SIST EN 300 356-10 V3.1.3:2003 is the Slovenian adoption of EN 300 356-10 V3.1.3 for Integrated Services Digital Network (ISDN) signalling. It specifies the stage three signalling and switching procedures for the Subaddressing (SUB) supplementary service on the international ISDN interface using Signalling System No. 7 (SS7) and ISDN User Part (ISUP) version 3. It is aimed at operators, switch and protocol implementers, and test teams that need to support SUB in international interconnections.

What does SIST EN 300 356-10 V3.1.3:2003 specify?

SIST EN 300 356-10 V3.1.3:2003 specifies the stage three of the SUB supplementary service for pan-European ISDN over ISUP. In practice, that means it defines the protocol procedures and switching functions needed to carry the service across the international interface.

The document is part 10 of a multi-part EN 300 356 series. It sits alongside the parts for basic services, other supplementary services, and the related PICS, TSS&TP, ATS and PIXIT specifications for basic and supplementary services.

The scope text also sets clear boundaries:

• it does not cover the extra protocol requirements when the service is offered through a non-ISDN network
• it does not cover the extra protocol requirements for the national signalling interface
• it keeps the functions, message formats, codes and actions at originating and destination local exchanges
• it includes items marked for national use for informative purposes on the international interface

What are the key requirements of SIST EN 300 356-10 V3.1.3:2003?

SIST EN 300 356-10 V3.1.3:2003 is a stage three specification, so its main job is to define signalling behaviour and switching actions, not user-facing service description. For implementers, that means the document is about what the network must exchange and how nodes must react.

• SUB service purpose - The SUB supplementary service allows the called user to extend the addressing capacity beyond the ISDN number. This matters when the normal number is not enough to reach the intended endpoint.
• International interface focus - The standard applies to international interconnection only. A reader uses it when implementing or checking cross-border ISDN signalling.
• Basic call relationship - The document adds generic procedures to those in the basic call. That means SUB is implemented as an addition to call handling, not as a separate call type.
• Stage three responsibilities - Stage three identifies the protocol procedures and switching functions needed to support the service, in line with CCITT Recommendation I.130. Practically, this tells engineers to implement node behaviour and message handling, not service policy.
• Retained network functions - The specification keeps the functions, formats, codes and procedures used by originating and destination local exchanges. This helps ensure the service works consistently at the network edges.
• National-use items - Formats, codes and procedures marked for national use appear for informative purposes. If a national network supports them, they are to be supported in that manner on the international interface.
• Gateway handling - Where a national signalling system behaves differently, the international gateway exchange is to support both the national and the international network. This is important for interoperability at the border node.

What terms does SIST EN 300 356-10 V3.1.3:2003 define?

• Integrated Services Digital Network (ISDN) - A digital network framework used here as the service environment for SUB.
• Signalling System No. 7 (SS7) - The signalling system used to carry the ISUP procedures.
• ISDN User Part (ISUP) - The SS7 user part used for ISDN call control and supplementary services on the international interface.
• Subaddressing (SUB) - The supplementary service that extends the called user’s addressing capacity beyond the ISDN number.
• Stage 1 - The overall service description from the user’s point of view.
• Stage 2 - The description of functional capabilities and information flows needed to support the service.
• Stage 3 - The signalling protocol and switching specification needed to implement the service.
• Digital Subscriber Signalling System No. one (DSS1) - The signalling protocol family referenced by the companion SUB documents and related network layer specification.

Who uses SIST EN 300 356-10 V3.1.3:2003?

SIST EN 300 356-10 V3.1.3:2003 is used by telecom operators, switching system vendors, signalling protocol implementers and conformance test teams working with ISDN international interconnections. It is especially relevant when a network must support the SUB supplementary service across an ISUP-based interface.

It also matters to engineers responsible for gateway exchanges, since the text addresses cases where national signalling behaviour differs from the international one. Quality and interoperability teams use it to check that the implemented procedures, message handling and reference mappings match the expected stage three behaviour.

What changed in SIST EN 300 356-10 V3.1.3:2003 from the previous edition?

SIST EN 300 356-10 V3.1.3:2003 records publication as ETS 300 356-10 V3.1.1 in February 1995, followed by V3.1.2 and then V3.1.3 in August 1998. The text was approved by ETSI with agreed modifications to ITU-T Recommendation Q.731, clause 8 (1992).

The document marks new or modified text with sidebars, and uses underlining and strike-out where detailed changes need to be highlighted.

Which standards are used with SIST EN 300 356-10 V3.1.3:2003?

• CCITT Recommendation I.130 - provides the method for characterizing telecommunication services and network capabilities.
• ETS 300 059 - gives the SUB service description.
• ETS 300 060 - gives the SUB functional capabilities and information flows.
• ETS 300 061-1 - gives the DSS1 protocol specification for SUB.
• ETS 300 121 - provides the ISUP version 1 basis for international ISDN interconnections.
• EN 300 356-1 - provides the modified ISUP version 3 basic services reference.
• EN 300 356-2 - provides the modified ISUP version 3 ISDN supplementary services reference.
• EN 300 403-1 - provides the DSS1 signalling network layer for circuit-mode basic call control.

These references supply the service model, signalling background and companion protocol definitions that the SUB stage three text builds on.

What does the SIST EN 300 356-10 V3.1.3:2003 document contain?

The document contains the stage three text for SUB, together with an inserted Scope and Normative references section at the start of clause 8. It also contains a reference-replacement table that maps older ITU-T and CCITT references to ETSI and EN documents used in the modified text.

For implementers, the useful content is the protocol and switching specification, plus the mapped references that show which companion documents to use for the service description, functional model, basic call control and related ISUP material. The history and endorsement material show how the standard was adopted and published by ETSI.
