Durch Schliessen von Kontakt IV wird der Impurstromkreis geschlossen. Die Einstellung der Wähler geschieht in bekannter Weise durch Unter-   brechung   der Leitungsschleife am Kontakt V. 



   Mittlerweile hat die Abfragebeamtin den Stöpsel 19 in die Klinke    eingeführt. Dadurch   wird ein Stromkreis über die Ader 21 und das Relais C geschlossen, welches durch öffnen des Kontaktes 22 den   Stromkreis der Lampe 14 unterbricht.

  Dieses legt die Anker 34 und 35 um und bewirkt dadurch einen   Stromfluss   über die Sprechadern zum Schnurstromkreis der Abfragebeamtin. Relais R2 spricht an und öffnet Kontakt 36, wodurch die Lampe SL"erlischt. Dies dient der Abfragebeamtin als Zeichen für die Meldung des verlangten Teilnehmers. 



   Nach Schluss des Gespräches hängen beide Teilnehmer ihre Hörer auf. Bei Anhängen an der Station des Anrufenden wird R1 stromlos. Dadurch wird über 8   und 24 die Schlusslampe SL'   eingeschaltet, ferner wird am Kontakt 37 der Strom über die Ader 28 unterbrochen. Relais T des Vorwählers fällt ab und schaltet über 7 und Kontakt   38,   der beim ersten Schritt des Vorwählers geschlossen wurde, den Drehmagneten D ein. Beim Erreichen der Ruhelage wird Kontakt 38 geöffnet und der Vorwähler bleibt stehen. Hängt der Angerufene an, so fallen   A   und B ah, dadurch auch U.

 Relay T2 energizes, which at 17t and 18t2 disconnects the calling side and prevents impulses from being transmitted there. Closing contact IV closes the pulse circuit. The setting of the voters is done in a known way by breaking the line loop at contact V.



   In the meantime the interrogator has inserted the plug 19 into the handle. As a result, a circuit is closed via the wire 21 and the relay C, which interrupts the circuit of the lamp 14 by opening the contact 22. This serves as a sign for the liaison officer that the connection line jack has been plugged. It also prepares relays

   After setting all voters, contact III is opened, T2 drops out and switches the speech wires through. Contact 11 is closed and thereby closes the circuit for the

 (Fig. 2). They close the circuit for a changeover relay U via contacts 32 and 33.



  This moves the armature 34 and 35 and thereby causes a current to flow over the voice wires to the cord circuit of the interrogator. Relay R2 responds and opens contact 36, whereby the lamp "SL" goes out.



   When the conversation is over, both participants hang up their phones. When attaching to the station of the calling party, R1 is de-energized. As a result, the tail lamp SL 'is switched on via 8 and 24, and the current via wire 28 is interrupted at contact 37. Relay T of the preselector drops out and switches on the rotary magnet D via 7 and contact 38, which was closed during the first step of the preselector. When the rest position is reached, contact 38 is opened and the preselector stops. If the called party is connected, A and B ah fall, thereby also U.

   It is now assumed that the connection officer notices while the impulse is being given that she has made a mistake in setting the encoder. She then presses the immediately
