SIST EN 300 356-1 V4.2.1:2004 is the Slovenian adoption of the ETSI European Standard for Integrated Services Digital Network (ISDN) signalling over Signalling System No.7 (SS7). It specifies ISDN User Part (ISUP) version 4 procedures for the international interface, with modified ITU-T Recommendations Q.761 to Q.764, for basic services on pan-European ISDN.

What does SIST EN 300 356-1 V4.2.1:2004 specify?

SIST EN 300 356-1 V4.2.1:2004 defines the ISUP procedures used to support basic bearer services and related supplementary services over SS7 for the international interface. It also states how the ETSI text modifies the ITU-T base recommendations, while keeping international interconnection behaviour compatible with ISUP version 4.

The document body replaces the Scope, References and Abbreviations clauses and then applies modifications to ITU-T Recommendations Q.761, Q.762, Q.763 and Q.764. Its annexes cover timers, national-use material, compatibility coding and bibliography.

What are the key requirements of SIST EN 300 356-1 V4.2.1:2004?

The standard focuses on how exchanges set up, carry and release ISDN calls across international SS7 interfaces, and on which extra parameters can travel with the call. In practice, implementers need to know when to send a parameter, when to pass it unchanged, and when to discard it at gateways.

1. International scope and national-use handling

The scope says the document applies to the international interconnection only, but it retains functions, formats, codes and exchange actions needed at originating and destination local exchanges. Items marked for national use are informative for the international interface, and items marked not required are not supported.

2. Supported call and signalling functions

Q.761 tables list the supported and non-supported functions and services for basic call handling, signalling procedures, congestion control, echo control, circuit blocking, reset and other exchange actions. For readers, this is the practical support matrix for what an ISUP implementation should handle.

3. Numbering and gateway control

Q.763 subclause 1.14 ties international number lengths to ITU-T Recommendation E.164. The text also says gateway exchanges must prevent extended national number lengths from leaking into the international network, which matters for interoperability.

4. Carrier selection information (CSI)

The text adds CSI as a national-use parameter and defines how it is handled in the originating exchange, intermediate exchanges, outgoing national gateways, incoming national gateways and international exchanges. This tells operators exactly where carrier selection is recorded and where it stops being carried.

5. Global Call Reference (GCR)

The standard adds GCR as a forward-direction parameter in the Initial Address Message (IAM). It is built from NetworkID, NodeID and CallReferenceID, so that a call can be uniquely identified and correlated across the network.

6. APM and service compatibility

Q.763 updates the Application Transport Mechanism (APM) and introduces structures for APM '98' and APM '2000' user applications, including segmentation and address fields. It also adds IN Service Compatibility handling, which supports interaction with Intelligent Network functions.

7. Annex-based procedures and coding

Annex A updates the ISDN User Part timer table, while Annex ZA gives coding guidance for compatibility information, access delivery, echo control, Temporary Alternative Routing (TAR), hop counter, collect call request and IN Service Compatibility Information. In practice, these annexes are the place to check the exact procedure and field coding.

What terms does SIST EN 300 356-1 V4.2.1:2004 define?

• Integrated Services Digital Network (ISDN) - the digital network environment for the services and signalling covered by the standard.
• Signalling System No.7 (SS7) - the signalling system used between exchanges.
• ISDN User Part (ISUP) - the SS7 protocol part that carries call control and related service signalling for ISDN.
• Application Transport Mechanism (APM) - the mechanism used to carry application information in segmented signalling data.
• Carrier Selection Information (CSI) - a parameter that shows how carrier selection was invoked.
• Global Call Reference (GCR) - a call identifier made from NetworkID, NodeID and CallReferenceID.
• Temporary Alternative Routing (TAR) - a network management indicator used in routing control.

Who uses SIST EN 300 356-1 V4.2.1:2004?

SIST EN 300 356-1 V4.2.1:2004 is used by public telecommunications operators, switch and gateway engineers, and SS7/ISUP equipment vendors. It is also used by interoperability and conformance test teams, especially when they need to check international ISDN call setup, supplementary services, carrier selection, and call correlation behaviour.

What changed in SIST EN 300 356-1 V4.2.1:2004 from the previous edition?

The document history lists V4.1.1 as the earlier publication. In V4.2.1, the text adds or updates handling for CSI, GCR, IN Service Compatibility, APM '2000' user applications, E.164-based number length control, and related gateway and timer rules.

Which standards are used with SIST EN 300 356-1 V4.2.1:2004?

• ITU-T Recommendation E.164 - gives the international numbering plan used for number-length limits.
• ETSI ETS 300 121 / ITU-T Recommendation Q.767 - provides the earlier ISUP interconnection reference.
• ETSI EN 300 356-2 to EN 300 356-20 - define the companion parts for supplementary services.
• ETSI EN 300 403-1 - provides the DSS1 signalling network layer reference used for Q.931.
• ETSI EN 300 485 - gives exceptions and clarifications to Q.850.
• ITU-T Recommendations X.121 and F.69 - provide data and telex numbering plan references.

What does the SIST EN 300 356-1 V4.2.1:2004 document contain?

The document contains modified message and parameter tables for ISUP basic services, including support rules for IAM, ACM, ANM, CPG, CON, APM, PRI and FAC. It also contains field layouts and coding for APM, CSI, GCR and related address fields, shown with figures in Q.763.

It further contains procedure text for gateway handling, routing, blocking, reset, TAR, hop counter, collect call and IN interactions. Annex ZA provides coding guidance for compatibility information and related transport cases, while Annex A gives the timer update used by the ISDN User Part.
