Abstract

A method of protection against false connections in telecommunication exchanges, where the exchange operates digitally and in TIM mode, under central control, especially programmed central control. Characterized in that, each command from the central control to a controlled unit, contains, in addition to the address of the element to be controlled and the corresponding information, additional information that indicates the expected situation of the routed element, before the order comes into operation. . After the arrival of said order to the unit to be controlled, the actual situation is compared with that expected and contained in the order. The execution of the order depends on the conformity of the two situations. (Machine-translation by Google Translate, not legally binding)
