Abstract

PURPOSE:To shorten the key input time, by converting a sentence inputted by key groups to combinations of pushphone dial tones and by sending them to a control part to match standards of the signal to those of the receiving side and transmitting a selected pushphone dial tone signal. CONSTITUTION:A changeover switch 4 is switched to the calling side to input the number of the other-party station by numeric keys similarly to an ordinary pushphone. For this numeric input, a signal of combinations of frequencies is transmitted from a pushphone dial tone generator 5 to a line and is connected to the other-party station through an exchange. When the other part answers, the switch 4 is switched to the sentence side, and a sentence is inputted by a key group 1. This signal is converted to combinations of pushphone dial tones and is inputted to a control part 3. The control part 3 matches the transmission time and the interval of the signal to standards of the receiving side and inputs the signal to the generator 5, and the generator 5 generates a selected pushphone dial tone signal and transmits it to the line.
