Claim:
1. A method for seamless addition of new high bandwidth lanes, comprising: exchanging indications between first and second devices about adding the new high bandwidth lanes; wherein during the exchanging of the indications, the first device sends data to the second device using 8b/10b code words with a fixed delay over at least one first-to-second (f2s) active high bandwidth lane, the second device sends data to the first device using 8b/10b code words with a fixed delay over at least one second-to-first (s2f) active high bandwidth lane, and the new high bandwidth lanes are off; wherein adding the new high bandwidth lanes is to be done smoothly and without interrupting the fixed delay transmissions over the f2 s and s2f active high bandwidth lanes; sending, by the first device, an idle sequence using 7b/10b code words over the new high bandwidth lanes in parallel to continuing to send and receive the 8b/10b data with a fixed delay over the f2 s and s2f active high bandwidth lanes; sending, by the first device over the at least one f2 s active high bandwidth lane, a synchronization sequence during an inter packet gap; and further comprising sending by the first device, over the new high bandwidth lanes and in parallel to a predetermined point within the synchronization sequence, a known non-idle sequence; utilizing, by the second device, the known non-idle sequence for deskewing the new high bandwidth lanes; and sending, by the first device, a transition sequence over both the at least one f2s active high bandwidth lane and the new high bandwidth lanes.
