 bei n"l an die Zuleitung zur Gruppe II angeschaltet, so dass die Gruppe I gesperrt ist. Somit erfolgt beim Freisein von weiteren Verbindungsleitungen V ein Anlaufen der auf die besonderen Kontaktsätze a, b, c eingestellten Wähler der Gruppe II usw. 



   Nach dem Anlaufen aller Wähler der letzten Gruppe wird ein Relais M über Erde, g, g1 > M, Batterie, Erde erregt, welches die Haltestromkreise der Relais N an den Kontakten   M, m...   unterbricht und dadurch das Anlaufen von Wählern in der Gruppe I wieder ermöglicht. 



   PATENT-ANSPRÜCHE :   1.   Schaltungsanordnung für Fernsprechvermittlungsämter mit selbsttätigen Wahlschaltern nach Patent Nr. 48368 bzw. Nr. 60877, bei welchen ein Wiederanlaufen der auf einen besonderen Kontaktsatz eingestellten Wahlschalter beim Freiwerden von ihnen zugänglichen Verbindungsleitungen durch besondere Schalteinrichtungen bewirkt wird, gekennzeichnet durch ein den Wahlschaltern oder Gruppen von Wahlschaltern zugeordnetes besonderes Schaltorgan (Relais Y), durch welches eine Einwirkung der   Umachalteeinrichtung     (R,   h) auf Wahlschalter, auf denen kein Mehranruf liegt, verhindert wird.

 EMI3.1
 when n "1 is connected to the supply line to group II, so that group I is blocked. Thus, when further connecting lines V are free, the selectors of group II etc. set to the special contact sets a, b, c are started.



   After all voters in the last group have started up, a relay M is energized via earth, g, g1> M, battery, earth, which interrupts the holding circuits of relay N at contacts M, m ... and thereby starts up voters in the Group I enabled again.



   PATENT CLAIMS: 1. Circuit arrangement for telephone exchanges with automatic selector switches according to patent no. 48368 or no. 60877, in which a restart of the selector switches set to a special contact set is caused by special switching devices when they are accessible connecting lines, characterized by a Special switching device (relay Y) assigned to selector switches or groups of selector switches, which prevents the changeover device (R, h) from affecting selector switches on which there is no multiple call.

Claims (1)

2. Schaltungsanordnung nach Anspruch 1, dadurch gekennzeichnet, dass durch die Schaltorgane (Relais Y), die bei der Einstellung der Wahlschalter auf den besonderen Kontaktsatz (a b, c) zur Wirkung gebracht werden, die Umschaltung bei der Belegung der von diesen ausgehenden Hilfsleitungen vorbereitet wird. 2. Circuit arrangement according to claim 1, characterized in that the switching elements (relay Y), which are brought into effect when setting the selector switch on the special contact set (from, c), prepare the switching when the auxiliary lines are assigned becomes. 3. Schaltungsanordnung nach Anspruch 2, dadurch gekennzeichnet, dass durch die Schaltorgane (Relais Y) bei ihrem Ansprechen ein Wiederanlaufen von ihren zugehörigen Wahlschaltern in der Reihenfolge nachgeordneten Wahlschaltern (Unterbrechung der betreffenden Erreger- stromkreise der Relais U) verhindert wird. 3. Circuit arrangement according to claim 2, characterized in that the switching elements (relay Y) when they respond, a restart of their associated selector switches in the sequence downstream selector switches (interruption of the relevant excitation circuits of the relay U) is prevented. 4, Schaltungsanordnung für Fernsprechvermittlungsämter mit selbsttätigen Wahlschaltern nach Patent Nr. 48368 bzw. Nr. 60877. dadurch gekennzeichnet, dass beim Wiederanlaufen eines Wahlachalters oder einer Gruppe von Wahlschaltern seine oder ihre Sperrung erfolgt (Relais N1, N2) welche nach dem Anlaufen aller in der Reihenfolge nachgeordneten Wahlschalter oder Gruppen von Wahlschaltern aufgehoben wird (Relais M). 4, circuit arrangement for telephone exchanges with automatic selector switches according to patent no. 48368 or no. 60877. characterized in that when a Selector switch or a group of selector switches his or her blocking takes place (relay N1, N2) which is canceled after all selector switches or groups of selector switches arranged in the sequence have started up (relay M).
