Downstream (ds) refers to data from the ATU-C and upstream (us) refers to data from the ATU-R. “I” stands for interleaved and “ni” stands for non-interleaved (fast mode).

A block is a set of consecutive bits associated with the path; each bit belongs to one and only one block. Consecutive bits may not be contiguous in time.
