SIST EN 300 171 V1.2.1:2005 is the Slovenian adoption of the European Telecommunications Standard EN 300 171 V1.2.1 for Private Integrated Services Network (PISN) circuit-mode basic services. It specifies the service description, functional capabilities and information flows for standardised circuit-mode bearer services that a PISN may support, for network designers, equipment vendors and service implementers.
What does SIST EN 300 171 V1.2.1:2005 specify?
SIST EN 300 171 V1.2.1:2005 specifies the control aspects of circuit-mode basic services in a PISN. In practice, that means the document describes how these bearer services are represented, controlled and exchanged as information flows, and how optional teleservices relate to those bearer capabilities.
| Annex | What it covers |
|---|---|
| Annex B | Teleservices and the bearer capabilities needed to support them |
| Annex C | Bibliographic references |
| Annex ZD | Corrections to ISO/IEC 11574 |
The document is organized around the main service description and control aspects, with Annex B giving the operational detail for supported teleservices and Annex ZD listing editorial and technical corrections to ISO/IEC 11574.
What are the key requirements of SIST EN 300 171 V1.2.1:2005?
SIST EN 300 171 V1.2.1:2005 treats teleservice support as optional, but when a PISN supports one of the listed teleservices it shall comply with Annex B. For a buyer or implementer, this means the network must be checked against the bearer capabilities in the annex before claiming support for those services.
Clause 2 sets out the normative references and states how dated and undated references are to be read. This matters because the standard depends on other ETS standards for addressing, service specification method and reference configuration.
Annex B requires the PISN to convey the teleservice being used as High Layer Compatibility (HLC) information from the calling user to the called user. In practice, the network may carry the indication, but any use of that indication by the PISN itself is outside the scope of the document.
Annex B also allows the PISN to reject a teleservice request if the requested bearer capabilities are not those specified there. That gives implementers a clear acceptance check: if the bearer profile does not match, the request can be refused.
For the Telephony 3,1 kHz teleservice, Annex B ties the request to circuit mode, 64 kbit/s, speech, 8 kHz integrity, demand establishment, bi-directional symmetric, point-to-point communication and B access with ITU-T Recommendation G.711 access protocol. In practice, this is the service profile to use for conventional speech calls.
For the Telefax group 4 teleservice and the circuit-mode syntax-based videotex teleservice, Annex B uses circuit mode, 64 kbit/s, unrestricted transfer capability, unstructured communication, demand establishment, bi-directional symmetric, point-to-point communication and B access with ISO/IEC 7776 and ISO/IEC 8208 access protocols. This tells implementers that both services use a similar circuit-mode bearer profile, with packet-mode bearer capability outside the scope of this edition.
Clause 13 and Clause 14, together with the later corrections in Annex ZD, show that the document also defines how call-control information elements and interworking cases are handled. For readers testing implementations, these sections are the parts to check when validating SETUP, response, confirmation and reporting behaviour.
What terms does SIST EN 300 171 V1.2.1:2005 define?
- PISN - Private Integrated Services Network, the network type the standard is written for.
- Bearer service - A circuit-mode transport service that provides the communication path and attributes used by higher-layer user services.
- Teleservice - A user-facing service such as telephony or telefax that can be supported over the bearer capabilities defined here.
- High Layer Compatibility (HLC) - An information indication used to identify the teleservice being used and passed from the calling user to the called user.
- Low Layer Compatibility (LLC) - Compatibility information used in call handling and compatibility checking at service connection time.
- PINX - PISN exchange, the exchange entity referenced in the companion reference configuration standard.
- ISDN - Integrated Services Digital Network, the conceptual framework the series uses for service and signalling definitions.
Who uses SIST EN 300 171 V1.2.1:2005?
SIST EN 300 171 V1.2.1:2005 is used by people who design, specify or implement services in a PISN. That includes network architects, PBX/PISN equipment vendors, signalling engineers and terminal developers.
It is also relevant to quality and test teams checking whether an implementation supports the listed circuit-mode bearer services and teleservices. Service providers and buyers use it to confirm what service behaviour, compatibility information and call-control handling they can expect.
What changed in SIST EN 300 171 V1.2.1:2005 from the previous edition?
SIST EN 300 171 V1.2.1:2005 replaces the earlier standalone basic-services specification by endorsing ISO/IEC 11574 (1994) with modifications. The foreword says the earlier edition was a standalone specification and this edition adopts the international text.
The document also:
- updates clause 2 with ETS 300 189, ETS 300 387 and ETS 300 475-1 as European Standards references;
- replaces several references throughout the text with the ETS standards named above;
- replaces the term “International Standard” with “EN” throughout the ISO/IEC 11574 text;
- replaces Annex B with a teleservices annex;
- adds Annex ZD with corrections to ISO/IEC 11574.
Which standards are used with SIST EN 300 171 V1.2.1:2005?
Clause 2 names ETS 300 189 for addressing, ETS 300 387 for the specification method for basic and supplementary services, and ETS 300 475-1 for the PISN reference configuration. Annex B also points to ISO/IEC 7776 and ISO/IEC 8208 for access protocols used with telefax group 4 and circuit-mode syntax-based videotex teleservices.
For additional background, Annex B cites ETS 300 111, ETS 300 120 and ETS 300 262 for the related teleservices, and ETR 018 and ETR 076 for compatibility and standards guidance.
What does the SIST EN 300 171 V1.2.1:2005 document contain?
SIST EN 300 171 V1.2.1:2005 contains service-description material, information-flow requirements and detailed bearer-capability profiles. Annex B provides the low-layer attribute sets for the supported teleservices, including the transfer mode, rate, capability, symmetry, configuration, access channel and access protocol.
It also contains call-control-related tables and notes in later clauses, including information-element handling for setup, response, confirmation and report flows. Annex ZD lists correction items for specific subclauses of ISO/IEC 11574, which is useful when comparing the EN text with the underlying international standard.

GeneralA PISN can support teleservices requiring the same bearer capabilities as the bearer services specified in the presentdocument. These teleservices include, for example:-
Telephony 3,1 kHz teleservice;-
Telefax group 4 teleservice; and-
Circuit-mode syntax-based videotex teleservice.The support by a PISN of one or more of these teleservices is optional. However, if a PISN supports one or more ofthese teleservices then it shall comply with this annex.The bearer capabilities and other special requirements used to support these teleservices are specified below. Otherwise,the impact of these teleservices on the network is the same as for the corresponding bearer service.The PISN shall convey an indication of the teleservice being used as High Layer Compatibility (HLC) information, fromthe calling PISN user to the called PISN user. Any use of this indication by the PISN is outside the scope of the presentdocument.A PISN may reject a request for a teleservice if the requested bearer capabilities are not those specified in this annex.NOTE 1:
Additional information can be found in the following ETSs:ETS 300 111 (Telephony 3,1 kHz);ETS 300 120 (Telefax group 4); andETS 300 262 (Circuit-mode syntax-based videotex).NOTE 2:
The support of other teleservices is not precluded. ETR 018 and ETR 076 contain guidance regardingother teleservices that can be supported using the bearer capabilities defined by the present document.High layer functions for interworking between these teleservices and non-ISDN networks are beyond the scope of thepresent document.SIST EN 300 171 V1.2.1:2005
