Abstract:
A method of synchronizing the transmission of blocks of data from a transmitter to a receiver, said method comprising the steps of:generating and inserting a 2-bit cyclical sequential synchronization sequence into a header preceding each block of data; continuously cycling the value of said synchronization sequence wherein said synchronization sequence is incremented or decremented once for each block of data to be transmitted, the sequence being reset when a maximum or minimum value is reached; transmitting idle sync cells during the time said receiver attempts to synchronize with said transmitter; transmitting said blocks of data over a plurality of serial transmission links to a receiver; at said receiver, receiving data over said plurality of serial transmission links; multiplexing different groups of received data bits, each group representing a different framing position, wherein one of said framing positions is selected in accordance with a selection signal; searching data output of a current framing position for said 2-bit synchronization sequence; and if synchronization is not found, repeatedly selecting a different framing position via said selection signal and searching said received data for said 2-bit synchronization sequence.
