Abstract

PURPOSE:To answer by adding inherent information of a network control device to an AC answer signal in case the AC answer signal is transmitted from an AC answer signal transmitting circuit when the start signal receiving circuit of a network control device receives a start signal from a central device. CONSTITUTION:A telephone number of a network control device 113 is sent to a telephone switchboard 112 from a central device 111. When the switchboard 112 receives the telephone number, a line 102 is started. Then a start signal receiver 211 in the device 113 receives a network control device starting signal, and a transmitter 214 in the device 113 is started. The transmitter 214 transmits an answer signal to a line 201. In this case, an information input 205 inherent to the device 113 is added to the answer signal to be sent to the device 111 from the transmitter 214. The device 111 discriminates the inherent information 205 to confirm a connection between the central control device and the network control device 113.
