 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 
 EMI3.2 
 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
 EMI3.2
 the trunk lines that are still free.

 

Claims (1)

2. Schaltungsanordnung nach Anspruch l, dadurch gekennzeichnet, dass gleichzeitig mit der Sperrung der Amtsleitungen eine Sperrung (Kontakte 47, 48) der nicht gewünschten Nebenstellen bewirkt wird (Fig. 2). EMI3.3 gewünschte Nebenstelle aufgehoben wird (Kontakt 56). 2. Circuit arrangement according to claim l, characterized in that, at the same time as the trunk lines are blocked, a blocking (contacts 47, 48) of the undesired extensions is effected (Fig. 2). EMI3.3 desired extension is canceled (contact 56). 4. Schaltungsanordnung für Fernsprechanlagen nach Patent Nr. 70402, insbesondere für Post- und Nebenstellenanlagen, dadurch gekennzeichnet, dass nach dem Zusammenfallen einer bestehenden Verbindung die in der Verbindung gewesene Amtsleitung durch Verzögerungeinrichtungen (VS) noch einige Zeit gesperrt bleibt (Kontakt 41), so dass während dieser Zeit keine Verbindung mit der Amtsleitung hergestellt werden kann. 4. Circuit arrangement for telephone systems according to Patent No. 70402, in particular for Post and private branch exchanges, characterized in that after an existing connection has collapsed, the exchange line that was in the connection remains blocked for some time by delay devices (VS) so that no connection can be established with the exchange line during this time. 5. Schaltungsanordnung nach Patent Nr. 70402, insbesondere für Post-und Nebenstellen- anlagen, dadurch gekennzeichnet, dass die Einrichtung (TR) zum Trennen einer bestehenden Verbindung zwecks Umschaltung der in der Verbindung befindlichen Nebenstelle auf eine andere EMI3.4 Nebenstelle nur diese Nebenstelle und die zur Besetzung vorbereitete Amtsleitung für die Ver- ) bindung freigegeben werden (Kontakte 50 und e). 5. Circuit arrangement according to patent no. 70402, in particular for post office and private branch exchanges, characterized in that the device (TR) for separating an existing one Connection for the purpose of switching the extension in the connection to another EMI3.4 Extension only this extension and the trunk line prepared to be occupied can be released for the connection (contacts 50 and e).
