SIST EN 301 914 V1.1.1:2005

SIST EN 301 914 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 914 V1.1.1, which endorses ISO/IEC 20161 (2001) with ETSI modifications. It specifies the functional profile for using QSIG at the C reference point between a PINX and an interconnecting network. In practice, it is for engineers and suppliers who need PINX interworking that can operate across equipment from different vendors and service providers in a PISN.

What does SIST EN 301 914 V1.1.1:2005 specify?

SIST EN 301 914 V1.1.1:2005 specifies how QSIG is used at the C reference point between a PINX and an interconnecting network. The foreword says the document belongs to the PISN signalling series and is intended to support interoperability across vendor and service-provider boundaries.

The document is an endorsement of ISO/IEC 20161, so its structure is built around the international text plus ETSI changes. The endorsement notice then adjusts clause 3, clause 4 and the wording used throughout the document.

What are the key requirements of SIST EN 301 914 V1.1.1:2005?

The standard’s main technical point is the functional profile for interconnecting PINX to VPN service centres so that QSIG-based interworking remains compatible across implementations. For users, that means the document is about aligning signaling behaviour and reference documents, not about a single product feature.

How references are treated

Clause 3 replaces the opening text on references. It distinguishes between specific references, which stay fixed to the cited edition, and non-specific references, which follow the latest version. In practice, implementers need to check whether a companion standard is locked to a dated edition or should be kept current.

Which companion standards are brought in

Clause 3 adds a set of normative references covering the surrounding PISN environment: reference configuration for PTNXs, addressing, static circuit-mode inter-PINX connections, 64 kbit/s circuit mode with 16 kbit/s sub-multiplexing, and the method for specifying basic and supplementary services. This matters because a conforming implementation depends on more than the QSIG profile alone.

Clause 3 also brings in signaling standards for services and features such as recall, clock synchronization, call transfer, advice of charge, call interception, transit counter, call priority interruption and protection, PUM call handling, single step call transfer, and wireless terminal call handling. In practice, these are the companion documents designers must use when a system supports those services.

What the ETSI wording changes

Clause 4 replaces two internal references in clause 4.1, changing ECMA identifiers to ETSI EN 300 172 and EN 300 239. The practical effect is that clause 4.1 points readers to ETSI documents rather than the older ECMA references.

The endorsement notice also replaces a number of in-text references throughout ISO/IEC 20161 with ETSI equivalents. This is important when tracing requirements, because the standard expects readers to follow the modified ETSI reference set.

What terms does SIST EN 301 914 V1.1.1:2005 define?

• Private Integrated Services Network (PISN) - the private network context addressed by the standard.
• Private Integrated services Network eXchange (PINX) - the exchange equipment that participates in the PISN interconnection.
• QSIG - the signaling system used at the C reference point in this standard.
• C reference point - the interface between a PINX and an interconnecting network.
• Additional Network Feature (ANF) - a named class of network feature cited in the companion references.
• Private User Mobility (PUM) - a named feature area covered by one of the referenced inter-exchange signaling protocols.
• Integrated Services Digital Network (ISDN) - the network concept framework referenced in the foreword.
• Open Systems Interconnection (OSI) - the standards framework mentioned for the series.

Who uses SIST EN 301 914 V1.1.1:2005?

SIST EN 301 914 V1.1.1:2005 is used by telecom equipment vendors, private network designers, and service providers working on PISN interworking. It is also relevant to test and quality teams that need to verify that a PINX interface follows the agreed QSIG profile.

In practice, buyers and integrators use it when they need interoperability between systems from different suppliers. Standards engineers use it to select the companion documents that define addressing, circuit-mode connections, and specific supplementary services.

What changed in SIST EN 301 914 V1.1.1:2005 from the previous edition?

SIST EN 301 914 V1.1.1:2005 endorses ISO/IEC 20161 (2001) with modifications. The stated changes are the replacement text in clause 3, the added normative references [26] to [40], the clause 4.1 reference updates, the reference substitutions throughout the document, and the wording change from “this International Standard” to “the present document”.

Which standards are used with SIST EN 301 914 V1.1.1:2005?

The document names these companion standards and what they contribute:

• ETSI ETS 300 475-1 - PTN reference configuration for PTNXs.
• ETSI EN 300 189 - addressing.
• ETSI EN 301 765 - functional requirements for static circuit-mode inter-PINX connections.
• ETSI EN 301 039 - mapping 64 kbit/s circuit mode connections with 16 kbit/s sub-multiplexing.
• ETSI ETS 300 387 - method for specifying basic and supplementary services.
• ETSI EN 301 257, EN 301 259, EN 300 261, EN 301 264, EN 301 265, EN 301 048, EN 301 656, EN 301 810, EN 301 919, and EN 301 827 - the inter-exchange signaling protocol standards for the specific services and features listed in the endorsement notice.

What does the SIST EN 301 914 V1.1.1:2005 document contain?

The document contains the ETSI foreword, IPR notice, national transposition dates, and the endorsement notice for ISO/IEC 20161. Its technical content is mainly the list of clause and reference substitutions that adapt the international standard for ETSI use.

It also contains a reference-replacement table that maps older ECMA and ISO/IEC references to the ETSI equivalents used in this version. For readers, that table is the practical guide to which standards must be consulted alongside the main text.
