Abstract
A centrally controlled telephone switching system distributor including: various components distributed in groups and controlled, as follows, from a central unit; first coupled recording means for receiving and storing address data from the central unit; coupled second recording means for receiving and storing control data from the central unit; third recording means coupled to receive control data from the central unit specifying the states to be adopted by one or more components of a group; fourth recording means provided to receive inhibition data designating components whose state is to remain unchanged; coupled masking means for receiving the control and inhibit data from the respective third recording means and the fourth recording means for providing masking signals for masking the elements of the control data item corresponding to components whose state is to remain unchanged, said masking means providing additional signals to control other components whose state is to be changed, thus limiting the function of the control unit, to the elaboration and transmission only of the control data elements destined for some of the components of the group. to which they have been directed.
