Abstract

PURPOSE: To eliminate the unnecessary call time and thus prevent the unnecessary consumption of the battery by sending the output of the ringing tone detector to the timer and then displaying the count value on the display unit.
CONSTITUTION: When the connection is over to the base station, dial 23 and receiver 13 are connected to transmitter 16 and telephone receiver 15 respectively via switch 17. And the ring-back tone is given to receiver 15 as well as to ringing tone detector 24 when the dial is over. The ring-back tone is sent to delay circuit 30 through BPF25 and then extinguished by the answer given from the remote side. Then the output of comparator 31 is raised with reduction of the output of circuit 30, and timer 34 is actuated via FF32 to display 35 the count value. In this way, the unnecessary call time can be eliminated, at the same time preventing the unnecessary consumption of the battery.
