Abstract

PURPOSE:To secure a clear and simple setting and display of the signals by connecting the terminal corresponding to each figure to each number input of the dial pulse sending circuit via several units of digital switches. CONSTITUTION:Digital switches SW1-SW11 connect the terminal corresponding to each figure to the input terminal of each number of dial pulse sending circuit D. While digital switch SW12 connects the common terminal to the end input terminal of circuit D and then connects the terminal corresponding to each figure to the sweep input terminal. Thus, the digital switches are used at the telephone number setting part in order to secure a clear and simple setting and display for the signals.
