Abstract
Letters and a space are assigned to numeric keys of a pushphone. A desired numeral, letter or space is transmitted by depressing a corresponding numeric key a predetermined number of times, and thereafter a specific symbol key is depressed. At a reception side, a transmitted letter is detected in accordance with the corresponding numeric key code and the data representing the number of times of depression of the corresponding numeric key. An alphanumeric character string is thus displayed.
