Abstract

A central for telecommunication, namely, a centrally controlled central operating in tdm mode, characterized in that the peripheral units comprise first elements to recognize the control and signaling telegrams sent from the central control to the unit itself, second elements to recognize a criterion of pre-blocking in telegrams to pre-block all lines that may have incoming traffic, and third elements to detect a transmission failure of the telegram for a time greater than a first period of time, in order to pre-block, independently, all lines that may have incoming traffic; these pre-processors are located between the controlled units and the central control; each pre-processor provides routine telegrams to several controlled units. In each pre-processor there are first storage elements, for each output control channel, to store the operating mode of each individual channel; in each pre-processor there are second storage elements to store the operating mode of the pre-processor. The first and second storage elements are controlled by the central control, and there are logical elements to combine the logical conditions of the two storage elements.
