SIST EN 300 356-2 V3.2.2:2003 is the Slovenian adoption of ETSI EN 300 356-2 V3.2.2. It specifies additional generic procedures for ISDN supplementary services over the ISDN User Part (ISUP) version 3 of Signalling System No.7 (SS7) for the international interface, based on ITU-T Recommendation Q.730 (1997) with agreed modifications.

What does SIST EN 300 356-2 V3.2.2:2003 specify?

SIST EN 300 356-2 V3.2.2:2003 defines procedures common to multiple ISDN supplementary services on the international ISUP interface. In practice, it gives the shared signalling framework that network operators and switch vendors use when different supplementary services need the same basic call-control handling.

The Scope says the document applies to pan-European ISDN provided by European public telecommunications operators through SS7 for ISUP. It keeps the functions, message formats, codes and exchange actions needed for the international interface, while leaving national-interface specifics and non-ISDN network requirements outside the document.

The document is organised around a common service specification structure and includes two informative annexes plus an informative appendix.

Part	What it covers
Annex A	Signalling flows
Annex B	Interworking aspects
Appendix II	A network option, with the status of an informative annex

What are the key requirements of SIST EN 300 356-2 V3.2.2:2003?

The standard’s main requirement is to provide the shared procedure layer for multiple supplementary services carried over ISUP version 3. That matters because implementers need one common behaviour for setup, signalling and exchange actions before they add service-specific details from the companion parts.

• The Scope limits the document to the international ISDN interface. It does not add protocol requirements for users reached through non-ISDN networks, so integrators must handle those cases separately.
• The Scope also says that national-signalling-interface requirements are outside the document. For practice, this means the standard is aimed at interconnection between networks, not at defining every national implementation detail.
• Functions, formats, codes and actions at originating and destination local exchanges are retained. That is important because international interworking still depends on consistent exchange behaviour at both ends of the call.
• Items marked for national use are included for information in the international specification. If a national network supports them, they are intended to be supported in that way, which helps avoid mismatches at gateways.
• Items marked “Not Required” do not have to be supported. This gives implementers a clear boundary between mandatory shared behaviour and optional items.
• If a national signalling system behaves differently, the international gateway exchange is expected to support both the national and the international network. In practice, gateway design must account for translation and dual behaviour.
• The standard relies on the companion parts of EN 300 356 for the service-specific procedures. Part 1 covers basic services, while the later parts cover individual supplementary services such as CLIP, CLIR, COLP, COLR, TP, UUS, CUG, SUB, MCID, CONF, ECT, diversion services, HOLD, CW, CCBS, 3PTY and CCNR.
• The added document structure includes operational requirements, coding requirements, state definitions, signalling procedures, timer values and dynamic description. That tells readers where to find the procedures, message handling and timing information needed for implementation and test preparation.

What terms does SIST EN 300 356-2 V3.2.2:2003 define?

• Integrated Services Digital Network (ISDN) - A digital network that carries multiple telecommunications services on a common access and signalling framework.
• Signalling System No.7 (SS7) - The signalling system used to set up, control and clear calls and services between exchanges.
• ISDN User Part (ISUP) - The SS7 part that carries call-control signalling for ISDN connections.
• Supplementary service - An added service that works alongside basic call handling, such as number identification, diversion or call waiting.
• Calling Line Identification Presentation (CLIP) - A supplementary service that presents the calling line identity to the called user.
• Explicit Call Transfer (ECT) - A supplementary service that allows a call to be transferred explicitly.
• Protocol Implementation Conformance Statement (PICS) - A conformance document used to declare which functions an implementation supports.

Who uses SIST EN 300 356-2 V3.2.2:2003?

Telecom network operators use this standard when they configure international ISDN interworking and gateway exchanges. Switch manufacturers and protocol implementers use it when they build ISUP support for supplementary services. Test laboratories and quality teams use it to prepare conformance, interoperability and service-interworking checks.

It is also relevant to buyers and project managers who need to confirm that an ISDN signalling platform supports the shared supplementary-service procedures expected on international interfaces.

What changed in SIST EN 300 356-2 V3.2.2:2003 from the previous edition?

This edition is the EN 300 356-2 version aligned with ITU-T Recommendation Q.730 (1997) and published with agreed ETSI modifications. The stated changes include replacement of the Scope and References clauses, updated references to the modified companion EN 300 356 parts, deletion of selected sentences in subclauses 1.3.2 and 1.3.5, addition of a “Not required” subclause title, and insertion of a standard document structure for supplementary-service parts.

What does the SIST EN 300 356-2 V3.2.2:2003 document contain?

The document contains the common signalling procedures for supplementary services, including activation, deactivation and registration, plus actions at originating, transit, gateway and destination exchanges. It also covers interactions with other networks and with other supplementary services, together with timer values and dynamic description.

Annex A provides signalling flows, and Annex B provides interworking aspects. Appendix II is presented as an informative annex for a network option.
