   wird wechselweise geladen und entladen und begünstigt die Erzeugung der Sprechströme in der Wicklung a6. Es erfolgt hiedurch eine erhöhte Lautwirkung im Hörer a. Der rhei ! nehmer mnss jedoch auf den Knopf l drücken, um sein Mikrophon benutzen zu können. Durch Niederdrücken des Druckknopfes l wird der Arm m unter den Hakes j des Ankers kl geschoben, so dass der um das Mikrophon gelegte Nebenschlusstromkreis geöffnet wird und der Apparat der Theilnehmerstation numehr ungehindert benutzt werden kann. 



  Der Verlauf der Sprechströme ist nun der gleiche, wie oben beschrieben, mit der

 lauf tritt und der Teilnehmer nunmehr in der Lage ist, Stromschwankungen durch das Mikrophon auf der   Leitung 1, 2 zu erzeugen.   



   Nachdem der Beamte des Vermittlungsamtes den Wunsch des anrufenden Theilnehmers entgegengenommen hat, stellt er die Verbindung in der   üblichen   Weise her und

Wenn der anrufende Theilnehmer den Beamten des Vermittlungsamtes nochmals anrufen will, bevor die Stöpselleitung des Vermittlungsamtes unterbrocheu ist, muss cr den Umschalthaken in auf- und niederschwingende Bewegung versetzen, um das Überwachsungssignal i in Thätigkeit zu setzen. 



   Wenn die mit dem Gesprächszähler versehene Theilnehmerstation von einer anderen Station angerufen wird, wird die Verbindung durch den Verbindungsstöpsel f' hergestellt, der in die Klinke e gesteckt wird. Dann ist die Batterie   b   mit der Linienleitung 1, 2 in umgekehrter Weise verbunden, wie vorhin, so dass durch das polarisierte Relais k die

However, the user must press the l button to use his microphone. By depressing the pushbutton l, the arm m is pushed under the hook j of the anchor kl, so that the shunt circuit around the microphone is opened and the apparatus of the subscriber station can no longer be used without hindrance.



  The course of the speech streams is now the same as described above with the

 running occurs and the participant is now able to generate current fluctuations through the microphone on the line 1, 2.



   After the official of the switching office has received the request of the calling subscriber, he sets up the connection in the usual way and

   If the subscriber station provided with the call counter is called by another station, the connection is established through the connecting plug f 'which is inserted into the jack e. Then the battery b is connected to the line line 1, 2 in the reverse manner as before, so that through the polarized relay k the
