Abstract

PURPOSE:To simultaneously execute the retrieval of incoming subscriber and the number identification of a subscriber number, by providing a count circuit of scanning pulses, in an incoming subscriber identification circuit of a radio telephone exchanger. CONSTITUTION:When an incoming call is given to subscriber circuits 11-1n, it is given to a scanning pulse generating source 2 via an incoming display lead (a) and given instruction to produce an output. While this output is transmitted to a scanning circuit 3 and becomes a scanning pulse to the subscriber circuits 11-1n, it is transmitted to a count circuit 7 to start the count. A subscriber circuit 1m receiving the incoming call receives a scanning pulse and transmits a signal to a lead d to stop the source 2 and the count of the circuit 7. The count value m of the count circuit 7 at this time is stored as the number of the circuit 1m.
