Abstract
The present invention provides a system and method for enabling the synchronization of a switch and an interface device. Based on a comparison of cell sequence numbers included in cells received from the interface device to a current cell time within the switch, cell time adjustment information can be transmitted to the interface device. The cell time adjustment information is used by the interface device to determine the cell sequence number that is included in cells transmitted to the switch.
