, link identification, and restart handling. Lower Tester 1 (LT1) waits for a restart complete from the IUT before sending its own restart complete. That matters because the test relies on a defined exchange order, not just on the link coming up.
What is actually tested
Clause 5 limits the DLL test scope to the Control DL. The standard assumes that the PSTN DL, Protection DL, Link Control DL, and Bearer Channel Connection (BCC) DL implementations are identical to the Control DL implementation, and the supplier must declare that in the PIXIT. If that assumption is valid, the Control DL test purposes can be reused for the other data links.
Clause 5 also states that only one of the ISDN-BA or ISDN-PRA configurations is tested for LAPV5-EF, because their requirements are assumed to be the same. For a test plan, this reduces duplicate coverage.
Initial state and test setup
The initial state for V5 DLL testing is state 7.0, "multiple frame established", and the IUT shall be brought to that state at the start and end of a test. Clause 5.1.6 then defines the data configuration for AN and LE testing, including supported port types and a single 2 Mbit/s link. For engineers and labs, this is the practical setup rule that shapes the test environment.
What terms does SIST ETS 300 347-7:1997 define?
- Access Network (AN) - The network side that connects subscriber access to the local exchange and is one side of the V5.2 interface.
- Local Exchange (LE) - The exchange side of the V5.2 interface.
- Implementation Under Test (IUT) - The equipment or system being evaluated by the conformance tests.
- Protocol Implementation Conformance Statement (PICS) - The declaration used to state which options and port types the IUT supports.
- Protocol Implementation eXtra Information for Testing (PIXIT) - The additional implementation information needed to run the tests correctly.
- Abstract Test Suite (ATS) - The structured set of abstract test cases and test steps used for conformance testing.
- Abstract Service Primitive (ASP) - An abstract representation of a service interaction used in the test model.
- Protocol Data Unit (PDU) - The unit of protocol information exchanged in the abstract test model.
Who uses SIST ETS 300 347-7:1997?
SIST ETS 300 347-7:1997 is used by equipment suppliers for AN and LE implementations, especially when they need to declare and verify DLL conformance on V5.2 interfaces. Test laboratories use it to build conformance tests, choose the right start-up sequence, and set up the IUT correctly.
It is also relevant to quality managers, buyers, and network operators who need to check whether a product supports the right V5.2 data link options and whether its declared configuration matches the test conditions. In practice, the document helps align product declarations, test setup, and interoperability checks.
What changed in SIST ETS 300 347-7:1997 from the previous edition?
SIST ETS 300 347-7:1997 corresponds to ETS 300 347-7 Edition 1.
Which standards are used with SIST ETS 300 347-7:1997?
- ETS 300 347-1 - Defines the V5.2 interface and the DLL sublayers and procedures that this part tests.
- ETS 300 347-2 - Provides the PICS proforma and the port-option items used to configure the IUT for testing.
- ETS 300 324-7 - Supplies the V5.1 DLL test definitions that are reused where V5.2 test logic is the same.
- ETS 300 125 - Gives the ISDN data link layer basis that the covered procedures rely on.
- ISO/IEC 9646-1 - Provides the general conformance-testing concepts and framework.
- ISO/IEC 9646-2 - Provides the Abstract Test Suite specification method used here.
- ETS 300 347-8 - The companion V5.2 data link layer part that contains the ATS and partial PIXIT proforma.
What does the SIST ETS 300 347-7:1997 document contain?
SIST ETS 300 347-7:1997 contains the TSS structure, the test-step categories, and the test-purpose framework for DLL testing. It also gives the start-up flow for the V5.2 interface in Figure 1, which is useful when setting up a lab test or mapping the required exchange sequence.
Clause 5 organizes the test purposes for LAPV5-EF and LAPV5-DL, and it explains the test strategy, initial state, and configuration assumptions behind those purposes. Annex A provides an informative bibliography for further context.

1 Scope
This seventh part of ETS 300 347 contains the Test Suite Structure and Test Purposes (TSS&TP) for the
Data Link Layer (DLL) of the V5.2 Interface.
The objective of this ETS is to provide conformance tests giving a high probability of inter-operability of the
DLL of an Access Network (AN) and a Local Exchange (LE) infrastructure. This ETS covers only the
procedures described in ETS 300 347-1 [3] which are based upon ETS 300 125 [1].
ISO/IEC 9646-1 [5] and ISO/IEC 9646-2 [6] are used as the basis for the test methodology.
For test definitions of protocol functions which are tested in V5.2 the same way as in V5.1, only reference
is made to ETS 300 324-7 [2].
ETS 300 347-1 [3] defines the sublayers of the DLL, i.e. Link Access Protocol for V5 interface (LAPV5)
Data Link sublayer (LAPV5-DL), LAPV5 Envelope Function sublayer (LAPV5-EF) and the mapping
function (see ETS 300 347-1 [3], figure 6, which illustrates this approach). Regarding the conformance
testing, these sublayer functions are not tested separately. The test purposes defined in clause 5 cover
testing of the LAPV5-DL (control protocol only), LAPV5-EF and the mapping function. The AN frame relay
function is tested in co-operation with a generic test of an Integrated Services Digital Network (ISDN)
D-channel.
The limitation of the DLL test to the Control DL is based on the assumption that the Public Switched
Telephone Network (PSTN) DL, the Protection DL, the Link control DL and the Bearer Channel
Connection (BCC) DL implementations are identical with the Control DL implementation. This needs to be
declared by the Implementation Under Test (IUT) supplier. Otherwise, the test purposes defined for the
Control DL may be used for the other DLs as well.
