SIST ETS 300 258 E2:2005

SIST ETS 300 258 E2:2005 is the Slovenian standard identical to ETS 300 258 Edition 2, a European Telecommunication Standard from ETSI/ECMA for Private Integrated Services Networks (PISN). It specifies the Path Replacement additional network feature (ANF-PR), which applies to various basic services in PISN and is written for people designing, implementing, or assessing PISN services and signalling.

What does SIST ETS 300 258 E2:2005 specify?

SIST ETS 300 258 E2:2005 specifies the Path Replacement additional network feature (ANF-PR) for PISN. In practice, it tells readers how this feature is treated within the PISN service and signalling framework, so it is relevant when a network must support path replacement across basic services.

The foreword places SIST ETS 300 258 E2:2005 in a series of standards for PISN services and signalling protocols. That series uses Integrated Services Digital Network (ISDN) concepts and follows the Open Systems Interconnection (OSI) framework, which helps implementers align the feature with broader telecom and interconnection models.

What are the key requirements of SIST ETS 300 258 E2:2005?

SIST ETS 300 258 E2:2005 is primarily an endorsed and modified text of ISO/IEC 13863 (1995). The key practical point is that implementers are expected to use the international text together with ETSI adjustments, especially the updated references and terminology substitutions listed in clause 3.

Clause 3 sets the reference framework

Clause 3 adds normative references that support the feature specification:

• ETS 300 171 for control aspects of circuit mode basic services
• ETS 300 189 for addressing
• ETS 300 387 for the method used to specify basic and supplementary services
• ETS 300 475-1 for the reference configuration of PTNX

For a reader, this means the feature is not read in isolation. It relies on established PTN documents for numbering, service description, and network reference configuration.

Clause 3 also updates cross-references in the base text

Throughout ISO/IEC 13863, the ETS replaces several references with ETS equivalents:

• CCITT Recommendation I.130 becomes ETS 300 387
• ISO/IEC 11571 becomes ETS 300 189
• ISO/IEC 11574 becomes ETS 300 171
• ISO/IEC 11579-1 becomes ETS 300 475-1

This matters because it shows which ETS documents should be used when applying the feature in a PISN environment.

Clause 3 changes the document’s terminology

The text replaces the term “International Standard” with “ETS” throughout ISO/IEC 13863. For users, that means the feature specification is being presented as an ETS rather than as a standalone international publication, while keeping the underlying technical content aligned.

The second edition is an endorsed version

The foreword says the first edition was a standalone specification, while this second edition endorses ISO/IEC 13863 published later. In practice, readers should treat this edition as the ETS version of that international feature specification.

What terms does SIST ETS 300 258 E2:2005 define?

SIST ETS 300 258 E2:2005 uses a small set of core telecom terms that are central to the document.

• Private Integrated Services Network (PISN) - a private network environment for integrated services, which is the main setting for the feature.
• Path Replacement additional network feature (ANF-PR) - the feature specified by the standard, used to replace a path within the network.
• Integrated Services Digital Network (ISDN) - the concepts used as a basis for the PISN standards series.
• Open Systems Interconnection (OSI) - the framework the series follows for standard structure and interoperability.
• Private Telecommunication Network (PTN) - the wider family of private network standards referenced by the document.
• PTNX - the PTN exchange reference configuration named in ETS 300 475-1.
• ETSI - the standards body whose endorsed version forms this ETS.

Who uses SIST ETS 300 258 E2:2005?

SIST ETS 300 258 E2:2005 is used by telecom engineers, signalling specialists, equipment vendors, and network planners working with PISN. It is also relevant to quality and compliance teams that need to check whether a private network implementation follows the ETSI version of the path replacement feature.

The document is especially relevant in telephone and telecom networks, where addressing, basic service control, and reference configurations must be consistent across implementations.

What changed in SIST ETS 300 258 E2:2005 from the previous edition?

SIST ETS 300 258 E2:2005 is the second edition. The foreword states that the previous edition was a standalone specification, and this edition endorses ISO/IEC 13863 (1995) with agreed modifications.

The changes stated in the document are the updated normative references, the replacement of certain cross-references with ETS documents, and the replacement of the term “International Standard” by “ETS”.

Which standards are used with SIST ETS 300 258 E2:2005?

SIST ETS 300 258 E2:2005 names these companion standards and references:

• ISO/IEC 13863 (1995) - the international text that this ETS endorses with modifications
• ETS 300 171 - control aspects of circuit mode basic services
• ETS 300 189 - addressing
• ETS 300 387 - method for the specification of basic and supplementary services
• ETS 300 475-1 - reference configuration for PTNX

These references provide the supporting PTN service, addressing, and configuration framework needed to apply ANF-PR.

What does the SIST ETS 300 258 E2:2005 document contain?

SIST ETS 300 258 E2:2005 contains the foreword, the endorsement notice, and clause 3 on normative references and text substitutions. The document also identifies how the ETS differs from the ISO/IEC text by listing modified references and terminology.

The front matter includes publication and transposition information, while the body identifies the feature and its relationship to the PISN standards series. The document uses marked changes, such as sidebars and underlining/strike-out, to show where the ETS text differs from the endorsed international standard.
