Abstract

PURPOSE:To transmit some information to a communicating opponent with the change of the frequency of a ringing tone signal by generating the ringing tone signal of a different frequency when a frequency change signal is received from a frequency control means and sending the ringing tone signal through a communication line network to the communication terminal equipment of a dial number. CONSTITUTION:The titled device equipps a control signal generating 1 to output a control signal to a line by prescribed operation, a frequency control means 8 to output the frequency change signal when the control signal is received through a communication line network 3 and a ringing tone generating device 50 to generate the ringing tone signal of a first frequency when a signal to express the dial number is received through the communication line network 3 and to generate the ringing tone signal of a second frequency when the frequency change signal is received from the frequency control means 8. Thus, the frequency of the ringing tone signal is changed by the prescribed operation and some information can be transmitted by the ringing tone signal.
