These counters display line performance data that has been accumulated since the system
started. The definitions of near end/far end are relative to the ATU-C (ADSL Termination
Unit-Central Office). Downstream refers to data from the ATU-C and upstream refers to data
from the ATU-R. "interleave" stands for interleaved and "fast" 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.
