Abstract

PURPOSE: To prevent the call out tone from being transmitted to the caller until the ring trip relay is operated, by making earlier the call out signal transmission time to the called party and delaying the call tone to the caller, in an automatic exchanger system.
CONSTITUTION: In the telephone exchanger system having the call out signal transmission functions to the subscribers such as incoming trunk ICT and automatic station trunks, the relay FR which restores slowly with the operation of the relay G of the caller side is provided to the incoming trunk ICT. While the relay FR slowly restores, the call out signal is transmitted to the subsequent station outgoing trunk OGT-L and the ring trip relay F is operated with the cell connected to the first winding of the relay A in the trunk OGT-L to restore the relay G by interrupting the operation circuit of the relay G with the relay F. Further, the call out signal delivery time to the called party to the incoming trunk ICT is made earlier and the call tone to the caller is delayed.
