A method and system for multiplexing high priority, low bandwidth information into a link carrying message passing information. The information is multiplexed in a way that keeps the two information streams and their associated hardware largely independent, but allows the most costly system components: the line drivers, receivers, and cables; to be shared by the two functions. The encoding chosen for the high priority information allows its insertion anywhere in the message passing data stream thus minimizing latency and jitter. The encoding is also a subset of the full 8B/10B encode/decode circuit, thus minimizing the extra hardware required.
