digital switch
A switch that performs time-division-multiplexed switching of digitized signals.
Note 1: When used with analog inputs, analog-to-digital and digital-to-analog conversion are required. These functions may be performed by the digital switch.
Note 2: Implementation is accomplished by the interchange of time slots between input and output ports on a sequential basis under the direction of control systems. The control systems may be automatic, semiautomatic, or manual.
