Key pulsing

In telecommunication, a key pulsing is 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 pulsing.
