PURPOSE:To attain external display by adding a communication amount detecting part to a communication processor so as to detect the communication amount of each line. CONSTITUTION:A timer 8 sets a desired start and stop time, a detection circuit 9 detects a transmission control code of each line from a communication control part 3, a measuring circuit 10 measures an operating time of each line and accumulates it to a register 11. An operating circuit 12 operates the utilizing rate of each line based on the set time from the timer 8 and the accumulated operating time from the register 11 and the result is displayed on a display circuit 13 so as to detect the communication amount of each line within a prescribed time and display it externally. |
