SIST EN 300 369-6 V1.5.1:2005 is the network-side test specification for the Integrated Services Digital Network (ISDN) Digital Subscriber Signalling System No. one (DSS1) protocol Explicit Call Transfer (ECT) supplementary service. It defines the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for implementations at the T reference point or the coincident S/T reference point, so it is the document used when checking how a network implementation behaves in ECT test conditions.

What does SIST EN 300 369-6 V1.5.1:2005 specify?

SIST EN 300 369-6 V1.5.1:2005 specifies how to test the network side of ECT against the stage 3 protocol standard EN 300 369-1. It gives the abstract test suite, the partial PIXIT proforma, and the reporting forms needed to run and record conformance testing.

The document is organized into clauses for scope, references, definitions and abbreviations, the abstract test method, untestable test purposes, ATS conventions, the ATS to TP map, conformance statements, and required test configurations. It then provides annexes for the PCTR proforma, the partial PIXIT proforma, the ATS itself, a list of changes from the previous edition, and a bibliography.

What are the key requirements of SIST EN 300 369-6 V1.5.1:2005?

SIST EN 300 369-6 V1.5.1:2005 sets out how the network IUT is tested, how the ATS is encoded, and what a conforming test realization and test report must contain. In practice, this tells a test laboratory what to configure, what to log, and how to claim conformance.

Abstract test method and test roles

Clause 4 uses a multi-party test method. The Main Test Component (MTC) controls the test, while the Parallel Test Components (PTCs) behave as remote parties and report results through Coordination Messages (CMs). For the reader, this means network behavior is checked in a realistic call environment, not as a single isolated interface.

Clause 4 distinguishes served-user test cases from remote-user test cases. In served-user cases, the verdict depends on what happens at the interface under test; in remote-user cases, the verdict can also depend on the served user attached to the MTC. That matters because the tester must know which side can influence the result.

ATS conventions and encoding

Clause 6 states that the ATS uses the TTCN version defined in TR 101 101. It also uses ASN.1 where that is needed for data structures and protocol types.

Clause 6 defines two encoding modes for ASN.1: the default ISDN encoding and Basic Encoding Rules (BER) only where explicitly marked. It also says all ASN.1 type constraints of type Component are encoded with BER. This matters because the same abstract test data may need different encodings depending on the message being checked.

Mapping and conformance

Clause 7 gives a one-to-one map between test purposes and test cases. That helps a laboratory trace each executed test back to the stated purpose.

Clauses 8 to 10 define what conformance means for the PCTR, the PIXIT, and the ATS itself. A conforming PCTR must follow Annex A, a conforming PIXIT must be technically equivalent to Annex B, and a conforming ATS realization must be technically equivalent to Annex C.

Test configurations

Clause 11 lists the required SUT configurations for specific test groups. It covers settings such as ECT subscription, HOLD subscription, connected number presentation, loop checking, link identification, and internal restrictions. In practice, the tester must prepare the network in the correct state before each group of cases is run.

What terms does SIST EN 300 369-6 V1.5.1:2005 define?

• Abstract Test Method (ATM) - The testing approach used to drive and observe the network through multiple components.
• Abstract Test Suite (ATS) - The complete set of abstract test cases and their structure for ECT network testing.
• Protocol Conformance Test Report (PCTR) - The report form used to record the outcome of conformance testing.
• Protocol Implementation eXtra Information for Testing (PIXIT) - The implementation-specific information needed to prepare the tests.
• System Under Test (SUT) - The implementation being configured and tested.
• Main Test Component (MTC) - The test component that controls the test and assigns verdicts.
• Parallel Test Component (PTC) - A component that simulates remote behavior during the test.
• Tree and Tabular Combined Notation (TTCN) - The notation used to express the ATS.

Who uses SIST EN 300 369-6 V1.5.1:2005?

SIST EN 300 369-6 V1.5.1:2005 is used by conformance test laboratories, test tool developers, network equipment vendors, and quality or acceptance teams that need to verify ECT behavior on an ISDN network interface. It is also used by clients of test laboratories who need a PCTR or a completed PIXIT for a specific implementation.

What changed in SIST EN 300 369-6 V1.5.1:2005 from the previous edition?

SIST EN 300 369-6 V1.5.1:2005 replaces EN 300 369-4 V1.2.4. Annex D records the stated changes: a new L2_INIT parameter was added, several test cases and steps were corrected, one call-reference-related item was revised for certain ECT_N05 cases, the RL1 constraint was changed, and the PIXIT was updated.

Which standards are used with SIST EN 300 369-6 V1.5.1:2005?

• EN 300 369-1 - The protocol specification for ECT; it is the protocol basis that the ATS tests.
• EN 300 369-2 - The PICS proforma specification; Annex B references it for implementation statements.
• EN 300 369-5 - The TSS & TP specification for the network; it provides the test purposes mapped to this ATS.
• EN 300 196-1 - The generic functional protocol for supplementary services, used for protocol context and behavior.
• TR 101 101 - The TTCN interim version used for the ATS notation.
• ISO/IEC 8825-1 - The ASN.1 encoding rules reference for BER.
• ISO/IEC 9646 (all parts) - The conformance testing methodology and framework used for testing, reports, and realization.

What does the SIST EN 300 369-6 V1.5.1:2005 document contain?

SIST EN 300 369-6 V1.5.1:2005 contains a TTCN ATS in graphical and machine-processable form, plus the associated test report and PIXIT proformas. It also includes the test method description, encoding conventions, test-case mapping, and specific network configurations needed before executing cases.

Annex A provides the PCTR structure used to record identification, environment, conformance status, summaries, and observations. Annex B provides the PIXIT questions for protocol details, SUT setup, timer values, and information element codings. Annex C contains the ATS files, including the TTCN.GR and TTCN.MP representations, which are the actual abstract test cases used to derive executable tests.
