SIST EN 300 356-6 V4.1.2:2004 is the Slovenian adoption of ETSI EN 300 356-6 Version 4.1.2. It specifies the stage 3 protocol procedures and switching functions for the Connected Line Identification Restriction (COLR) supplementary service in Integrated Services Digital Network (ISDN) Signalling System No. 7 (SS7) ISDN User Part (ISUP) version 4 for the international interface.

What does SIST EN 300 356-6 V4.1.2:2004 specify?

SIST EN 300 356-6 V4.1.2:2004 specifies the stage 3 part of the COLR supplementary service for pan-European ISDN carried over SS7 ISUP. In practice, that means it describes the signalling behaviour and exchange functions needed to support the service between networks.

The document is built as an endorsement of ITU-T Recommendation Q.731, clause 6, with a Scope and References section inserted at the start of that clause. It focuses on the international interconnection context and retains the functions, formats, codes, and actions that apply at originating and destination local exchanges.

The scope also states what the document does not cover:

• additional protocol requirements when the service is provided through a non-ISDN telecommunications network
• additional protocol requirements for the national signalling interface

What are the key requirements of SIST EN 300 356-6 V4.1.2:2004?

SIST EN 300 356-6 V4.1.2:2004 defines the protocol side of COLR, not the user service description. The most important points are the service behaviour, the international-interface limits, and how national-use items are treated.

Stage 3 focus

The standard covers stage 3 as defined by ITU-T Recommendation I.130. Stage 3 is the level that identifies the signalling system protocols and switching functions needed to implement the service. For a reader, this means the document is aimed at network behaviour and message handling, not at user-facing service wording.

COLR service purpose

COLR lets the connected party prevent presentation of its ISDN number to the calling party. In operational terms, this is the signalling support needed when a network must withhold the connected line number.

Applicable service range

The document says COLR applies to all telecommunication services. That makes the signalling rules relevant across service types that use the ISDN/SS7 environment.

International interface only

The standard applies only to the international interconnection. It keeps the signalling functions, message formats, codes, and exchange actions that are needed at the international boundary, while excluding extra national-interface requirements.

National-use items

Formats, codes, and procedures marked for national use are included for informative purposes in the international interface specification. If a network or operator supports those items in the national network, the document proposes that they be supported in that same way. For implementers, this matters when aligning national deployment with the international scheme.

Gateway behaviour

If a national signalling system behaves differently, the international gateway exchange is expected to support both the national and the international network concerned. This is the practical interoperability rule that helps avoid service breakage at the border.

Reference substitution table

The clause replaces several references used in ITU-T Recommendation Q.731, clause 6, with ETSI documents such as ETS 300 095, ETS 300 096, EN 300 356-1, EN 300 356-2, and EN 300 403-1. This tells the reader which ETSI specifications define the related service, ISUP, and DSS1 behaviour.

What terms does SIST EN 300 356-6 V4.1.2:2004 define?

• Integrated Services Digital Network (ISDN) - the digital telecommunications environment in which the service is defined.
• Signalling System No. 7 (SS7) - the signalling system used to carry the ISUP procedures.
• ISDN User Part (ISUP) - the SS7 part that carries ISDN call-control and supplementary-service signalling.
• Connected Line Identification Restriction (COLR) - the supplementary service that prevents presentation of the connected party’s ISDN number.
• Stage 3 - the level of service description that specifies signalling protocols and switching functions.
• International interface - the interconnection boundary between networks that this standard addresses.

Who uses SIST EN 300 356-6 V4.1.2:2004?

SIST EN 300 356-6 V4.1.2:2004 is used by telecommunications operators, network engineers, switch vendors, and protocol implementers working with ISDN and SS7 interconnection. It is also relevant to conformance and interoperability teams that need to verify COLR behaviour at international gateways and local exchanges.

What changed in SIST EN 300 356-6 V4.1.2:2004 from the previous edition?

The document history records earlier publications as ETS 300 356-6 V3.1.3, V4.1.1, and the current V4.1.2 publication. The history section shows the edition trail from 1995 through 2001.

What does the SIST EN 300 356-6 V4.1.2:2004 document contain?

The document contains a foreword that places it within the ETSI ISUP version 4 multi-part series, including the related parts for basic services and other supplementary services. It also contains the endorsement notice, the inserted Scope and References text for ITU-T Recommendation Q.731 clause 6, and a table that maps replaced references to ETSI documents.

It further includes the national transposition dates, IPR notice, copyright notice, and publication history. The reference table is the main technical navigation aid because it shows which ETSI texts replace the original ITU-T references used in the modified clause.
