Verbindung genau wie bei der vorher beschriebenen Ausführungsform.
Beim Trennen einer bestehenden Verbindung durch die Trenntaste TR zwecks Umschaltens der Nebenstelle auf eine andere Amtsleitung wird bei der Schaltung gemäss Fig. 2 durch das über Kontakt 5 < ? erregte Relais G nicht nur die Sperrung der übrigen freien Amtsleitungen, sondern auch eine Sperrung der Einrichtungen der Nebenstellen durch Öffnen bzw. Schliessen der Kontakte 47, 48, 49 hervorgerufen. Durch gleichzeitiges Drücken der Nebenstellentaste wird dann wie bei den eben geschilderten Einstellvorgängen bewirkt, dass nur die Einrichtungen zur Wirkung kommen, durch welche die Verbindung der umzuschaltenden Nebenstelle auf die neue anrufende Leitung erfolgt.
Es sei noch bemerkt, dass in den dargestellten Schaltungsanordnungen bei abgehendem Verkehr die Verbindung einer anrufenden Nebenstelle mit einer Amtsleitung selbsttätig erfolgt.
Nimmt z. B. N2 in der Schaltung nach Fig. 2 seinen Hörer ab, so wird 'erregt und schliesst seinen Kontakt 54, wodurch D2 in Tätigkeit gesetzt wird, und 55, wodurch T2 an Erde gelegt wird. Findet dann der Wähler eine freie Leitung, so erfolgt die Anhaltung des Wählers in bekannter Weise. Diese Schaltvorgänge sind Ru die Erfindung ohne Bedeutung.
PATENT-ANSPRÜCHE :
1. Schaltungsanordnung für Fernsprechanlagen, bei denen die Verbindungen über selbsttätige Wähler unter Mitwirkung einer Beamtin hergestellt werden, nach Patent Nr. 70402, insbesondere für Post und Nebenstellenanlagen, dadurch gekennzeichnet, dass bei einem Ruf zu

der noch freien Amtsleitungen bewirkt wird.

EMI3.1
Connection exactly as in the previously described embodiment.
When an existing connection is disconnected by the disconnect button TR for the purpose of switching the extension to another exchange line, in the circuit according to FIG. 2 by the contact 5 <? energized relay G not only the blocking of the remaining free trunk lines, but also a blocking of the facilities of the extensions by opening or closing the contacts 47, 48, 49 caused. Simultaneously pressing the extension button then has the effect, as in the case of the setting processes just described, that only those devices come into effect through which the connection of the extension to be switched to the new calling line takes place.
It should also be noted that in the circuit arrangements shown, the connection of a calling extension to an exchange line takes place automatically in the case of outgoing traffic.
Takes z. B. N2 in the circuit of Fig. 2 from his receiver, so is' excited and closes its contact 54, whereby D2 is put into action, and 55, whereby T2 is connected to ground. If the voter then finds a free line, the voter is stopped in a known manner. These switching operations are irrelevant to the invention.
PATENT CLAIMS:
1. Circuit arrangement for telephone systems in which the connections are made via automatic voters with the assistance of an officer, according to Patent No. 70402, in particular for post and private branch exchanges, characterized in that when a call is made
