fixed telephone station releasably attach. The releasable connection is advantageously designed so that on the side of the releasable connection the device has a socket and the connecting cord has a plug.

The operating switchover can be carried out in a simple manner in that a switching device in the socket can be actuated via the plug, which controls the switching on and off of the radio transmission devices and initiates the necessary switching s in the stationary telephone station. '.... ■

The invention is based on a schematic in the drawing illustrated embodiment of a Telephone subscriber station explained in more detail.

The fixed telecommunication station XIn-St let over the connection line is connected to the office and contains all the parts necessary for setting up and processing of a call are required, as a normal telephone subscriber parts. One and only The difference is that the connection cord to the handset with the microphone M and the! Remote receiver 1 is solvable on one side. As shown in the exemplary embodiment, the connecting cord can be attached the fixed Pernsprechstation TIn- ^ St solved will. The fixed telephone station! DIn-St carries a corresponding multi-pole Steek socket VB and the connecting cord a matching one multi-pole connector VSt.

In the socket VB is a switching device, which when inserting and removing the connector VSt is controlled. If the connector VSt

the switchover to wire. Handling of the conversation · The electroacoustic converters M and Έ of the handset are simply connected to the separate connections of the saber circuit provided in the fixed telephone station TIn-St. The ones in the, first solid. Pernsprechetatioa provided signal transmission devices are switched off or off.

If the connecting plug VSt is removed from the socket VB is pulled, then the wired connection is interrupted to eehnurloeen handset SH and ös must be switched to the point transmission equipment will. This' switchover takes again the Switching device in the socket VB. The send signals are attached to the four-wire sides of the hybrid circuits Receiving circuits of the air transmission lines switched on, whereby you from the fixed speaker Modulated carrier frequency emitted by Iln-St taken up by the connecting cable acting as antenna A and attached to the cordless handset feet ' will. Ba the connecting cord is multi-core and with both the receiving and sending circles of the echnurloaen handset sE is connected, The connecting cord can also be used as a transmitter ■ antenna for the cordless handset radiated modulated carrier frequency act.
