EMI3.1 1. Schaltungsanordnung für automatische Fernsprechämter mit selbsttätiger Fortschaltung des Wahlschalters auf einen freien Leitungskontakt und selbsttätiger Leitungsvorbindung durch eine gemeinsame Besetztkontrollvorrichtung, dadurch gekennzeichnet, dass der Anker (k) eines von der Bosetztkontrollvorrichtung (Kontaktann d) in bekannter Weise abhängigen Elektromagneten (i) und eine von der Bewegung des Wahlschalter (a) ab- hängige Kontaktvorrichtung (o, p, q) derart zusammenwirken, dass durch die Kontaktvorrichtung (o) des vom Teilnehmer aus in bekannter Weise in Gang gesetzten Wahlsehalters der Stromkreis einer Fortschaltevorrichtung (s, r, e) EMI3.1 1. Circuit arrangement for automatic telephone exchanges with automatic switching of the selector switch to a free line contact and automatic line pre-connection by a common occupancy control device, characterized in that the armature (k) one of the Bosetztkontrollvorrichtung (Kontaktann d) dependent in a known manner electromagnet (i) and a on the movement of the selector switch (a) dependent contact device (o, p, q) cooperate in such a way that the circuit of an incrementing device (s, r, e ) zur Wirkung auf den Wahlscbaltor gebracht und nach Erreichung eines freien Leitungskontaktes durch Wirkung der Bosetztkontrollvorrichtung (d) mittelst des Elektromagneten (i), welcher gleichzeitig die am Wahlschalter eingestellte freie Leitung mit der Teilnetimerleitung (tn, n) verbindet, für die Dauer des Gespräches ausser Wirkung gesetzt wird, während bei der Rückkehr des EMI3.2 desselben einerseits der Elektromagnet (i), andererseits die Fortschaltevorrichtung (s, r, e) in den Ruhezustand zurückversetzt (abgeschaltet) werden. brought into effect on the selector switch and after reaching a free line contact by the action of the set control device (d) by means of the electromagnet (i), which at the same time connects the free line set on the selector switch with the partial timer line (tn, n), for the duration of the conversation except Effect is set while on the return of the EMI3.2 of the same on the one hand the electromagnet (i), on the other hand the stepping device (s, r, e) are set back to the idle state (switched off). 2. Schaltungsanordnung nach Anspruch 1, dadurch gekennzeichnet, dass die Arbeitslage des über die Besetztkontrollvorrichtung (d) erstmalig erregten Elektromagneten (i) fUr die Daunr des Gespräches durch eine selbsteingeschaltete Haltewicklung (2) aufrecht- EMI3.3 2. Circuit arrangement according to claim 1, characterized in that the working position of the electromagnet (i), which is excited for the first time via the occupancy control device (d), is maintained for the continuation of the conversation by a self-switched holding winding (2).
