Abstract

PURPOSE:To decrease the necessary number of signal lines between a signal line and a network control device, and t easily discriminate a dial information, by transferring a dial number in series, and also transmitting a number request signal by a signal line for transmitting the dial information. CONSTITUTION:One signal line 12 for transmitting a dial information is provided between a control device 11 and a network control device 10, the signal line 12 is made a high level, and a number request signal is sent out from a number request signal send-out part 17. A pulse which has been received when this requst signa is being sent out is counted by a counter 15. Also, the number request signal from the signal line 12 is detected by a dial information send-out part 19 of the control device 11, the dial number is sent out in series to the signa line 12 by a pulse which makes the signal line 12 a low level, and the dial information is transmitted to every digit when the number request signal is being sent out. These controls are executed by controlling circuits 16, 18, the necessary number of the signal lines 12 between the controlling device 11 and the device 10 is decreased, and the dial information is disciminated exactly.
