SIST EN 300 171 V1.3.1:2005

SIST EN 300 171 V1.3.1:2005 is the Slovenian adoption of ETSI EN 300 171 V1.3.1 for Private Integrated Services Network (PISN) circuit-mode 64 kbit/s bearer services. It specifies the service description and control aspects, including functional capabilities and information flows, for standardized bearer services that a PISN may support. The document endorses ISO/IEC 11574 (2000) with ETSI modifications, so it is mainly used to align PISN implementations and related references.

What does SIST EN 300 171 V1.3.1:2005 specify?

SIST EN 300 171 V1.3.1:2005 specifies how standardized circuit-mode 64 kbit/s bearer services are described and controlled in a PISN. It is an endorsement document, so its main role is to apply ISO/IEC 11574 (2000) with a small set of ETSI changes.

The document sits in a series of standards for PISN services and signalling protocols. The foreword places that series in the context of ISDN concepts and the OSI framework, which helps readers understand the network model behind the bearer service.

The visible structure is:

• Foreword - series context and technical background
• Endorsement notice - states that ISO/IEC 11574 applies with modifications
• Clause 3 - normative reference updates and reference replacements
• History - publication and approval milestones

What are the key requirements of SIST EN 300 171 V1.3.1:2005?

SIST EN 300 171 V1.3.1:2005 mainly updates the reference framework around ISO/IEC 11574 (2000). In practice, that means implementers and reviewers must use the ETSI replacements and the stated rules for how references behave.

• Clause 3 replaces the opening paragraph on normative references. The document states that specific references are fixed to the cited edition, while non-specific references use the latest version. In practice, this tells users whether they must lock to a named edition or track updates.
• Clause 3 adds two normative references. EN 300 189 and ETS 300 475-1 are inserted as references [13] and [14]. This matters because they become part of the standard’s required context.
• ISO/IEC 11571 is replaced by EN 300 189 throughout the text. EN 300 189 is the PISN addressing reference, so this keeps the service description tied to the ETSI addressing standard.
• ISO/IEC 11579-1 is replaced by ETS 300 475-1 throughout the text. ETS 300 475-1 covers the PTN reference configuration for PTNXs, so the document points implementers to the ETSI reference model for network exchanges.
• “this International Standard” is replaced by “the present document”. This is an editorial but important wording change, because it aligns the text with ETSI/EN style and avoids confusion about the referenced document.
• The foreword states the technical scope of the series. The standard describes service description and control aspects, including functional capabilities and information flows, for standardized circuit-mode bearer services supported by a PISN. That tells a reader what kind of service behavior the standard is meant to cover.

What terms does SIST EN 300 171 V1.3.1:2005 define?

SIST EN 300 171 V1.3.1:2005 uses several key abbreviations and network terms that shape its scope.

• PISN - Private Integrated Services Network, the network type for which the bearer services are specified.
• ISDN - Integrated Services Digital Network, the concept base referenced by the PISN series.
• OSI - Open Systems Interconnection, the framework the series conforms to.
• PTN - Private Telecommunication Network, the broader network family referenced in the modified documents.
• PTNXs - PTN eXchanges, the exchange type named in ETS 300 475-1.
• IPRs - Intellectual Property Rights, mentioned in the notice on potentially essential rights.
• OAP - One-step Approval Procedure, the approval route recorded in the document history.

Who uses SIST EN 300 171 V1.3.1:2005?

SIST EN 300 171 V1.3.1:2005 is used by people working on PISN services and signalling, especially telecommunications engineers, network designers, equipment vendors, and standards or compliance staff. It is also relevant to buyers and quality managers who need to check which bearer-service and reference documents apply to a PISN implementation.

These users rely on the standard when they need a common description of circuit-mode 64 kbit/s bearer services and when they must align addressing and network-reference documents across an implementation.

What changed in SIST EN 300 171 V1.3.1:2005 from the previous edition?

The document history records the progression from the original publication as ETS 300 171 in December 1992, through V1.2.1 in September 1997, to V1.3.1 after the One-step Approval Procedure in February 2003 and publication in June 2003. The page also shows the Slovenian adoption date of 01 March 2005.

Which standards are used with SIST EN 300 171 V1.3.1:2005?

SIST EN 300 171 V1.3.1:2005 is based on ISO/IEC 11574 (2000), which it endorses with modifications. The text also brings in two companion ETSI references:

• EN 300 189 - provides the PISN addressing reference used in place of ISO/IEC 11571.
• ETS 300 475-1 - provides the PTN reference configuration for PTNXs used in place of ISO/IEC 11579-1.

These references matter because they connect the bearer-service description to the numbering and reference-configuration rules needed to implement or assess a PISN.

What does the SIST EN 300 171 V1.3.1:2005 document contain?

SIST EN 300 171 V1.3.1:2005 contains a short endorsement notice rather than a full service protocol specification. It includes the foreword, the clause 3 modifications, a reference-replacement table, and a history section.

The table in clause 3 shows which ISO/IEC references are replaced by which ETSI documents. The rest of the document records publication and approval milestones and gives the context for the standard’s place in the PISN series.
