ETSI EN 301 145-1:1998 Integrated Services Digital Network (ISDN); Digital Subscriber Signalling System No. One (DSS1) Protocol; Teleaction Teleservice; Part 1: Protocol Specification (V1.1.1)
The present document specifies the stage three of the Teleaction bearer service for the pan-european Integrated Services Digital Network (ISDN) as provided by the European public telecommunication operators at the T reference point or coincident S and T reference point (as defined in CCITT Recommendation I.411 [1]). Stage three identifies the protocol procedures and switching functions needed to support a telecommunications service (see CCITT Recommendation I.130 [2]). The present document also provides guidance on the network functionality required to implement the Teleaction service (see annex B). The functional capabilities and information flows of such network entities are described. In the absence of a stage 2 description this information has been included in the present document. This does not preclude its future publication as a separate stage 2 standard. In addition@ the present document specifies the protocol requirements at the T reference point where the service is provided to the user via a private ISDN. The present document does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN@ but does include interworking requirements of other networks with the public ISDN. Teleaction is a service providing for reliable@ low volume@ data communication and allied processing to users. The Teleaction bearer service may be used for applications such as monitoring@ indicating@ controlling and verifying of remote events@ operations@ and measurements. Charging principles are outside the scope of the present document. Further parts of the present document specify the method of testing required to identify conformance to the present document. The present document is applicable to equipment@ supporting the Teleaction bearer service@ to be attached at either side of a T reference point or coincident S or T reference point when used as an access to the public ISDN.
