Abstract

PURPOSE:To absorb inconformity of a speed between different-speed terminal equipments, by mutually exchanging the signals showing a communication speed of a transmission terminal and a receiving terminal prior to communication between the terminals, and converting a communication speed to that which has been decided in advance. CONSTITUTION:A calling signal (a) of the terminal equipment 1 is sent to the line switching network 3 through the communication speed converter 2. As a result, a call signal is sent to the terminal equipment to be called 5 through the communication speed converter 4. Also, a designating signal (g) of a communication speed S1 of the terminal equipment 1 is sent to the communication speed converter 4 from the communication speed converter 2, and also a designating signal of a communication speed S2 of the terminal equipment 5 is sent to the communication speed converter 2. After that, communicable signals f1, f2 are sent to the terminal equipments 1, 5, and a mutual communication (i) is executed between different-speed terminal equipments 1, 5.
