ETSIEN 301 131 V1.1.1 (1999-01)61ScopeThe present document defines the stage one of the teleaction bearer service for the pan-European Integrated ServicesDigital Network (ISDN) as provided by European public telecommunications operators. Stage one is an overall servicedescription from the user's point of view (see CCITT Recommendation I.130 [1]), but does not deal with the details ofthe human interface itself.The present document defines the interworking requirements for the teleaction bearer services supported by networksother than ISDN (including private ISDNs) with the teleaction bearer services described in the present document.The present document does not specify the additional requirements where the service is provided to the user via atelecommunications network that is not ISDN but does include interworking requirements of other networks with thepublic ISDN.Charging principles are outside the scope of the present document.Teleaction is a service providing for reliable low volume data communication and allied processing service to the users.The teleaction bearer service can be used for applications such as monitoring, indicating, controlling or verifying ofremote events, operations, and measurements.The present document is applicable to the stage two and stage three standards for the ISDN teleaction bearer service.The terms "stage two" and "stage three" are also defined in CCITT Recommendation I.130 [1]. Where the text indicatesthe status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, or as a capability orpossibility), this needs to be reflected in the text of the relevant stage two and stage three standards. Furthermore,conformance to the present document is met by conforming to the stage three standard with the field of applicationappropriate to the equipment being implemented. Therefore, no method of testing is provided for the present document.2ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, the latest version applies.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]CCITT Recommendation I.130 (1988): "Method for the characterization of telecommunicationservices supported by an ISDN and network capabilities of an ISDN".[2]ITU-T Recommendation I.112 (1993): "Vocabulary of terms for ISDNs".[3]ITU-T Recommendation I.210 (1993): "Principles of telecommunication services supported by anISDN and the means to describe them".[4]CCITT Recommendation Q.9 (1988): "Vocabulary of switching and signalling terms".[5]EN 50136-1-1 (1996): "Alarm systems, Alarm transmission systems and equipment - Part 1-1:General requirements for alarm transmission systems".[6]ITU-T Recommendation X.2 (1996): "International user classes of service in, and categories ofaccess to, public data networks and Integrated Services Digital Networks (ISDNs)".[7]ITU-T Recommendation X.25 (1996): "Interface between Data Terminal Equipment (DTE) andData Circuit-terminating Equipment (DCE) for terminals operating in the packet mode andconnected to public data networks by dedicated circuit".SIST EN 301 131:2000

A TMFP may be the same as the BNP.Teleaction Management Function (TMF): Set of network functions added to either the public ISDN, a private ISDNor assigned to a separate public, or private, network entity. The tasks of the TMF are:-ensure reliable communication paths between the End User Terminals (EUTs) and the Service ProviderTerminal (SPT), i.e. to ensure available and secure access for the EUTs to the network andcommunication paths for the SPT in the ISDN, respectively;-authorization of connected EUTs/SPTs;-EUT/SPT functionality check;-address the appropriate EUT/SPT for transfer of information generated by SPT/EUT;-as a TMFP option, broadcast appropriate EUTs for transfer of information generated by a SPT.The TMF executes these functions by polling the EUTs and the SPTs. The TMF stores status information obtainedthrough the polling procedures. Depending on the application, EUT status information may be sent to the SPT either onrequest or immediately after a change of status has occurred.NOTE 1:If the SP operates through the Packet Switched Data Network or a dedicated network, the TMF isconsidered to be the interworking unit and is, therefore, required to perform adequate protocoltranslation/conversion.NOTE 2:In this description it is expected that all information transfer between an EUT and a SPT is routed via aTMF. This will allow the TMF to verify that an EUT - SPT communication path is available. However,paths directly between EUT and SPT may also be used if the TMF can verify that such a path is available.This is for further study (see also note 4).SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)8NOTE 3:It is expected that the basic ISDN at a later phase will include maintenance functions which may be usedto ensure reliable communications paths between EUTs and SPTs (e.g. maintenance of subscriber access).The TMF may take advantage by using these functions after they will have became available. The ISDNmaintenance functions are for further study.NOTE 4:The possibility of performing TMF functions by means other than polling, e.g. reporting procedures, is forfurther study.Authorization and functionality check of the SPT and EUT are outside the scope of the present document.End User (EU): The one to whom a teleaction application service is provided or who is affected by that applicationservice.Service Provider (SP): The one who, by using one or more TMFs, provides a teleaction application service to one ormore EUs.NOTE 5:The SP may be the BNP, the TMFP, or another organization responsible for one or more SPT.End User Terminal (EUT): A device (or location of a device) that, depending