- Abstract
This ETS defines a set of bearer services to be provided to GSM PLMN subscribers by a GSM PLMN itself and in connection with other networks. This ETS should also be used as a reference for defining the corresponding required mobile network capabilities which are specified by means of the GSM PLMN connection type concept, defined in GSM 03.10. The recommended provision of the bearer services is under the control of the GSM MoU and is out of the scope of ETSI/TC/SMG. Bearer services not included in this specification that require modifications to the GSM signalling specifications should not be introduced unilaterally by a mobile network operator.

SIST ETS 300 904 E2:2003 is the Slovenian adoption of ETS 300 904 Edition 2, a European Telecommunications Standard for GSM Phase 2+ bearer services. It specifies the bearer services supported by a GSM Public Land Mobile Network (PLMN) for its subscribers and for interworking with other networks. In practice, it gives network operators, designers, and buyers a reference for what service categories and network capabilities a GSM PLMN is expected to support.
What does SIST ETS 300 904 E2:2003 specify?
SIST ETS 300 904 E2:2003 defines a set of bearer services for use in a GSM PLMN and in connection with other networks. The standard also serves as the reference for the related mobile network capabilities described through the GSM PLMN connection type concept in GSM 03.10.
The scope also makes two practical points clear: recommended provision is controlled by the GSM MoU and is outside ETSI TC-SMG scope, and bearer services that are not included here should not be introduced by a mobile network operator if they would require changes to GSM signalling.
| Annex | What it covers |
|---|---|
| A (informative) | Change history |
The document is organized into scope, normative references, abbreviations, a framework for bearer services, bearer service categories, detailed bearer service definitions, and an informative change history annex.
What are the key requirements of SIST ETS 300 904 E2:2003?
SIST ETS 300 904 E2:2003 defines bearer services through a set of independent attributes, and the standard bases its service definitions on the Minimal Set of attributes. That matters because it lets a network describe a bearer service in a consistent way across originating, transit, and terminating networks.
Attribute framework
Clause 1 groups bearer service attributes into four categories: information transfer, access, interworking, and general. In practice, this is the checklist used to describe what the service carries, how the user reaches it, how it connects to the far-end network, and what general behavior applies.
Clause 1 also points to GSM 02.01 for the attribute definitions and to GSM 03.10 and the GSM 09-series for interworking details. That means the service description in this standard is only one part of the overall GSM capability model.
Common bearer service behavior
Clause 3 gives the values shared by all GSM bearer services: circuit mode, demand establishment, bi-directional symmetric communication, and point-to-point configuration. The information transfer rate is not treated as a single fixed value because it depends on the reference point.
For asynchronous NT bearer services, the standard says data compression may be supported. Clause 3 also says GSM NT Bearer Services 2x and 3x may support V.120 interworking, which affects compatibility with ISDN terminal adapters.
Service categories and service types
Clause 2 groups the bearer services into UDI, 3,1 kHz external to the PLMN, PAD, Packet, Alternate Speech/Data, and Speech followed by Data. In practice, these categories tell you whether the connection is unrestricted digital, modem-oriented, packet-oriented, or able to switch between speech and data.
Clause 3 then assigns bearer service numbers and access structures to the services. The list covers asynchronous and synchronous general bearer services, PAD access bearer services, packet access bearer services, and the speech/data switching services. Some entries are limited to Mobile Originated calls, so service planning must check whether the intended call direction is allowed.
General bearer service user data characteristics
Subclause 3.1 gives detailed user data characteristics for the general bearer services. The tables cover 3,1 kHz Audio, V.110 UDI, X.31 Flag Stuffing UDI, V.120, and Bit Transparent Mode, which helps match the bearer service to the terminal adaptation or interworking method required by the application.
What terms does SIST ETS 300 904 E2:2003 define?
- GSM Public Land Mobile Network (PLMN) - The GSM network that provides the bearer services and interworks with other networks.
- Unrestricted Digital Information (UDI) - A bearer service category for transferring digital information without speech-style restrictions.
- Packet Assembly/Disassembly (PAD) - The access method used for asynchronous access to packet networks.
- Interworking Function (IWF) - The network function that supports interworking, including 3,1 kHz audio and modem selection.
- Terminal Adaptation Functions (TAF) - The functions that adapt terminal equipment to GSM bearer capabilities.
- Mobile Station (MS) - The subscriber equipment that connects to the GSM network.
- Mobile Switching Centre (MSC) - The network switching node used in bearer service and interworking handling.
Who uses SIST ETS 300 904 E2:2003?
SIST ETS 300 904 E2:2003 is used by GSM network operators, mobile network planners, and interworking engineers who need to define supported bearer services. It is also relevant to terminal and modem designers, because the service tables and V.120-related material affect how equipment connects to the network. Quality managers and buyers use it to check whether a GSM PLMN supports the bearer service categories needed for voice/data switching, packet access, or fixed-network interworking.
What changed in SIST ETS 300 904 E2:2003 from the previous edition?
Annex A records a change history entry for HSCSD use of multiple TS in alternate and followed-by services. The document history also shows the transition through earlier GSM 02.02 versions to this second edition.
Which standards are used with SIST ETS 300 904 E2:2003?
- GSM 01.04 - Provides the abbreviations and acronyms used in the standard.
- GSM 02.01 - Defines the general principles and bearer service attributes.
- GSM 02.04 - Covers supplementary services.
- GSM 03.10 - Defines GSM PLMN connection types used as the capability reference.
- GSM 04.02 - Defines the GSM PLMN access reference configuration.
- GSM 07.01, GSM 07.02, GSM 07.03, GSM 07.05 - Cover terminal adaptation functions and DTE-DCE interface use for bearer capabilities and SMS/CBS.
- GSM 09.02, GSM 09.03, GSM 09.04, GSM 09.05, GSM 09.06, GSM 09.07, GSM 09.10, GSM 09.11 - Cover MAP and interworking with ISDN, PSTN, CSPDN, PSPDN, and supplementary services.
- CCITT Recommendation V.120 - Provides the ISDN data terminal equipment support used for V.120 interworking.
What does the SIST ETS 300 904 E2:2003 document contain?
The document contains a framework for describing bearer services, a category breakdown for the service types, and a table of bearer service numbers with their attribute values. It also includes detailed subclauses for the general bearer services, showing user data characteristics for several access methods and interworking options.
Figure 1 explains how the attribute groups apply across originating, transit, and terminating networks. Figure 2 shows the V.120 interworking model between a mobile station and ISDN. For implementation work, the tables and figures support service design, network capability planning, and interworking verification.

1 Framework for defining Bearer Services
Bearer Services are described by attributes, which are intended to be independent. These attributes are
described and defined in GSM 02.01 [2]. They are grouped into four categories:
i) Information transfer attributes, which characterize the network capabilities for transferring
information from a user access point in a GSM PLMN to a user access point in another network.
(Refer to GSM 02.01 [2] and GSM 04.02 [5] for definitions of user access points, originating and
terminating networks).
ii) Access attributes, which describe the means for accessing network functions or facilities as seen at
the access point in the PLMN (see GSM 02.01 [2]).
iii) Interworking attributes, which describe properties of the terminating network and its access point.
The terminating network may include another GSM PLMN or the originating PLMN (see
GSM 02.01 [2]).
iv) General attributes, which deal with the service in general.
Figure 1 shows the relation between the groups of attributes and their fields of applicability.
