Abstract

A control set for synchronizing computers that control switching meshes for at least two systems, including at least two control devices, each associated with one of the systems, and each of them including a local generator to generate first signals that control the associated system and second signals that are transmitted to the other control device (s). Each control device includes logical elements that, when receiving a second signal, intervenes in the control of the associated system. Characterized in that the logical elements of each control device make it possible for a second signal (SYNC'1) to be received to intervene in the control of the system associated with said control system, instead of a first locally generated signal (CRO1), when said second signal (SYNC'1) is received within a predetermined time interval before a first signal (CRO1) is generated locally.
