SIST EN 301 195 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 195 V1.1.1, a European telecommunications standard for Digital Video Broadcasting (DVB) interaction channels through the Global System for Mobile communications (GSM). It specifies how GSM can be used to provide the narrowband return path and related interworking needed for interactive DVB services. The standard is written for DVB system designers, terminal suppliers, and network operators that need a GSM-based interaction channel.

What does SIST EN 301 195 V1.1.1:2003 specify?

SIST EN 301 195 V1.1.1:2003 specifies the baseline solution for providing a DVB interaction channel over GSM. It focuses on the GSM-specific part of the interaction network and on how that network connects the user terminal to the service provider.

The document is organized into:

• Clause 1 - scope
• Clause 2 - references
• Clause 3 - abbreviations
• Clause 4 - reference model
• Clause 5 - DVB interaction channel specification for GSM
• Annex A - informative background on GSM
• Annex B - informative interworking types

Annex	What it covers
Annex A	Basic characteristics of GSM and future GSM data services
Annex B	Interworking types, including PSTN and ISDN

The scope states that the GSM solution can be used with satellite, cable, MATV, SMATV, terrestrial, microwave, or other DVB broadcasting and distribution systems. The document also treats the GSM-based interaction channel as one option within a wider set of interactive service solutions.

What are the key requirements of SIST EN 301 195 V1.1.1:2003?

The standard defines the GSM part of the DVB interaction channel in terms of architecture, interfaces, call handling, and interworking.

Reference model and layering

Clause 4 uses a simplified model with a Physical layer and a Transport layer. The application layer is left outside the document, which matters because service providers can implement different interactive applications while keeping the same GSM transport solution. Clause 4 also separates the Broadcast Channel (BC) from the Interaction Channel (IC), with the IC split into a return interaction path and a forward interaction path.

User terminal structure

Clause 4 identifies the user terminal as a Set Top Box (STB) made up of the Network Interface Unit (NIU) and the Set Top Unit (STU). The NIU includes the Broadcast Interface Module (BIM) and the Interactive Interface Module (IIM). In practice, this tells integrators where the GSM connection sits and which part of the terminal handles interaction traffic.

GSM as the interaction network

Clause 5 states that GSM can provide the wireless bi-directional path for the interaction channel. The user terminal needs a GSM Mobile Station (MS) as the IIM, and the GSM network may be complemented by another network, commonly Public Switched Telephone Network (PSTN) or Integrated Services Digital Network (ISDN), to reach the service provider. This matters because the end-to-end path may include more than GSM alone.

Physical interfaces

Subclause 5.1 distinguishes external and integrated MS configurations. An external MS follows the user-terminal to MS interface requirements of GSM 07.06 and EN 50201 modem-interface practice. An integrated MS follows the same requirements, except for the 9-pin connector. This is the section to use when designing hardware connections and cabling.

Calling procedures and disconnection

Subclause 5.2 requires connection establishment according to the GSM 04 series, with signalling described by GSM 04.08. If the service provider cannot be reached, upper layers are responsible for retrying the call or informing the user. Subclause 5.3 allows forced disconnection for emergency calls through upper-layer signalling.

Interworking choices

Annex B explains how GSM can interwork with PSTN and ISDN. The document notes that GSM-ISDN interworking is preferable when possible because it gives an end-to-end digital link and shorter setup times. For readers planning network integration, this is the practical section for choosing bearer capabilities and interworking behavior.

What terms does SIST EN 301 195 V1.1.1:2003 define?

• Broadcast Channel (BC) - The one-way broadband path from the service provider to users, carrying broadcast content and possibly forward interaction data.
• Interaction Channel (IC) - The two-way channel used for requests, replies, and other interactive service communication.
• Set Top Box (STB) - The user terminal that combines broadcast and interaction functions.
• Interactive Interface Module (IIM) - The part of the user terminal that connects to the interaction network.
• Mobile Station (MS) - The GSM terminal used as the interaction interface.
• Network Interface Unit (NIU) - The user-terminal unit made up of the BIM and IIM.
• PSTN - The Public Switched Telephone Network used as a possible interworking network.
• ISDN - The Integrated Services Digital Network used as another possible interworking network.

Who uses SIST EN 301 195 V1.1.1:2003?

SIST EN 301 195 V1.1.1:2003 is used by people defining and implementing interactive DVB services over GSM. Typical users include:

• DVB and broadcast system architects
• Set-top box and terminal designers
• GSM network planners and interworking engineers
• Service providers building return-channel services
• Test and integration teams checking call setup, bearer choice, and terminal interfaces
• Procurement and quality teams confirming that a DVB terminal supports a GSM-based interaction channel

Which standards are used with SIST EN 301 195 V1.1.1:2003?

The document relies on several related ETSI and CENELEC texts:

• ETS 300 802 - network-independent protocols for DVB interactive services
• EN 50201 - modem interface requirements for DVB-IRD equipment
• GSM 07.01 and GSM 07.02 - terminal adaptation functions for Mobile Stations
• GSM 07.06 - V. series DTE-DCE interface at the Mobile Station
• GSM 04.08 - Layer 3 signalling used for call setup
• GSM 09.03 and GSM 09.07 - interworking between GSM and ISDN/PSTN
• DVB-A008 - commercial requirements for asymmetric interactive services
• ETS 300 500, 501, 522, 528, 550, 551, 552, 554, 555, 562, and GSM 04.22 - the GSM service, bearer, network, access, data link, and rate-adaptation background used by the specification

What does the SIST EN 301 195 V1.1.1:2003 document contain?

The document contains a reference model for narrowband interaction channels in a broadband DVB scenario, including figures for the protocol stack and the system architecture. Clause 5 sets out the GSM-based physical interface, calling procedure, and forced-disconnection behavior. Annex A summarizes GSM characteristics and data services, including SMS, bearer services, and newer packet or high-speed services. Annex B describes PSTN and ISDN interworking, including bearer capability mapping and the role of interworking functions. A table in Annex B compares bearer service categories across GSM, ISDN, and PSTN, which is useful when selecting the right end-to-end connection type.
