    The AMI code guarantees that transitions are always present before and after each mark (1 bit), but are missing between adjacent spaces (0 bits). To prevent loss of synchronization when a long string of zeros is present in the payload , deliberate bipolar violations are inserted into the line code, to create a sufficient number of transitions ...
