Abstract
The disclosed invention relates to a re-synchronization system that operates in a switching arrangement receiving a plurality of incoming data packets. The switching arrangement is made of an active switch card that transmits the incoming data packets and a backup switch card that may be re-activated by an operator after replacement. The re-synchronization system is implemented in each switch card. When the backup switch card is re-activated, both switch cards receive the incoming data packets and the system of the invention allows to re-synchronized both switch cards by controlling the transmission of the incoming data packets out of each switch card until the same data packets are transmitted. The re-synchronization system further comprise storage for storing the incoming data packets and detector for detecting a re-synchronization information among the incoming data packets.
