SIST ETS 300 260 E2:2005

SIST ETS 300 260 E2:2005 is the Slovenian adoption of ETS 300 260 Edition 2, published by SIST. It specifies the Call transfer supplementary service (SS-CT) for Private Integrated Services Network (PISN), including the functional models and information flows used to support call transfer across PISN basic services.

What does SIST ETS 300 260 E2:2005 specify?

SIST ETS 300 260 E2:2005 specifies SS-CT for use with various basic services supported by PISN. In practice, it is the ETSI version of ISO/IEC 13865 with agreed modifications, so implementers follow the ETS text rather than the unmodified international text.

The standard belongs to the PISN service and signalling series. The foreword says the series uses Integrated Services Digital Network (ISDN) concepts and fits the Open Systems Interconnection (OSI) framework, which matters if you are aligning PISN behaviour with broader telecom and network design rules.

The document is organized around:

• clause 3, which sets out normative references
• service-element tables and explanatory text in subclauses 7.2.1.2, 7.2.1.3, 7.2.1.4 and 7.2.1.6
• service-element content in subclause 8.2.1.5.2

What are the key requirements of SIST ETS 300 260 E2:2005?

SIST ETS 300 260 E2:2005 requires the call transfer specification to be read with ETSI reference substitutions and with the service-element updates listed in the endorsement notice. For an engineer, this means the call transfer flows are not just a generic ISO/IEC description - the ETSI references and modified tables are part of the applicable specification.

Clause 3: normative references

Clause 3 replaces the opening paragraph on references and states how dated and undated references are applied. It also adds several ETSI references at the end of the clause, so a reader has to use the specified PISN and PTN documents when interpreting the service.

Service-element updates in the call transfer tables

In subclause 7.2.1.2, table 2 adds Connected Number (CN) and Destination Category (DC) before End Designation (ED). This tells implementers that the call transfer exchange can carry those elements in that part of the procedure.

In subclause 7.2.1.3, table 3 adds Connected Subaddress (CS) and DC. For practice, that means the service information can include both the connected subaddress and the destination category in that flow.

In subclause 7.2.1.4, table 4 adds CS and DC before Terminal Details Request (TDR). The later sentence is also updated to refer to DC and CH, which helps readers map the text to the revised table.

Additional updates in the later tables

In subclause 7.2.1.6, table 6 adds CN and DC, and the following sentence is updated to refer to CN, CH and DC. This is important where the service description depends on which elements are present in the exchange.

In subclause 8.2.1.5.2, table 10 adds CN and DC in the service-element list, and the accompanying sentence is updated in the same way. This links the stage 2 information flow description to the ETSI-modified service elements.

What terms does SIST ETS 300 260 E2:2005 define?

• Private Integrated Services Network (PISN) - the network type covered by the standard, used for integrated voice and related services in a private network environment.
• Call transfer supplementary service (SS-CT) - the supplementary service that lets a call be transferred within the PISN service model.
• Integrated Services Digital Network (ISDN) - the concept family the series uses as a basis for its service and signalling approach.
• Open Systems Interconnection (OSI) - the framework the series conforms to when describing services and information flows.
• Connected Number (CN) - a service element that appears in the call transfer tables where connected party information is carried.
• Destination Category (DC) - a service element added to several call transfer tables to identify the destination category in the information flow.
• Connected Subaddress (CS) - a service element used where subaddress information is part of the call transfer exchange.
• Terminal Details Request (TDR) - a service element listed in table 4 for requesting terminal details.

Who uses SIST ETS 300 260 E2:2005?

SIST ETS 300 260 E2:2005 is used by telecommunications engineers, PISN equipment vendors, network planners, and interoperability test teams. It is also relevant to quality and conformance teams that need to check whether a private network implementation handles SS-CT with the ETSI-modified service elements. The ICS classification points to telephone networks, so the main application area is telecom signalling and service specification.

What changed in SIST ETS 300 260 E2:2005 from the previous edition?

SIST ETS 300 260 E2:2005 replaces the first edition with a second edition that endorses ISO/IEC 13865 and applies agreed modifications. The stated changes include the updated normative references and the added or revised service-element rows in tables 2, 3, 4, 6 and 10, together with the corresponding wording changes in subclauses 7 and 8.

Which standards are used with SIST ETS 300 260 E2:2005?

• ETS 300 171 - provides the control aspects of circuit mode basic services for PTN.
• prETS 300 173 - covers identification supplementary services for PISN.
• prETS 300 237 - covers name identification supplementary services for PISN.
• ETS 300 387 - provides the method for specifying basic and supplementary services.
• ETS 300 475-1 - gives the reference configuration for PTN eXchanges (PTNX).

What does the SIST ETS 300 260 E2:2005 document contain?

The document contains the ETS endorsement notice, transposition dates, and a history note showing the first and second edition. It also includes the modified normative references and the specific textual replacements applied throughout ISO/IEC 13865. The substantive technical content is concentrated in the service-element tables in clauses 7 and 8, where the standard lists which elements apply to the call transfer supplementary service. Those tables are used to describe the information flows and the data items that implementations need to carry or recognize.
