(Main)Private Integrated Services Network (PISN); Inter-exchange signalling protocol; Wireless terminal call handling Additional Network Feature (ANF) [ISO/IEC 15431 (2003), modified]
- Abstract
ANF-WTMI is a feature that directs incoming calls to a WTMI user within the PISN regardless of the WTMI user's geographical location within the PISN, provided that the WTMI user's location is known. Roaming outside the PISN is outside the scope of this edition of this standard. ANF-WTMO permits the PISN to process call requests from a WTMO user at the Home mocation, if required.

SIST EN 301 827 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 827 V1.1.1, a European telecommunications standard for Private Integrated Services Network (PISN) inter-exchange signalling. It specifies the signalling protocol at the Q reference point for the Wireless Terminal Call Handling Additional Network Feature (ANF), supporting ANF-WTMI and ANF-WTMO in PISN environments. The document is based on ISO/IEC 15431 (2003) with ETSI modifications.
What does SIST EN 301 827 V1.1.1:2005 specify?
SIST EN 301 827 V1.1.1:2005 specifies how a PISN handles wireless terminal call handling through signalling between exchanges. Its scope is limited to operation inside the PISN, with roaming outside the PISN left out of this edition.
The document ties the feature to two cases:
- ANF-WTMI directs incoming calls to a WTMI user within the PISN when the user's location is known.
- ANF-WTMO lets the PISN process call requests from a WTMO user at the Home location when required.
The standard is organized as an endorsement of ISO/IEC 15431 (2003). The visible text shows the foreword, an endorsement notice, clause 3 on normative references, a replacement table for references used throughout the international standard, and a document history.
What are the key requirements of SIST EN 301 827 V1.1.1:2005?
SIST EN 301 827 V1.1.1:2005 defines the signalling protocol for the wireless terminal call handling ANF at the Q reference point. In practice, implementers need to support the signalling behavior that lets the network route and process calls for wireless terminal users according to their location.
- WTMI support inside the PISN - incoming calls are directed to the user when the location is known. This matters because the network must have location information available before it can route the call correctly.
- WTMO handling at the Home location - the PISN may process call requests from a WTMO user at the Home location when required. This matters for systems that treat the home location as the point where the network applies special call handling.
- Roaming outside the PISN is excluded - the scope limits this edition to the PISN itself. That means network design and conformance work should not assume support for external roaming scenarios.
- PSS1 / QSIG context - the protocol forms part of the PSS1 protocol, informally known as QSIG. This matters because the standard is intended for use with a defined family of PISN signalling protocols.
- ISDN and OSI basis - the series uses Integrated Services Digital Network (ISDN) concepts and conforms to the Open Systems Interconnection (OSI) framework. This places the feature within the wider telecommunications signalling model used by the series.
- Fixed normative references - clause 3 states that specific references do not follow later revisions. In practice, implementers and testers must use the named companion standards as referenced in this document.
- Reference replacements throughout the text - ISO/IEC references are replaced with ETSI EN and ETS references. This matters when reading the document together with companion PISN standards, because the cited documents are the ETSI editions listed here.
- Terminology replacement - the phrase “this International Standard” is replaced by “the present document”. This keeps the endorsement text aligned with ETSI wording.
What terms does SIST EN 301 827 V1.1.1:2005 define?
- PISN (Private Integrated Services Network) - a private telecommunications network environment for integrated services, which is the system in which the signalling applies.
- ANF (Additional Network Feature) - an added network feature on top of the base PISN signalling and service set.
- WTMI - the wireless terminal call handling case that directs incoming calls to a user when the location is known.
- WTMO - the wireless terminal call handling case that allows the PISN to process call requests from a user at the Home location.
- Q reference point - the signalling interface where this protocol is used.
- PSS1 - the PISN signalling protocol family that this document belongs to.
- QSIG - the informal name for PSS1 used in the foreword.
- ISDN (Integrated Services Digital Network) - the concept base used for the series.
- OSI (Open Systems Interconnection) - the framework used by the series.
Who uses SIST EN 301 827 V1.1.1:2005?
SIST EN 301 827 V1.1.1:2005 is used by telecom engineers, switch and PBX designers, and vendors working on PISN inter-exchange signalling. It is also relevant to network operators, integrators, test labs, and procurement or quality teams that need to confirm support for wireless terminal call handling in a private network.
In practice, users apply it when designing, implementing, or testing QSIG/PSS1 signalling for wireless terminal mobility features, and when checking compatibility with the companion PISN standards listed in clause 3.
What changed in SIST EN 301 827 V1.1.1:2005 from the previous edition?
SIST EN 301 827 V1.1.1:2005 endorses ISO/IEC 15431 (2003) with modifications. The changes stated in the document are:
- insertion of additional normative references in clause 3,
- replacement of ISO/IEC references throughout the text with the corresponding ETSI EN and ETS references,
- replacement of the wording “this International Standard” with “the present document”.
Which standards are used with SIST EN 301 827 V1.1.1:2005?
Clause 3 adds or substitutes companion standards that support addressing, bearer services, supplementary services, and related ANFs. The document points to these ETSI publications:
| Reference | What it contributes |
|---|---|
| ETSI EN 300 189 | Addressing |
| ETSI EN 300 172 | Circuit-mode basic services |
| ETSI EN 300 171 | Circuit-mode 64 kbit/s bearer services |
| ETSI ETS 300 475-1 | Reference configuration for PTN eXchanges (PTNXs) |
| ETSI EN 300 239 | Generic functional protocol for supplementary services |
| ETSI EN 300 238 | Name identification supplementary service |
| ETSI EN 300 257 | Call diversion supplementary service |
| ETSI EN 300 259 | Path replacement ANF |
| ETSI EN 300 362 | Call offer supplementary service |
| ETSI EN 300 364 | Do not disturb and do not disturb override supplementary services |
| ETSI EN 300 426 | Call intrusion supplementary service |
| ETSI EN 301 264 | Advice of charge supplementary services |
| ETSI EN 301 265 | Call interception ANF |
| ETSI EN 301 048 | Transit counter ANF |
| ETSI EN 301 826 | Wireless terminal call handling additional network features |
| ETSI EN 301 255 | Message waiting indication supplementary service |
What does the SIST EN 301 827 V1.1.1:2005 document contain?
The document contains the ETSI foreword, a copyright and IPR notice, national transposition dates, the endorsement notice for ISO/IEC 15431 (2003), and clause 3 material on normative references. It also includes the replacement table that maps ISO/IEC references to ETSI references, and a short document history showing the 2003 approval and 2004 publication steps.
It is therefore mainly a signalling-standard endorsement document with reference substitutions and publication metadata, rather than a document focused on test methods or worked examples.
