ABSTRACT:
In a telecommunications switching system having a central processor for generating control signals, peripheral units, and a power source terminal, a power control arrangement includes a plurality of power switches for selectively connecting and disconnecting the peripheral units and the power source terminal in order to minimize power consumption. Responsive to peripheral unit control signals, a power control unit, which is included in the arrangement, controls the operation of the power switches so that only those peripheral units designated by a control signal are connected to the power source terminal. After the peripheral units have been operated, the power control arrangement disconnects the operated peripheral units from the power source terminal.
