Anlage zur Weiterschaltung eines auf einer ersten Anschlußleitung ankommenden Anrufes über eine zweite Anschlußleitung an einen anderen Fernsprechanschluß

Calls on an incoming line (1) are forwarded on an outgoing line (2) to another subscriber at the same or a different location, via a signal-transmission, DC-level-setting and telephone-connection-matching circuit (5). A controller (6) connected between the two ringing-tone recognition circuits (4,4a) also operates a DTMF transmitter (S), and allows insertion of recorded speech, electronic music or other sounds. Loop currents on both incoming and outgoing lines are detected by suitable circuits (8,8a). ADVANTAGE - The appts. can be connected and used by any private telephone subscriber at usual rates for call forwarding, even at cheap rate.
