SIST EN 300 356-19 V4.2.1:2004 is the Slovenian adoption of ETSI EN 300 356-19 V4.2.1, based on ITU-T Recommendation Q.734 clause 2 and the 1998 implementors guide, with ETSI modifications. It specifies the stage 3 signalling procedures and switching functions for the Three-Party (3PTY) supplementary service on the ISDN User Part (ISUP) of Signalling System No.7 (SS7) for the international interface. In practice, it is used by telecommunications operators and implementers who need to support 3PTY in pan-European Integrated Services Digital Network (ISDN) speech services.

What does SIST EN 300 356-19 V4.2.1:2004 specify?

SIST EN 300 356-19 V4.2.1:2004 specifies the stage 3 of the Three-Party (3PTY) supplementary service for the pan-European ISDN when the service is provided through SS7 and ISUP. Stage 3 is the signalling protocol and switching-function view, so the document is about how the network behaves, not just what the user sees.

The scope also states what is outside the document. It excludes additional protocol requirements when the service is delivered through a non-ISDN network and additional protocol requirements for the national signalling interface.

What are the key requirements of SIST EN 300 356-19 V4.2.1:2004?

The most important points in SIST EN 300 356-19 V4.2.1:2004 are the service limits, the reference substitutions, and the compatibility coding guidance. Together, these tell an implementer what the international ISUP behaviour must follow and what parts are only informative.

Service scope and applicability

SIST EN 300 356-19 V4.2.1:2004 applies to telecommunication services carrying speech. That matters because the 3PTY procedures in this part are intended for voice-service use, not for all possible bearer or supplementary-service cases.

The document also keeps the functions, formats, codes, messages, signals, and the actions at originating and destination local exchanges for the international interface. In practice, this means the international gateway and local exchange behavior remains part of the specification even where some items are marked for national use.

Reference and behavior rules

SIST EN 300 356-19 V4.2.1:2004 replaces several ITU-T references with ETSI or EN versions, including the basic ISUP parts, the ISDN supplementary-service framework, and the DSS1 signalling reference used elsewhere in the series. This is important for implementation because it tells readers which companion ETSI documents to follow instead of the original ITU-T texts.

Subclause 2.5 adds a note that the global call reference associated with calls on the multi-party legs is for further study. For implementers, that means this particular point is not finalized as a working rule in this part.

Subclause 2.8 is marked as informative only. That tells the reader not to treat that content as a normative requirement.

Compatibility information

Annex ZA gives coding guidance for the compatibility information associated with the generic notification parameter. In practice, this is the place to look when an implementation needs to encode or interpret compatibility-related signalling consistently.

What terms does SIST EN 300 356-19 V4.2.1:2004 define?

• Integrated Services Digital Network (ISDN) - The digital network context for the service; the document uses it as the telecom environment for 3PTY.
• Signalling System No.7 (SS7) - The signalling system used to carry the protocol procedures between network nodes.
• ISDN User Part (ISUP) - The SS7 part that handles ISDN call control and supplementary-service signalling.
• Three-Party (3PTY) - The supplementary service covered by this part, for calls involving three parties.
• Stage 3 - The signalling-protocol and switching-function level in the ITU-T three-level service description model.
• Digital Subscriber Signalling System No. one (DSS1) - The signalling system named in the references for related ISDN user-side protocol work.

Who uses SIST EN 300 356-19 V4.2.1:2004?

SIST EN 300 356-19 V4.2.1:2004 is used by public telecommunications operators, switch and signalling implementers, and standards engineers working on ISDN interconnection. It is also relevant to people maintaining international gateway exchanges, because the document keeps the international-interface behaviour for 3PTY. Quality and conformance teams use it when they need to check that the signalling procedures and compatibility coding follow the EN 300 356 ISUP framework.

What changed in SIST EN 300 356-19 V4.2.1:2004 from the previous edition?

The document history lists earlier publications of ETS 300 356-19, including the first edition, Corrigendum 1, V3.1.3, and V4.1.1, before the V4.2.1 publication in July 2001. The text also states that the present document is part 19 of the multi-part ISUP version 4 series and that it applies the modifications to ITU-T Recommendation Q.734 clause 2 and the 1998 implementors guide.

What does the SIST EN 300 356-19 V4.2.1:2004 document contain?

The document contains the endorsed text of ITU-T Recommendation Q.734 clause 2 with ETSI modifications, including a Scope and References section inserted at the start of clause 2. It also contains a reference-replacement table that maps ITU-T citations to ETSI/EN documents.

Annex ZA provides informative coding guidance for compatibility information. The history section records the publication trail for the standard, which helps users identify the version they are working from.
