ABSTRACT:
A system and a method for synchronizing running disparity values in a first computer and a data demapping device are provided. The method includes generating a plurality of data characters and a synchronization control character. The method further includes iteratively determining a first running disparity value based on each character of the plurality of data characters and the synchronization control character. The method further includes encapsulating a first plurality of data characters and the synchronization control character from a computer into at least one GFP data block and transmitting the GFP data block to data demapping device. The method further includes decoding the GFP data block to obtain the plurality of data characters and the synchronization control character and iteratively determining a second running disparity value based on each character of the plurality of data characters and the synchronization control character. The method further includes setting the second running disparity value in the data demapping device equal to either a positive running disparity value or a negative running disparity value based on the synchronization control character to synchronize the second running disparity value and the first running disparity value.
