157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 4.4 Videotex host accessed via VSC | Though the Videotex Access Function is explicitly separate with respect to the Videotex host, no impact results on the overall Network architecture.
Actually the VSC can be considered a front-end function of the same Videotex host (either physically separate or integrated), so that all the above configuration in princi... |

157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 6 Bearer Service configuration and settings | Support of Videotex service on the the GSM PLMN is via GSM standard Bearer Services, as specified in various GSM Technical Specificationa. In the following specific reference on the main technical aspects are reviewed. |
157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 6.1 Connection Types | Transparent or non-transparent network support can be requested to the GSM PLMN for Videotex service.
The information transfer protocol models are those in figure 6/GSM 03.10, models 1a, 2a, 3a, 4a for ISDN-related MS configurations, and models 1b, 2b, 3b, 4b for PSTN-related MS configurations.
Concerning "Circuit mode... |
157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 6.2 Terminal Adaption functions | The TAFs used for Videotex are the asynchronous and synchronous standards defined in GSM 07-series; rate adaption functions are those specified in GSM 04.21 and GSM 08.20. |
157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 6.3 Signalling aspects | All GSM standard rates (up to 9 600 bit/s) can be used for Videotex on a GSM PLMN; appropriate settings in BC-IE and LLC (where applicable) fix the rate on the GSM connection, and identify the voiceband modem to be used (when applicable) by the IWF.
When a 1 200/75 bit/s Bearer Capability is requested, the 75 bit/s rat... |
157bacc4edc4bb5d3eed6ec0265827dd | 03.43 | 6.4 Network interworking | Ad-hoc Specifications are devoted in the GSM normative to explicitly cover the aspects of PLMN interworking; being Videotex service a generic application running on top of GSM standard Bearer services, all technical aspects in those GSM specifications apply.
The reference are:
- GSM 09.07, which details interworking re... |

fcc930975597116eb21de958d20d3f3d | 03.56 | 4.1 CTS definition | The CTS operator can provide a CTS service which allows (using a modified GSM radio interface) to provide a cordless telephone service attached to the fixed network or to a cellular network. The services offered by CTS are limited to the type of network to which the CTS-FP is connected. In order to offer this service t... |
fcc930975597116eb21de958d20d3f3d | 03.56 | 4.2 CTS Network | A CTS network is defined to be made up of one or more CTS cells. When a CTS network has more than one cell these cells are synchronised (in frequency, at TDMA frame edges and TDMA frame number) on the radio interface. |
fcc930975597116eb21de958d20d3f3d | 03.56 | 4.3 CTS Role models | |
fcc930975597116eb21de958d20d3f3d | 03.56 | 4.3.1 CTS FP owner's role model | CTS role model for a CTS FP subscriber
In order to receive a valid CTS-GFL the CTS-FP owner needs to have a subscription (2) with a CTS operator. This subscription is materialised by a CTS-SIM card stored in the CTS-FP. The CTS operator has an agreement (3) with a DPLMN part of a GSM operator1 to use its frequencies fo... |
fcc930975597116eb21de958d20d3f3d | 03.56 | 4.3.2 CTS MS subscriber's role model | CTS MS subscriber's role model
The CTS-MS subscriber has a valid subscription (1) with a GSM operator who allows CTS operations. In case of roaming, the VPLMN shall confirm the authorisation to do CTS operations to this CTS-MS.
The CTS MS subscriber has agreement (2) with one CTS-FP owner that allows him to enrol on hi... |