on the application (e.g. by monitoring ofsubdevices):-on the basis of local conditions or by interrogation, generates information and presents this informationfor transmission by the network to a SPT;-receives information from a SPT in order to affect local conditions;-upon polling requests received from a TMF executes the requested local actions (e.g. authorization,functionality checks, etc.) and sends appropriate responses to the TMF.NOTE 6:Authorization and functionality checks are outside the scope of the present document.Service Provider Terminal (SPT): A device (or location of such a device) which, depending on the application:-receives information from one or more EUTs for handling and processing in accordance with theapplication service offered by the Service Provider (SP);-generates control messages and information requests and presents that information for transmission to oneor more EUTs;-monitors EUTs on the network, either by retrieving EUT status information stored in TMFs, and/or byreceiving status information automatically from TMFs (e.g. alarms);-receives polling requests from TMFs and sends appropriate responses to the TMF;-transfers to the TMF information to be broadcasted to the EUTs, if the broadcast functionality issupported by the TMF.NOTE 7:Execution of local procedures such as authorization and functionality check are outside the scope of thepresent document.EU access capability: The telecommunication means used between an EUT and a TMF (e.g. ISDN bearer service,dedicated connection, etc.).SPT access capability: The telecommunication means used between a SPT and a TMF (e.g. ISDN bearer service,dedicated connection, etc.).Teleaction application: The teleaction application is one specific end to end application offered by a service providerusing the teleaction bearer service.Teleaction bearer service: The teleaction bearer service is the transport mechanism used by a teleaction application.SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)93.2AbbreviationsFor the purposes of the present document, the following abbreviations apply:BNPBasic Network ProviderDTNDedicated Teleaction NetworkEUEnd UserEUTEnd User TerminalISDNIntegrated Services Digital NetworkPLLPermanent Logical LinkSPService ProviderSPTService Provider TerminalTMFTeleaction Management FunctionTMFPTeleaction Management Function Provider4DescriptionTeleaction is a service providing for reliable low volume data communication and allied processing service to the users.The teleaction bearer service can be used for applications such as monitoring, indicating, controlling or verifying ofremote events, operations, and measurements.The teleaction bearer service allows the exchange of low volume digital information between the End User (EU) and SP.A two-way simultaneous information transfer shall be continuously available during the information transfer phase. Thisshall apply also in such cases where only one-way information transfer is required by the application. The teleactionbearer service shall connect EUs to one or more SPs. Each EUT is logically associated with only one SPT. An EU mayconsist of more than one EUT. Messages from EUs shall be conveyed to one or more SPs, and vice versa.NOTE 1:The context where one EUT communicates with several SPTs is outside the scope of the presentdocument.EUs and SPs shall access the network via ISDN T reference point, or coincident S and T reference point usingstandardized protocols defined for teleaction.NOTE 2:SPs may be connected to networks other than ISDN. Interworking with these networks will then benecessary.The applications of the teleaction bearer service can be divided into two basic categories, each with its own networkimplications and specific security functions. These categories are:1)applications without other specific requirements regarding service reliability and security functions than thoseoffered by the bearer service, i.e. non-sensitive applications;2)applications with additional security and reliability requirements, i.e. sensitive applications.Several levels of reliability and security shall, therefore, be offered with the teleaction bearer service in order to ensurereliable communications paths between the EUs and the SPs, and to prevent unauthorized data traffic or unauthorizedaccess to EU data. To achieve this goal, TMFs shall be either added to the basic ISDN network or be assigned to aseparate entity. The level of reliability and security shall be application dependent (see clause 8). Transmission delaybetween EUT and SPT shall conform to the delay categories defined in subclause 8.4.1 as appropriate for the serviceapplication.SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)105ProceduresThe context used when defining these procedures is outlined in annex A.5.1Provision and withdrawalBasic Network Provider (BNP) and TMFP can be different organizations.The teleaction bearer service shall be provided by the BNP on demand of one of the two linked parties with the assent ofthe other party.Depending on the service provision characteristics, several subscription arrangements can be possible, e.g. indication ofspecial user requirements (periodicity of polling, etc.).The teleaction bearer service shall be withdrawn if requested by one party, by the BNP, or for administrative reasons.5.2Normal Procedures5.2.1Activation, Deactivation, Registration5.2.1.1ActivationActivation of the teleaction bearer service shall be performed by the BNP.Activation shall make the necessary access capabilities available to both the EUT and the SPT (bearer service, dedicatedconnections, etc.) and shall also include activation of the TMF (starts EUT