SIST EN 300 356-31 V3.0.3:2005 is the Slovenian adoption of ETSI EN 300 356-31 V3.0.3, published by SIST. It specifies the Protocol Implementation Conformance Statement (PICS) proforma for Integrated Services Digital Network (ISDN) Signalling System No.7 ISDN User Part (ISUP) version 3 basic services on the international interface. In practice, it tells suppliers and test teams how to declare which ISUP v3 basic-service capabilities an exchange implements for validation and interoperability work.

What does SIST EN 300 356-31 V3.0.3:2005 specify?

SIST EN 300 356-31 V3.0.3:2005 specifies the validation and conformance test information for ISUP v3 basic call control and signalling procedures defined in EN 300 356-1. It applies to exchanges that have implemented the ISUP v3 protocol specification and is used for validation testing of all exchange types covered by that specification.

The document is organized as follows:

• Scope
• References
• Definitions and abbreviations
• Conformance to the PICS proforma specification
• Annex A - normative PICS proforma

Annex A contains the actual questionnaire-style proforma, including identification fields, the reference specification, global conformance, roles, capabilities, and timers.

What are the key requirements of SIST EN 300 356-31 V3.0.3:2005?

Clause 4 states that a conforming PICS proforma must be technically equivalent to Annex A and must keep the same numbering and order of items. For a buyer or test lab, this means the completed statement has to match the standard structure exactly so answers can be compared consistently.

Clause 4 also requires the PICS to describe an implementation claimed to conform to EN 300 356-1 and to include enough information to identify both the supplier and the implementation. This matters because the conformance statement must be traceable to one specific product or configuration.

Annex A.1 says the supplier completes all spaces in the proforma and may add comments separately. The annex also uses ISO/IEC 9646-7 tabular conventions, so each item has a status such as mandatory, optional, not applicable, or conditional, and the supplier marks support with Y, N, or N/A as appropriate.

Annex A.4.1 uses a single global conformance question: whether all mandatory capabilities are implemented. A "No" answer means the implementation is non-conforming to the reference specification, and any unsupported mandatory capabilities must be identified with an explanation. In practice, this is the high-level pass/fail declaration for the implementation.

Annex A.4.2 to A.4.4 break the PICS into the parts that matter for testing:

• Roles - the exchange may be an originating local exchange, national transit exchange, outgoing international exchange, incoming international exchange, international transit exchange, or destination local exchange. This lets the test team choose the correct behavior set.
• Capabilities - the tables cover connection types, forward address signalling, exchange-role behavior, gateway and interworking behavior, continuity checking, segmentation, in-band tones and announcements, compatibility procedure handling, congestion control, availability control, MTP Pause and Resume, temporary alternative routing, hop counter, and call collect request.
• Timers - the table lists the ISUP timers used by the proforma, with support status and allowed time ranges or fixed values. This is what operators and labs check when they compare a real exchange's timeout settings with the declared capability set.

Several items are conditional, so the PICS answers depend on which roles or functions the implementation supports. That makes the document useful as a structured checklist before conformance testing starts.

What terms does SIST EN 300 356-31 V3.0.3:2005 define?

• Abstract Test Case (ATC) - a complete, independent test case specified at the level of abstraction of an Abstract Test Method.
• Abstract Test Method (ATM) - the abstract description of how an Implementation Under Test (IUT) is tested.
• Abstract Test Suite (ATS) - a suite made up of abstract test cases.
• Implementation Under Test (IUT) - the protocol implementation being examined by testing.
• Means of Testing (MOT) - the equipment and procedures used to derive, select, parameterize, and execute test cases and produce a conformance log.
• Protocol Implementation Conformance Statement (PICS) - a supplier statement showing which capabilities of the protocol are implemented.
• Protocol Implementation eXtra Information for Testing (PIXIT) - supplier information needed by a test laboratory to run the right test suite.
• System Under Test (SUT) - the real open system that contains the IUT.

Who uses SIST EN 300 356-31 V3.0.3:2005?

SIST EN 300 356-31 V3.0.3:2005 is used by telecom equipment suppliers, switch and exchange vendors, test laboratories, and quality or acceptance teams working on ISDN/SS7 interworking. It helps them document the ISUP v3 basic-service capabilities of an exchange before conformance or validation testing, and it gives the test team a consistent way to interpret the declared roles, timers, and optional functions.

Which standards are used with SIST EN 300 356-31 V3.0.3:2005?

• EN 300 356-1 - defines ISUP version 3 basic services, which are the reference capabilities for the PICS.
• EN 300 356-32 - gives the Test Suite Structure and Test Purposes for ISUP v3 basic services.
• EN 300 356-33 - gives the Abstract Test Suite and partial PIXIT proforma for ISUP v3 basic services.
• ITU-T Recommendation Q.784.1 - covers compatibility tests for ISUP basic call testing.
• ISO/IEC 9646-1 - provides the conformance testing concepts and terminology used in the document.
• ISO/IEC 9646-7 - provides the rules for Implementation Conformance Statements and the tabular PICS format.
• ITU-T Recommendation Q.764 - supplies the signalling procedures and timer references used throughout the proforma.
• ITU-T Recommendation E.164 - defines the international public telecommunication numbering plan used for ISDN numbers.

What does the SIST EN 300 356-31 V3.0.3:2005 document contain?

The document contains a structured PICS questionnaire for ISUP v3 basic services, with fields for implementation identity, supplier details, and system configuration. It also contains the global statement of conformance, role selection, capability matrices, and a timer table.

Annex A is the main working part: it is a fill-in proforma rather than a descriptive technical narrative. For testing and certification work, it provides the exact questions that must be answered to declare support for ISUP v3 basic-service behavior.
