Abstract:
1. A method for synchronizing cell times between a switch and an interface device, comprising: receiving a first cell at said switch from said interface device, said first cell including information identifying a first cell sequence number; comparing said first cell sequence number to a value of a cell sequence counter within said switch, defining a comparison; transmitting a second cell to said interface device, said second cell including counter adjustment control information that is based on said comparison, wherein said counter adjustment control information is used by said interface device to determine a second cell sequence number that is included in a third cell; and transmitting said third cell from said interface device to said switch, with said second sequence number being based on a value of a cell sequence counter within said interface device, said value of said cell sequence counter within said interface device being adjusted at least one cell time increment by said counter adjustment control information.