polling, etc.). The operation of the TMFshall be as described in subclause 6.2.2.NOTE:As seen from the EU, activation of the teleaction bearer service makes the teleaction application supportedby the SP available to the user (ready for invocations, e.g. send an alarm).As seen from the SP, the teleaction application shall be made available through the network. Thereafter the applicationsupported by the SP can be made available (activated) for each specific EU subscribing to the teleaction bearer service.As a service provider option, the EU can have the possibility to dynamically activate the teleaction bearer service.5.2.1.2DeactivationDeactivation of the teleaction bearer service shall be performed by the BNP.As a SP option, the EU can have the possibility to dynamically deactivate the teleaction bearer service.5.2.1.3RegistrationAs a TMFP option, registration procedures can exist to enable the SP to choose the level of reliability, security and/ortransmission delay as well as the SPT polling intervals used by the TMF. For some applications one or more of theselevels may be fixed at provision time and may not be individually set (or reset) by the SP.According to the level(s) offered by the SP, the EU can, as a TMFP option, select the appropriate level based oncorresponding procedure.The procedures used by the EU and the registration procedures for SPs are outside the scope of the present document.SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)115.2.2 Invocation and Operation5.2.2.1 Originating the service (call establishment)The establishment of communication between an EUT and a SPT happens in two phases:Phase 1:Establishment of a communication path between EUT and TMF, and a communication pathbetween SPT and TMF.Phase 2:Establishment of a communication path between EUT and SPT using the two communicationpaths established in phase 1.NOTE 1:All information transfer between an EUT and a SPT is routed via a TMF (see note 2 in clause 3, TMFdefinition).NOTE 2:A phase 1 communication path between a SPT and a TMF may be used for several phase 2communication paths.The originating party can be the EUT or the SPT (application and situation dependent). EUT, SPT, or TMF may initiatephase 1 establishment. EUT or SPT may initiate phase 2 establishment.The two phase 1 communications paths can have different modes, and shall be independent from the mode used for thephase 2 path.Phase 1 establishment, EUT - TMF, and SPT - TMF:- permanent connection mode: establishment shall take place at activation t

A TMFP may be the same as the BNP.Teleaction Management Function (TMF): Set of network functions added to either the public ISDN, a private ISDNor assigned to a separate public, or private, network entity. The tasks of the TMF are:-ensure reliable communication paths between the End User Terminals (EUTs) and the Service ProviderTerminal (SPT), i.e. to ensure available and secure access for the EUTs to the network andcommunication paths for the SPT in the ISDN, respectively;-authorization of connected EUTs/SPTs;-EUT/SPT functionality check;-address the appropriate EUT/SPT for transfer of information generated by SPT/EUT;-as a TMFP option, broadcast appropriate EUTs for transfer of information generated by a SPT.The TMF executes these functions by polling the EUTs and the SPTs. The TMF stores status information obtainedthrough the polling procedures. Depending on the application, EUT status information may be sent to the SPT either onrequest or immediately after a change of status has occurred.NOTE 1:If the SP operates through the Packet Switched Data Network or a dedicated network, the TMF isconsidered to be the interworking unit and is, therefore, required to perform adequate protocoltranslation/conversion.NOTE 2:In this description it is expected that all information transfer between an EUT and a SPT is routed via aTMF. This will allow the TMF to verify that an EUT - SPT communication path is available. However,paths directly between EUT and SPT may also be used if the TMF can verify that such a path is available.This is for further study (see also note 4).SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)8NOTE 3:It is expected that the basic ISDN at a later phase will include maintenance functions which may be usedto ensure reliable communications paths between EUTs and SPTs (e.g. maintenance of subscriber access).The TMF may take advantage by using these functions after they will have became available. The ISDNmaintenance functions are for further study.NOTE 4:The possibility of performing TMF functions by means other than polling, e.g. reporting procedures, is forfurther study.Authorization and functionality check of the SPT and EUT are outside the scope of the present document.End User (EU): The one to whom a teleaction application service is provided or who is affected by that applicationservice.Service Provider (SP): The one who, by using one or more TMFs, provides a teleaction application service to one ormore EUs.NOTE 5:The SP may be the BNP, the TMFP, or another organization responsible for one or more SPT.End User Terminal (EUT): A device (or location of a device) that, depending on the application (e.g. by monitoring ofsubdevices):-on the basis of local conditions or by interrogation, generates information and presents this informationfor transmission by the network to a SPT;-receives information from a SPT in order to affect local conditions;-upon polling requests received from a TMF executes the requested local actions (e.g. authorization,functionality checks, etc.) and sends appropriate responses to the TMF.NOTE 6:Authorization and functionality checks are outside the scope