Claims (1)

PATENT-ANSPRUCH : Schaltungsanordnung für Wahlanruf bei Trägerstromverbindungen, bei denen der Sendestrom durch die Signalströme selbst, z. B. Sprechströme, gesteuert wird, insbesondere für den Verkehr über Starkstromleitungen, dadurch gekennzeichnet, dass die Beendigung des Wahlanrufes seitens der rufenden Station dort mit Hilfe von Wählern oder geeigneten Schaltmittel selbsttätig besonders gekennzeichnet wird, um das Gerät von der Rufbereitsehaft in die Sprechbereitschaft überzuführen. EMI2.1 PATENT CLAIM: Circuit arrangement for dial-up calls with carrier current connections in which the transmission current is caused by the signal currents themselves, e.g. B. speech currents, is controlled, especially for traffic over power lines, characterized in that the termination of the dialing call on the part of the calling station is automatically identified there with the help of voters or suitable switching means in order to transfer the device from call readiness to ready-to-speak.
