SIST EN 300 260 V1.3.1:2005

SIST EN 300 260 V1.3.1:2005 is the Slovenian adoption of ETSI EN 300 260 V1.3.1 for the Private Integrated Services Network (PISN) Call transfer supplementary service. It endorses ISO/IEC 13865 (2003) with ETSI modifications, so it gives the functional-model and information-flow specification for call transfer in PISN environments. It is written for telecom engineers, network vendors, and integrators who need a common service specification.

What does SIST EN 300 260 V1.3.1:2005 specify?

SIST EN 300 260 V1.3.1:2005 specifies the Call transfer supplementary service for PISN and presents it as part of a series of standards for services and signalling protocols. The foreword places the series in the context of Integrated Services Digital Network (ISDN) concepts and the Open Systems Interconnection (OSI) framework.

The document is an endorsement of ISO/IEC 13865 (2003) with modifications from ETSI. Its structure, as shown in the available text, is built around the foreword, the endorsement notice, Clause 3 on normative references, and the document history.

What are the key requirements of SIST EN 300 260 V1.3.1:2005?

SIST EN 300 260 V1.3.1:2005 mainly tells the reader how ISO/IEC 13865 (2003) is to be read in the ETSI/PISN context. The most important points are the service scope, the reference rules, and the reference substitutions that keep the document aligned with related ETSI standards.

• The service focus is call transfer in PISN.
  The standard specifies the Call transfer supplementary service, so implementers use it to define how an ongoing call is transferred within a private network.

• The service belongs to the PISN series.
  The foreword says the series defines services and signalling protocols for PISN, which matters because call transfer must fit the wider PISN service model.

• The series uses ISDN concepts and the OSI framework.
  This tells designers that the service description is built on established telecom and interoperability concepts rather than a standalone model.

• Clause 3 defines how references are treated.
  Specific references are fixed to the cited edition, while non-specific references always mean the latest version. In practice, this controls which companion documents must be used when implementing or testing the service.

• Clause 3 adds four normative references.
  The added references link call transfer to bearer services, PTN reference configurations, name identification supplementary services, and identification supplementary services. That matters because call transfer interacts with related network and identity functions.

• The text replaces several ISO/IEC references with ETSI equivalents.
  ISO/IEC 11574, ISO/IEC 11579-1, ISO/IEC 13864, and ISO/IEC 14136 are mapped to ETSI documents. This keeps cross-references inside the European standard family consistent.

• The wording “this International Standard” is replaced by “the present document.”
  This is a formal editorial change, but it matters for legal and technical reading because the ETSI text is the operative document in this edition.

What terms does SIST EN 300 260 V1.3.1:2005 define?

• Call transfer supplementary service - The PISN service covered by this standard, used to transfer an active call.
• Private Integrated Services Network (PISN) - The private network environment for which the service is specified.
• Integrated Services Digital Network (ISDN) - The telecom concept base used by the PISN standards series.
• Open Systems Interconnection (OSI) - The framework the series follows for structuring standardized communications.
• Private Telecommunication Network (PTN) - The broader network type referenced in the companion standards.
• PTN eXchanges (PTNXs) - The exchange nodes used in the PTN reference configuration.
• Intellectual Property Rights (IPR) - The rights area ETSI notes in connection with the standard and its possible essential patents.

Who uses SIST EN 300 260 V1.3.1:2005?

SIST EN 300 260 V1.3.1:2005 is used by people who design, integrate, test, or procure PISN and related telecom equipment. Network engineers use it to implement call transfer behavior consistently across systems.

Typical users include:

• PISN equipment vendors
• Telecom system integrators
• Test and interoperability labs
• Quality managers checking service conformance
• Buyers and technical specifiers in private telecommunication networks

What changed in SIST EN 300 260 V1.3.1:2005 from the previous edition?

The document history records earlier editions of ETS 300 260 in 1993 and 1996, followed by V1.3.1, which was approved in 2003 and published in January 2004. In this ETSI version, the ISO/IEC 13865 (2003) text is modified by adding Clause 3 normative references, replacing listed ISO/IEC references with ETSI references, and changing “this International Standard” to “the present document.”

Which standards are used with SIST EN 300 260 V1.3.1:2005?

Clause 3 also explains how to read references in the document: specific references stay tied to the cited edition, while non-specific references move to the latest version.

What does the SIST EN 300 260 V1.3.1:2005 document contain?

The document contains the foreword, the endorsement notice, Clause 3 on normative references, and the edited reference mapping used by the ETSI version. It also includes transposition dates, copyright and IPR notices, and the document history.

The technical content shown here is centered on standards linkage rather than on step-by-step procedures. In practice, that means the document is used together with the referenced PISN and PTN standards when defining, implementing, or checking call transfer behavior.
