These counters display line performance data that has been accumulated since the system
started. In the list above the definitions of near end/far end will always be relative to the ATU-
C (ADSL Termination Unit-Central Office). 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.
