Abstract

PURPOSE:To enable to identify the transmitting party by the central system, by transmitting a series of block information in combination with data code, specific identification code, and control code, at the telephone network data entry terminal. CONSTITUTION:The transmission data is contained in memory by operating the keyboard 2 to transfer the data to the microcomputer 1. This data is also displayed on the display unit 3. Next, when the transmission instruction key on the keyboard 2 is depressed, the code corresponding to the data, specific identification code from the identification code production circuit 4, and control code representing the end of transmission data are transferred from the microcomputer 1 to the audio signal production circuit 5 as a series of block information. The audio signal production circuit 5 convertrs the block information into audio signal, feeds an output to the audio coupler 6, and the block information is transmitted to the central system from the telephone transmitter.
