SIST EN 300 258 V1.3.1:2005

SIST EN 300 258 V1.3.1:2005 is the Slovenian adoption of ETSI EN 300 258 V1.3.1, a European telecommunications standard for the path replacement feature in a Private Integrated Services Network (PISN). It specifies the functional model and information flows for that additional network feature, and it is aimed at PISN service and signalling work.

What does SIST EN 300 258 V1.3.1:2005 specify?

SIST EN 300 258 V1.3.1:2005 specifies the Path replacement additional network feature (ANF) for PISN. In practice, it tells implementers how this feature is defined in the service model and how the related information flows are treated in the standard.

The document is an endorsement of ISO/IEC 13863, with ETSI modifications applied. The operative text shown in the document is the endorsement notice in Clause 3, which updates normative references and replaces selected references throughout the text.

What are the key requirements of SIST EN 300 258 V1.3.1:2005?

The standard is built around the PISN service model and the path replacement ANF. That matters because anyone implementing or specifying the feature needs to follow the same functional assumptions and signalling view.

1) Apply the endorsed ISO/IEC base with ETSI modifications

SIST EN 300 258 V1.3.1:2005 says that the elements of ISO/IEC 13863 (1998) apply, but with modifications. In practice, that means the international text is not used unchanged; implementers must read it together with the ETSI substitutions.

2) Use the updated normative references in Clause 3

SIST EN 300 258 V1.3.1:2005 inserts four normative references at the end of Clause 3:

• EN 300 189 for addressing
• EN 300 171 for control aspects of circuit-mode basic services
• ETS 300 475-1 for the PTN reference configuration
• ETS 300 387 for the method for specifying basic and supplementary services

These references matter because they provide the supporting rules the path replacement feature relies on.

3) Replace the original cross-references throughout the text

SIST EN 300 258 V1.3.1:2005 replaces references to ISO/IEC 11571, ISO/IEC 11574, ISO/IEC 11579-1, and CCITT Rec. I.130 with the ETSI documents named above. In practice, this keeps implementations aligned with the ETSI document set used by the PISN series.

4) Use the document wording “the present document”

SIST EN 300 258 V1.3.1:2005 replaces the phrase “this International Standard” with “the present document.” That is a drafting change, but it also signals that the ETSI version is the operative reference for users of this standard.

5) Read it as part of the PISN standards series

The foreword says the document belongs to a series of standards defining services and signalling protocols for PISN. The series uses ISDN concepts and follows the OSI framework, so readers should treat this as part of a wider signalling and service model, not as a stand-alone feature note.

6) Note the reference configuration context

Because the document points to PTN and PTNX terminology through ETS 300 475-1, users need to understand where the path replacement feature sits in the private network reference configuration. That helps when mapping the feature onto real network nodes and exchanges.

What terms does SIST EN 300 258 V1.3.1:2005 define?

• Private Integrated Services Network (PISN) - A private network environment for integrated services, used here as the overall framework for the feature.
• Additional Network Feature (ANF) - A network feature added on top of the basic service set; path replacement is one of these features.
• Integrated Services Digital Network (ISDN) - The concept base used by the PISN series for services and signalling.
• Open Systems Interconnection (OSI) - The architectural framework used by the series to organize standardization.
• Private Telecommunication Network (PTN) - The wider private network family referenced by the supporting ETSI documents.
• PTN exchange (PTNX) - A PTN exchange reference point used in the cited reference configuration.
• Path replacement - The feature covered by this standard, described through its functional model and information flows.

Who uses SIST EN 300 258 V1.3.1:2005?

This standard is used by telecom engineers, signalling specialists, and standards implementers working on PISN features. It is also relevant to equipment manufacturers and network planners who need a common definition of the path replacement ANF and its supporting references.

What changed in SIST EN 300 258 V1.3.1:2005 from the previous edition?

The document history lists earlier ETS 300 258 editions from 1993 and 1996, and the version published here is V1.3.1. The endorsement notice states the main changes applied to ISO/IEC 13863: added ETSI normative references, replaced several cross-references, and changed the wording “this International Standard” to “the present document.”

Which standards are used with SIST EN 300 258 V1.3.1:2005?

SIST EN 300 258 V1.3.1:2005 depends on four named supporting documents:

• EN 300 189 - provides PISN addressing
• EN 300 171 - covers control aspects of circuit-mode basic services
• ETS 300 475-1 - gives the PTN reference configuration for PTNXs
• ETS 300 387 - provides the method for specifying basic and supplementary services

The standard is also an endorsed version of ISO/IEC 13863 (1998), modified for ETSI use.

What does the SIST EN 300 258 V1.3.1:2005 document contain?

The document contains the ETSI foreword, IPR notice, transposition dates, and the endorsement notice for ISO/IEC 13863. Clause 3 sets out the normative references and the specific reference replacements applied throughout the text. It also includes document history showing the publication path from the earlier ETS 300 258 editions to V1.3.1.
