SIST EN 300 356-5 V3.1.3:2003 is the Slovenian adoption of ETSI EN 300 356-5 V3.1.3, published by SIST. It specifies the stage 3 protocol procedures and switching functions for the Connected Line Identification Presentation (COLP) supplementary service on the ISDN User Part (ISUP) version 3 for the international interface. In practice, it is for telecommunications operators and network implementers who need COLP support across ISDN/SS7 interconnections.

What does SIST EN 300 356-5 V3.1.3:2003 specify?

SIST EN 300 356-5 V3.1.3:2003 specifies the international-interface, stage 3 description of COLP for the pan-European Integrated Services Digital Network (ISDN). Stage 3 is the signalling and switching level, so the document is about how the service is implemented in the network, not just how it is experienced by the user.

The document is built around clause 5 of ITU-T Recommendation Q.731 (1993), with ETSI modifications. It includes a scope and normative references at the start of the clause, and one informative annex.

What are the key requirements of SIST EN 300 356-5 V3.1.3:2003?

SIST EN 300 356-5 V3.1.3:2003 sets the signalling procedures needed to support COLP over the Signalling System No.7 (SS7) ISUP interface. The practical result is that implementers must handle the call-control signalling and switching behaviour that lets the calling party receive the connected party’s identification.

Service scope and limits

The COLP supplementary service gives the calling party the possibility to receive identification of the connected party. The document says this service applies to all telecommunication services, so it is not limited to one call type.

The document is limited to the ISDN international interconnection. It does not specify extra protocol requirements when the service is offered through a network that is not an ISDN, and it does not specify the national signalling interface. For a buyer or engineer, that means the standard is aimed at the international gateway and the associated ISUP behaviour, not every national variant.

Signalling and switching behaviour

The standard retains the specification of functions, formats, codes, and actions at originating and destination local exchanges, even though it applies only to the international interface. It also keeps items marked for national use, but only for informative purposes in the international specification.

Where a national signalling system behaves differently, the international gateway exchange is expected to support both the national and the international behaviour. In practice, this matters when a network must interwork cleanly with both local national signalling and the international ISUP path.

Annex ZA and compatibility coding

Annex ZA gives recommended coding for the compatibility information associated with the generic number parameter. This is the part that implementers use when they need the parameter to pass through exchanges with the intended handling of transit, release, notification, discarding, and broadband or narrowband interworking indicators.

What terms does SIST EN 300 356-5 V3.1.3:2003 define?

• Integrated Services Digital Network (ISDN) - the digital network environment for which the service is specified.
• Signalling System No.7 (SS7) - the signalling system used to carry the inter-network control information.
• ISDN User Part (ISUP) - the SS7 user part used for ISDN call control and related signalling.
• Connected Line Identification Presentation (COLP) - the supplementary service that presents the connected party’s identity to the calling party.
• Calling party - the party that initiates the call and receives the connected line identification.
• Connected party - the party whose identification is presented through COLP.
• International interface - the interconnection point addressed by this standard for cross-network signalling.
• Stage 3 - the specification level that defines protocol procedures and switching functions.

Who uses SIST EN 300 356-5 V3.1.3:2003?

SIST EN 300 356-5 V3.1.3:2003 is used by European public telecommunications operators, switch and signalling equipment implementers, and network engineers working on ISDN interconnections. It is also relevant to test and conformance teams that need to verify COLP behaviour in ISUP-based networks. Buyers and quality managers use it to check whether a product or network element supports the required international COLP signalling.

What changed in SIST EN 300 356-5 V3.1.3:2003 from the previous edition?

SIST EN 300 356-5 V3.1.3:2003 is the EN version of ITU-T Recommendation Q.731, clause 5 (1993), approved with ETSI modifications. The modifications add a scope and normative references at the start of clause 5, and they replace several references throughout the text with ETSI/EN documents used for ISDN, ISUP, and DSS1 interworking.

Which standards are used with SIST EN 300 356-5 V3.1.3:2003?

The document cites these normative references and companion parts:

• CCITT Recommendation I.130 - the three-stage method for characterizing telecommunication services in ISDN.
• ETS 300 094 - the COLP service description.
• ETS 300 096 - the functional capabilities and information flows for COLP and COLR.
• ETS 300 097-1 - the DSS1 protocol specification for COLP.
• ETS 300 121 - ISUP version 1 for international ISDN interconnections.
• EN 300 356-1 - ISUP version 3 basic services.
• EN 300 356-2 - ISUP version 3 ISDN supplementary services.
• EN 300 403-1 - the DSS1 signalling network layer for circuit-mode basic call control.

These references supply the service model, protocol background, and companion ISUP/DSS1 material that this part depends on.

What does the SIST EN 300 356-5 V3.1.3:2003 document contain?

SIST EN 300 356-5 V3.1.3:2003 contains the modified text of clause 5 from ITU-T Recommendation Q.731, including the inserted scope and normative references. It also contains a replacement table that maps the original recommendation references to the ETSI and EN documents used in the European implementation.

The document includes an informative annex on compatibility information coding for the generic number parameter. It also carries the ETSI foreword, IPR notice, and publication history, which help readers understand the document’s status and lineage.
