Zusammenfassung:The invention relates to a PCM switching system employing switching elementary matrix controlled by a control microprocessor ( mu P). Each elementary matrix including: one block for the control of incoming flows (BP_GFE) suitable to receive flows whose bit-rate is preferably separately programmable; one programming and control block for outgoing flows (BP_GFU) suitable to make available at output those flows whose bit-rate is preferably separately programmable; one connection control block (BCC) suitable to ciclically and constantly control the correctness of the connection operations; one timing receipt and distribution block (BR_DT), one synchronism phase shifting detection block (BRSS), one microprocessor interface block (BIM).
