key pulsing
A system of sending telephone calling signals in which the digits are transmitted by operation of a pushbutton key set. Note: The type of key pulsing commonly used by users and PBX operators is dual-tone multifrequency signaling. Each pushbutton causes generation of a unique pair of tones. In military systems, pushbuttons are also provided for additional signals, such as precedence. Synonym yypulsing.
