SIST EN 300 369-3 V1.3.1:2005 is the user-side Test Suite Structure and Test Purposes (TSS&TP) specification for the Explicit Call Transfer (ECT) supplementary service in Integrated Services Digital Network (ISDN) using the Digital Subscriber Signalling System No. one (DSS1) protocol. It tells test developers what to verify at the T reference point or coincident S and T reference point for implementations conforming to EN 300 369-1. It is used to build and select conformance tests, not to define the ECT protocol itself.

What does SIST EN 300 369-3 V1.3.1:2005 specify?

SIST EN 300 369-3 V1.3.1:2005 specifies the test structure and the test purposes for the user side of ECT. The document is organized into clauses for the scope, references, definitions and abbreviations, the Test Suite Structure, Test Purposes, compliance, and requirements for a comprehensive testing service, plus an informative annex on changes.

Clause 4 presents the TSS for the ECT user side. Clause 5 gives the detailed Test Purposes, including the naming rules and the test strategy. Clause 6 states the conditions for a conforming Abstract Test Suite (ATS), and Clause 7 names the minimum test method for a comprehensive testing service.

Annex A is informative and records the change history and the renumbering of Test Purposes from earlier editions.

What are the key requirements of SIST EN 300 369-3 V1.3.1:2005?

Test Suite Structure and naming

SIST EN 300 369-3 V1.3.1:2005 defines a structured set of ECT test groups for User(S/T) and User(T). The groups cover served-user and remote-user behaviour, including implicit linkage, explicit linkage, confirmation of call transfer, loop-checking, and transfer in private and public network cases. In practice, this gives test labs a map from service features to test groups.

The Test Purposes use a fixed naming convention: the service name, the IUT type, the test group, and a sequence number. This matters because it lets PICS-based selection and test reporting stay consistent across tools and laboratories.

How the Test Purposes are built

The Test Purposes are based on EN 300 369-1 and are written to be internally consistent and easy to compare. The strategy states that only requirements seen from the T or coincident S and T reference point are considered, and whether a test case can actually be built is not part of the selection criterion. In practice, the document is about what must be tested, even when a particular Abstract Test Method cannot cover every item.

User(S/T) behaviour

For User(S/T), the document covers a served user who handles two calls and may transfer them using implicit or explicit linkage procedures. The TP set checks valid and invalid FACILITY exchanges, including EctExecute, EctLinkIdRequest, ExplicitEctExecute, return result, return error, and reject handling, as well as confirmation of transfer by DISCONNECT and RELEASE behavior. For an implementer, this means the equipment must react correctly to successful, error, and rejection cases while preserving the expected call states.

The same clause set also includes a case for sending subaddress information in response to RequestSubaddress or EctInform. That tells the reader that subaddress transfer is part of the user-side behaviour covered by this test specification.

User(T) behaviour

For User(T), the document covers transfer in the private network and in the public network, including the mechanism to avoid looping of uncontrolled circuits. It also includes EctInform behavior and subaddress transfer in the remote-user-connected case. In practice, this distinguishes whether the private network performs the transfer itself or invokes ECT in the public network.

Compliance and testing service

Clause 6 says a compliant ATS must include the testable Test Purposes, use a suitable subset of the TSS, keep the same naming conventions, preserve the PICS relationship, and comply with ISO/IEC 9646-2. Clause 7 says the minimum method for a comprehensive testing service is the Remote test method from ISO/IEC 9646-2. That is the practical rule for organizations that claim to test user equipment against EN 300 369-1.

What terms does SIST EN 300 369-3 V1.3.1:2005 define?

• Abstract Test Suite (ATS) - the set of abstract test cases used for conformance testing.
• Protocol Implementation Conformance Statement (PICS) - the statement that lists which protocol features an implementation supports.
• Protocol Implementation eXtra Information for Testing (PIXIT) - extra implementation information needed to run or adapt tests.
• Implementation Under Test (IUT) - the device or system whose conformance is being tested.
• Test Purpose (TP) - a defined objective for one test requirement.
• Explicit Call Transfer (ECT) - the supplementary service being tested, where one call is transferred to another party.
• Digital Subscriber Signalling System No. one (DSS1) - the signalling protocol used on the ISDN user-network interface.

Who uses SIST EN 300 369-3 V1.3.1:2005?

SIST EN 300 369-3 V1.3.1:2005 is used by conformance test labs, protocol engineers, and equipment vendors working on ISDN user equipment. Quality managers and buyers use it to understand what ECT behaviour can be verified and how test selection links to the PICS and PIXIT. It is also relevant to organizations providing remote testing services for equipment claiming conformance to EN 300 369-1.

What changed in SIST EN 300 369-3 V1.3.1:2005 from the previous edition?

Annex A states that the update consists of editorial changes and a renumbering of the Test Purposes from earlier editions of ETS 300 369-3 and ETS 300 369-4. The annex also provides a mapping between old and new TP identifiers, and notes that equivalent identifiers are not necessarily identical.

Which standards are used with SIST EN 300 369-3 V1.3.1:2005?

• EN 300 369-1 - the ECT protocol specification that the test purposes are based on.
• EN 300 369-2 - the PICS proforma specification used for test selection.
• ETSI EN 300 369-4 - the ATS and PIXIT proforma specification for the user side.
• ISO/IEC 9646-1 - the conformance testing framework that defines ATS, IUT, PICS, PIXIT, and TP concepts.
• ISO/IEC 9646-2 - the abstract test suite specification and test method rules.
• EN 300 141-2 - the HOLD PICS reference used where held-call support is relevant.
• EN 300 196-1 - the generic supplementary services protocol reference used for component and state definitions.
• EN 300 403-1 - the basic call control reference used for Call Reference definitions.
• ITU-T I.411, I.112, and I.210 - ISDN reference configurations, vocabulary, and service principles.

What does the SIST EN 300 369-3 V1.3.1:2005 document contain?

The document contains a TSS figure, TP naming rules, and a large set of detailed user-side test purposes written as message/state sequences. Those test purposes cover valid and invalid FACILITY, DISCONNECT, CONNECT, and RELEASE handling, with call states such as U04, U07, U10, and U19. It also includes cases for implicit and explicit linkage, transfer confirmation, loop testing, and subaddress transfer. Annex A provides the change map for renamed test purposes.
