und dergleichen, vornimmt. Vorzugsweise hat die Erfindung eine Anordnung zum selbsttätigen Anruf einer Teilnehmerleitung nach deren Belegung seitens des Leitungswählers zum Gegenstande.
Bisher war es üblich, den selbsttätigen Anruf eines Teilnehmers in der Weise zu bewirken, dass nach Auftreffen der Wählerschaltarme auf die gewünschte Teilnehmerleitung ein Rufrelais unter Strom gesetzt wurde, das die Rufstromquelle über Arbeitskontakte seines Schaltankers

and the like. The subject matter of the invention is preferably an arrangement for automatically calling a subscriber line after it has been occupied by the line selector.
Up to now it has been customary to initiate an automatic call from a subscriber in such a way that, after the selector arms hit the desired subscriber line, a call relay was energized, which the call current source via working contacts of its switch armature

After a single call, the control switch can be advanced to another position, with arms connected to the subscriber lines being placed on contacts to which the upstream source is periodically applied.
