SIST EN 300 363 V1.3.1:2005

SIST EN 300 363 V1.3.1:2005 is the Slovenian adoption of ETSI EN 300 363 V1.3.1. It specifies the Private Integrated Services Network (PISN) Do Not Disturb (DND) and Do Not Disturb Override supplementary services at the specification, functional model, and information-flow level for PISN standards work.

What does SIST EN 300 363 V1.3.1:2005 specify?

SIST EN 300 363 V1.3.1:2005 endorses ISO/IEC 14842 (1996) for PISN, with ETSI modifications. The standard is version 2 of ETS 300 363 and applies the ISO stage 1 and stage 2 Do not disturb and Do not disturb override supplementary services.

The endorsement notice shows how the ISO/IEC text is adapted:

• clause 3 is replaced to define how references are treated
• new normative references are inserted
• several ISO/IEC references are replaced by ETSI PISN documents
• the phrase “this International Standard” is replaced by “the present document”

In practice, the document is meant for PISN service specification and signalling work, where the wording and cross-references must match the ETSI reference set used by the rest of the PISN series.

What are the key requirements of SIST EN 300 363 V1.3.1:2005?

SIST EN 300 363 V1.3.1:2005 mainly sets the service scope, the reference rules, and the companion standards that form the technical basis of the service description.

• The document specifies the DND and DND override supplementary services. For users of the standard, this is the service definition to follow when describing how these supplementary services are represented in a PISN.
• The series is built on Integrated Services Digital Network (ISDN) concepts and conforms to the Open Systems Interconnection (OSI) framework. This matters because the service model is aligned with widely used telecom and information-architecture concepts.
• Clause 3 defines reference handling. Specific references stay fixed to the cited edition, while non-specific references use the latest version. That is important when checking which companion standard applies in a design or review.
• Clause 3 inserts ETSI normative references [14] to [23]. These references tie the document to the matching ETSI PISN standards for addressing, bearer services, reference configuration, path replacement, name identification, call transfer, call completion, diversion, identification, and call offer.
• The document replaces earlier ISO/IEC reference names throughout the text with the ETSI equivalents. In practice, this keeps the service definition consistent with the ETSI PISN family rather than the original ISO/IEC citations.
• The document uses the term “the present document” instead of “this International Standard”. That wording is part of the endorsement and tells readers they are working with the ETSI-adopted version.

What terms does SIST EN 300 363 V1.3.1:2005 define?

SIST EN 300 363 V1.3.1:2005 uses the common PISN and telecom terms that frame the service description.

• PISN - Private Integrated Services Network, the network type covered by the standard.
• DND - Do Not Disturb, the supplementary service named in the title.
• Do Not Disturb Override - the companion supplementary service that bypasses DND.
• ISDN - Integrated Services Digital Network, the concept base used by the PISN series.
• OSI - Open Systems Interconnection, the framework the series conforms to.
• Supplementary service - an add-on service defined within the PISN service model.
• stage 1 - the service-level view used in the endorsed ISO material.
• stage 2 - the functional and information-flow view used in the endorsed ISO material.

Who uses SIST EN 300 363 V1.3.1:2005?

SIST EN 300 363 V1.3.1:2005 is used by people working on PISN service definition and signalling. The foreword says the document belongs to a series of standards for PISN services and signalling protocols, produced by ECMA on behalf of its members and ETSI members.

Typical users include standards engineers, telecom network architects, equipment vendors, and interoperability or conformance teams. It is also relevant to national standards bodies and organizations transposing ETSI telecom standards into national collections.

What changed in SIST EN 300 363 V1.3.1:2005 from the previous edition?

SIST EN 300 363 V1.3.1:2005 is identified as version 2 of ETS 300 363, and the history shows an earlier ETS 300 363 V1.2.1 publication. This edition endorses ISO/IEC 14842 (1996) and updates the document to the ETSI EN 300 363 V1.3.1 form.

The endorsement notice states three practical changes:

• clause 3 is rewritten for reference handling
• new ETSI references are added
• the ISO/IEC reference names and the phrase “this International Standard” are replaced throughout the text

Which standards are used with SIST EN 300 363 V1.3.1:2005?

SIST EN 300 363 V1.3.1:2005 relies on the following companion standards named in clause 3. They provide the related PISN functions that the DND services build on.

What does the SIST EN 300 363 V1.3.1:2005 document contain?

SIST EN 300 363 V1.3.1:2005 contains the ETSI foreword, the endorsement notice, the clause 3 reference updates, and the publication history. It also includes the table that maps ISO/IEC references to the ETSI PISN documents used in this version.

For a reader, that means the document is an endorsed and adapted service specification rather than a standalone tutorial. Its main value is the controlled wording, the reference mapping, and the link to the companion PISN standards needed for service description and signalling alignment.
