Abstract
A novel and useful apparatus for and method of in-band clock compensation for use in synchronous communication systems. The clock compensation mechanism is implemented in each module and is operative to compensate for the differences between the clocks among the various modules in the system. The mechanism operates in band wherein special clock compensation symbols are periodically inserted into the data stream itself. Additional clock sync symbols are added to the data stream depending on the current level of the FIFO queue on the module or card. The insertion (or non-insertion) of additional symbols functions to compensate for the faster (or slower) clock of the module when compared to that of the reference.
