SIST EN 300 356-4 V3.1.3:2003 is the Slovene adoption of ETSI EN 300 356-4 Version 3.1.3. It specifies the stage three signalling and switching procedures for the Calling Line Identification Restriction (CLIR) supplementary service on the international Integrated Services Digital Network (ISDN) interface, using Signalling System No.7 (SS7) and the ISDN User Part (ISUP). It is aimed at people who implement, operate, or test ISDN interconnection and supplementary service signalling.

What does SIST EN 300 356-4 V3.1.3:2003 specify?

SIST EN 300 356-4 V3.1.3:2003 specifies the stage three of CLIR for pan-European ISDN as provided through the SS7 protocol for ISUP. In practice, that means the document focuses on the network procedures and switching behaviour needed to support the service between networks.

The foreword places this part within the EN 300 356 series for ISUP version 3. Part 4 covers CLIR, while the series also includes parts for basic services, other supplementary services, and test specifications.

What are the key requirements of SIST EN 300 356-4 V3.1.3:2003?

The core requirement in clause 4 is that CLIR is handled as a stage-three service specification. That matters because implementers need to follow the signalling and switching behaviour, not just the user-facing service description.

Clause 4 states that the CLIR supplementary service lets the calling party prevent presentation of its ISDN number to the called party. In operational terms, exchanges and gateways must support number-withholding behaviour when CLIR is invoked.

Clause 4 limits the scope to the international interface. It keeps the extra protocol requirements for a non-ISDN user network and for the national signalling interface outside the described procedures, so the document is primarily for international interconnection design.

Clause 4 also retains the functions, formats, codes, and actions at originating and destination local exchanges. For implementers, that means the international specification still preserves the call-handling elements that local exchanges must perform at each end.

The document includes formats, codes, and procedures marked for national use for informative purposes. If those items are supported inside a national network and an operator’s network, the text proposes that they should be supported in that same manner, which helps maintain predictable interworking.

Clause 4 links the service to the stage 1 and stage 2 descriptions in ETS 300 090 and ETS 300 091. This matters because service planning, functional behaviour, and signalling behaviour are split across the three stages and must be aligned.

Annex ZA gives recommended coding for compatibility information for the generic number parameter. In practice, this is the part to consult when a network has to encode how number information should be handled across exchanges, including pass-on, discard, notification, and interworking behaviour.

What terms does SIST EN 300 356-4 V3.1.3:2003 define?

Integrated Services Digital Network (ISDN) is the digital network environment for the service, where voice and signalling functions are carried over a standardized digital infrastructure.

Signalling System No.7 (SS7) is the signalling system used to carry call control and supplementary service information between network nodes.

ISDN User Part (ISUP) is the SS7 application used for ISDN call signalling on the international interface.

Calling Line Identification Restriction (CLIR) is the supplementary service that allows the calling party to stop its ISDN number from being presented.

Calling Line Identification Presentation (CLIP) is the related service that presents the calling line identity; it appears in the series context and references.

Digital Subscriber Signalling System No. one (DSS1) is the signalling protocol referenced for the user-side ISDN signalling environment.

Who uses SIST EN 300 356-4 V3.1.3:2003?

SIST EN 300 356-4 V3.1.3:2003 is used by ISDN network operators, switching-system vendors, signalling engineers, and interoperability test teams. They use it when designing or verifying international gateways, local exchange behaviour, and supplementary service support for CLIR.

It is also relevant to quality managers and buyers who need to check that equipment or network functions match the ISUP-based international interface requirements for CLIR.

What changed in SIST EN 300 356-4 V3.1.3:2003 from the previous edition?

The document history records earlier publications as ETS 300 356-4 V3.1.1 and ETS 300 356-4 V3.1.2 before the current V3.1.3 publication. The present text is the V3.1.3 edition.

Which standards are used with SIST EN 300 356-4 V3.1.3:2003?

• CCITT Recommendation I.130 - provides the three-stage method used to describe telecommunication services.
• ETS 300 090 - gives the stage 1 service description for CLIR.
• ETS 300 091 - gives the stage 2 functional capabilities and information flows for CLIR and CLIP.
• ETS 300 093-1 - provides the DSS1 protocol specification for CLIR.
• ETS 300 121 - provides the earlier ISUP basis for international ISDN interconnections.
• EN 300 356-1 - provides the modified ISUP version 3 basics for international interface signalling.
• EN 300 356-2 - provides the modified ISUP supplementary services framework used by this part.
• EN 300 403-1 - provides the DSS1 signalling network layer protocol specification for circuit-mode basic call control.

What does the SIST EN 300 356-4 V3.1.3:2003 document contain?

The document contains the modified text of ITU-T Recommendation Q.731, clause 4, with an inserted Scope and Normative references section. It also includes a table that replaces several original references with ETSI documents used in the EN 300 356 framework.

Annex ZA adds an informative coding guide for compatibility information related to the generic number parameter. The document marks new or modified text with sidebars, underlining, and strike-out so readers can see what was changed from the ITU-T base text.

For implementers, the useful material is the service scope, the international-interface procedures, the reference substitutions, and the annex guidance on compatibility coding.
