Bei der Schaltung nach Fig. 2 wird als Rufströmquelle ein Induktor 07 verwendet, dessen Achse sich bei ihrer Drehung in der Längsrichtung (auf der Zeichnung beispielsweise nach rechts) verschiebt.

   Die Schaltung nach Fig. 3 unterscheidet sich von der zuletzt beschriebenen nur dadurch, dass das   Überwachungssignal   L und das Überbrückungsrelais M nicht in das Schnursystem, sondern in die Amtsauschlussleitung 3, ,, u. zw. vom Amte aus gerechnet vor die Klinke Q eingeschaltet sind. 



   Die neue Schaltung könnte auch in der Weise ausgeführt werden, dass kein besonderer   Rufschlüssssl   in dem Schnursysteme vorhanden ist und ein entsprechender Schalter in die zu dem Teilnehmer N führenden Leitungen eingesetzt wird.

 the office continues to be energized .. As soon as the subscriber N reports, the anchor of the monitoring signal L on the main unit leaves its break contact b and thereby interrupts the bridge between the speech lines 7, 8,
In the circuit according to FIG. 2, an inductor 07 is used as the Rufstromquelle, the axis of which moves in the longitudinal direction (for example to the right in the drawing) when it is rotated.

 09, 08, M a bridge is formed between the voice lines 7, 8, which is maintained even after the call has ended because the bridging relay M picks up its armature and thereby forms a shunt to the contacts 09 and the spring 08 in conjunction with its normally open contact.



   The circuit according to FIG. 3 differs from the last described only in that the monitoring signal L and the bridging relay M are not in the cord system, but in the trunk exclusion line 3, ,, u. betw. calculated by the office before the latch Q are switched on.



   The new circuit could also be implemented in such a way that there is no special Rufschlüssssl in the cord system and a corresponding switch is used in the lines leading to the subscriber N.
