First, when a bell signal is input from a plurality of terminal devices 50, 80, and 90 (S1), the main controller 10 receives the call in response to the bell signal and receives data transmitted from the outside according to the call. The counterpart ID number is detected from the transmitted data to determine whether the signal is transmitted from the terminal control apparatus 50 (S2).

After receiving the predetermined data transmitted from the terminal controller 50 (S3), the main controller 10 retransmits the received data to the terminal controller 50 (S4), the terminal controller ( 50 compares the transmitted data with each other and transmits a confirmation signal to the main controller 10 (S5). That is, the terminal control device 50 receives the transmitted data to check whether there is an error in the transmitted data, and confirms whether there is an error, and then transmits a confirmation signal to the main controller 10, and together with the confirmation signal the main controller ( 10 stores the transmitted data in the memory 21.

The main controller 10 receives data transmitted from the terminal control apparatus 50, compares and analyzes the contents of the input data with a preset data protocol, and then determines what kind of information is received. When the end signal is input from the control device 50, the transmitted data is output as image 13, text 15, or voice 17 data (S6).

If a bell signal is not input from the outside in the first step S1, it is determined whether a key signal for inputting a predetermined command is detected from the external input means 11 of the main controller 10 (S7).

The main controller 10 selects a reception ID number of the specific terminal control apparatus 50 according to the key signal input, and inputs specific command data to be transmitted to the terminal control apparatus 50 in the form of a dial tone multi-frequency method. Received and generated (S8).
