   man   es auch mit nur einer Wicklung versehen, die der einen Anrufrelaiswicklung im entsprechenden
Leitungszweige parallel geschaltet wird ; in diesem Falle ist   natürlich auch   nur eine   Gegenwicklung   erforderlich. 



   PATENT-ANSPRÜCHE : 
1. Schaltung für   Fernsprechämter,   bei denen eine selbsttätige Rufvorrichtung beim Melden des Teilnehmers durch eine während der Rufdauer an der Sprechleitung liegende Vorrichtung ausser Wirkung gesetzt wird, dadurch gekennzeichnet, dass zur Einleitung der Abschaltvorgänge ein Relais   (12)   dient, das beim Stöpselstecken dem Anrufrelais (AR) des verlangten Teil- nehmers (T) parallel geschaltet und durch beim Rufen eingeschaltete Gegenwicklungen   (19, 20     zu 11, 14)   am Ansprechen während der Rufstromgabe verhindert wird.

   it is also provided with only one winding, that of the one call relay winding in the corresponding
Branch lines are connected in parallel; in this case, of course, only one reverse winding is required.



   PATENT CLAIMS:
1. Circuit for telephone exchanges, in which an automatic call device when reporting the subscriber is put out of action by a device lying on the voice line during the call duration, characterized in that a relay (12) is used to initiate the shutdown processes, which the call relay when plugging in (AR) of the requested subscriber (T) is connected in parallel and is prevented from responding during the ringing by switching on counter windings (19, 20 to 11, 14) when calling.

Claims (1)

2. Schaltung nach Anspruch 1. dadurch gekennzeichnet, dass die Gegenwicklungen (19, 20) gleichzeitig mit der Anschaltung des Rufstromes über Kontakte (16, 17) am Rufrelais (9) ein- geschaltet werden. 2. Circuit according to claim 1, characterized in that the counter-windings (19, 20) are switched on simultaneously with the connection of the ringing current via contacts (16, 17) on the ringing relay (9).
