Abstract: Device for connecting a sensor, which has a conical sealing cone and an external screwthread in front of the sealing cone, to a high-pressure component, comprising a bore and a connection line in the high-pressure component, wherein the bore has an internal screwthread and the end face of the bore is joined to the connection line via a conical sealing cone, further comprising a hollow pressure screw with an external screwthread which is designed to engage in the internal screwthread of the bore, wherein the pressure screw has an internal screwthread which is designed so as to engage in the external screwthread of the sensor, wherein the external screwthread and internal screwthread of the pressure screw run in opposite directions, so that the sensor sealing cone and the end face of the bore can be pressed against each other by screwing the pressure screw into the bore of the high-pressure component.

Abstract: A method for controlling telecommunication services in a telecommunication network wherein both the telecommunication services that a service control point administers as well as the service switching points are allocated to specific network operators and an additional check of the network operator is proposed, which is implemented by the SCP before a service call is further-processed.
