Overview
SIST EN 300 356-2 V3.2.2:2003 is a European telecommunications standard specifying procedures for supplementary services in the Integrated Services Digital Network (ISDN) User Part (ISUP) using Signalling System No.7 (SS7) version 3 at the international interface. Building upon the ITU-T Recommendation Q.730 (1997), with modifications for European requirements, this standard defines additional generic procedures beyond basic call management. The purpose is to support various telecommunication supplementary services across public ISDN services in Europe, facilitating compatibility and interoperability between national and international telecommunication networks.
Key Topics
ISDN User Part (ISUP) and SS7
The standard addresses signalling needs for supplementary services using the ISUP protocol over the SS7 layer, ensuring robust and reliable communication between network exchanges internationally.Supplementary Services Support
It outlines generic procedures necessary for the activation, deactivation, and management of multiple supplementary services, such as call forwarding, call waiting, conference calls, and user-to-user signalling.International Interface Specificity
The document specifically applies to the international interconnection interface, detailing procedures required at originating and destination local exchanges as well as international gateway exchanges.Switching and Protocol Functions
Key functions and protocol elements are specified to ensure coordinated service delivery, including message formats, codes, and state handling compatible across different operator networks.Inclusion for National Use (Informative)
While the scope is international, formats and codes marked for national use are also presented for informational and harmonization purposes.
Applications
Implementing SIST EN 300 356-2 V3.2.2:2003 offers several practical benefits in modern telecommunications:
Enhanced Service Offerings
Service providers can implement a wide range of ISDN supplementary services-such as explicit call transfer, three-party calls, completion of calls to busy subscribers, connected line identification, and subaddressing-ensuring comprehensive feature sets for users.Interoperability Between Networks
The standardized procedures help enable seamless operation between different carriers’ equipment and across national borders, minimizing incompatibilities and service disruptions.Network Evolution and Testing
With defined procedures and references to test suites and conformance statements, network operators and equipment manufacturers can reliably test, deploy, and upgrade systems while ensuring compliance with pan-European norms.Regulatory and Procurement Compliance
Adhering to this standard ensures alignment with European regulatory requirements and simplifies procurement and integration processes in multi-vendor, multinational deployments.

ETSIEN 300 356-2 V3.2.2 (1998-08)5Global modifications to ITU-T Recommendation Q.730Replace the two clauses "Scope" and "References" with the following two clauses (Scope and Normative references):ScopeThis second part of EN 300 356 specifies procedures that are common to multiple supplementary services defined forthe pan-European Integrated Services Digital Network (ISDN) as provided by the European public telecommunicationsoperators by means of the Signalling System No.7 protocol for the ISDN User Part (ISUP). The present documentidentifies the protocol procedures and switching functions needed to support telecommunication services (seeCCITT Recommendation I.130 [1]).The present document does not specify the additional protocol requirements where the service is provided to the user viaa telecommunications network that is not an ISDN.The present document does not specify the additional protocol requirements for the national signalling interface.Although the present document applies only to the international interconnection, the specification of functions, formatsand codes of messages and signals, and actions performed at originating and destination local exchanges are retained.Formats, codes and procedures marked for national use are included for informative purposes for the internationalinterface specification. If these items so marked are supported within a national network and operator's network, then itis proposed that they shall be supported in this manner.Items in the present document marked "Not Required" are not required to be supported.NOTE:In the case where a national signalling system behaves differently, the international gateway exchange isto support both the concerned national and international network.ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, subsequent revisions do apply.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]CCITT Recommendation I.130 (1988): "Method for the characterization of telecommunicationservices supported by an ISDN and network capabilities of an ISDN".[2]ETS 300 121 (1992): "Integrated Services Digital Network (ISDN); Application of the ISDN UserPart (ISUP) of CCITT Signalling System No.7 for international ISDN interconnections (ISUPversion 1)".[3]EN 300 356-1: "Integrated Services Digital Network (ISDN); Signalling System No.7; ISDN UserPart (ISUP) version 3 for the international interface; Part 1: Basic services[ITU-T Recommendations Q.761 to Q.764 (1997), modified]".SIST EN 300 356-2 V3.2.2:2003
