   Diese Anordnung hat gegenüber der erstgenannten noch den Vorteil, dass für die Auslösung der eingeschalteten Wähler des Sprechweges und Belegung eines anderen Wählersatzes bedeutend mehr Zeit vorhanden ist, als wenn die Auslösung des Sprechweges erst nach dem Auslösen des   Impulswähh'rs erfolgen würde.

   Earth switches on in a holding circuit, the pulse selector switches on again, which adjusts the reset selector, which is now occupied by a preselector IIVW '.



   This arrangement has the advantage over the first mentioned that there is significantly more time for the activated dialer of the speech path to be triggered and for another dial set to be activated than if the speech path were only released after the impulse dialer had been triggered.



   In the embodiment shown, the creation of a spech path is repeated for as long as the test current cycle does not occur. than the calling tell

 Stepping mechanism the device is made that the number of repetitions is determined. After the last attempt, the relay chain or the step-by-step switch can prevent the triggering again and a monitoring control can be switched on for the office staff so that they can determine the cause of the faulty connections.