of the present document.Service Provider Terminal (SPT): A device (or location of such a device) which, depending on the application:-receives information from one or more EUTs for handling and processing in accordance with theapplication service offered by the Service Provider (SP);-generates control messages and information requests and presents that information for transmission to oneor more EUTs;-monitors EUTs on the network, either by retrieving EUT status information stored in TMFs, and/or byreceiving status information automatically from TMFs (e.g. alarms);-receives polling requests from TMFs and sends appropriate responses to the TMF;-transfers to the TMF information to be broadcasted to the EUTs, if the broadcast functionality issupported by the TMF.NOTE 7:Execution of local procedures such as authorization and functionality check are outside the scope of thepresent document.EU access capability: The telecommunication means used between an EUT and a TMF (e.g. ISDN bearer service,dedicated connection, etc.).SPT access capability: The telecommunication means used between a SPT and a TMF (e.g. ISDN bearer service,dedicated connection, etc.).Teleaction application: The teleaction application is one specific end to end application offered by a service providerusing the teleaction bearer service.Teleaction bearer service: The teleaction bearer service is the transport mechanism used by a teleaction application.SIST EN 301 131:2000

Thisshall apply also in such cases where only one-way information transfer is required by the application. The teleactionbearer service shall connect EUs to one or more SPs. Each EUT is logically associated with only one SPT. An EU mayconsist of more than one EUT. Messages from EUs shall be conveyed to one or more SPs, and vice versa.NOTE 1:The context where one EUT communicates with several SPTs is outside the scope of the presentdocument.EUs and SPs shall access the network via ISDN T reference point, or coincident S and T reference point usingstandardized protocols defined for teleaction.NOTE 2:SPs may be connected to networks other than ISDN. Interworking with these networks will then benecessary.The applications of the teleaction bearer service can be divided into two basic categories, each with its own networkimplications and specific security functions. These categories are:1)applications without other specific requirements regarding service reliability and security functions than thoseoffered by the bearer service, i.e. non-sensitive applications;2)applications with additional security and reliability requirements, i.e. sensitive applications.Several levels of reliability and security shall, therefore, be offered with the teleaction bearer service in order to ensurereliable communications paths between the EUs and the SPs, and to prevent unauthorized data traffic or unauthorizedaccess to EU data. To achieve this goal, TMFs shall be either added to the basic ISDN network or be assigned to aseparate entity. The level of reliability and security shall be application dependent (see clause 8). Transmission delaybetween EUT and SPT shall conform to the delay categories defined in subclause 8.4.1 as appropriate for the serviceapplication.SIST EN 301 131:2000



ETSIEN 301 131 V1.1.1 (1999-01)105ProceduresThe context used when defining these procedures is outlined in annex A.5.1Provision and withdrawalBasic Network Provider (BNP) and TMFP can be different organizations.The teleaction bearer service shall be provided by the BNP on demand of one of the two linked parties with the assent ofthe other party.Depending on the service provision characteristics, several subscription arrangements can be possible, e.g. indication ofspecial user requirements (periodicity of polling, etc.).The teleaction bearer service shall be withdrawn if requested by one party, by the BNP, or for administrative reasons.5.2Normal Procedures5.2.1Activation, Deactivation, Registration5.2.1.1ActivationActivation of the teleaction bearer service shall be performed by the BNP.Activation shall make the necessary access capabilities available to both the EUT and the SPT (bearer service, dedicatedconnections, etc.) and shall also include activation of the TMF (starts EUT polling, etc.). The operation of the TMFshall be as described in subclause 6.2.2.NOTE:As seen from the EU, activation of the teleaction bearer service makes the teleaction application supportedby the SP available to the user (ready for invocations, e.g. send an alarm).As seen from the SP, the teleaction application shall be made available through the network. Thereafter the applicationsupported by the SP can be made available (activated) for each specific EU subscribing to the teleaction bearer service.As a service provider option, the EU can have the possibility to dynamically activate the teleaction bearer service.5.2.1.2DeactivationDeactivation of the teleaction bearer service shall be performed by the BNP.As a SP option, the EU can have the possibility to dynamically deactivate the teleaction bearer service.5.2.1.3RegistrationAs a TMFP option, registration procedures can exist to enable the SP to choose the level of reliability, security and/ortransmission delay as well as the SPT polling intervals used by the TMF. For some applications one or more of theselevels may be fixed at provision time and may not be individually set (or reset) by the SP.According to the level(s) offered by the SP, the EU can, as a TMFP option, select the appropriate level based oncorresponding procedure.The procedures used by the EU and the registration procedures for SPs are outside the scope of the present document.SIST EN 301 131:2000
