Syntax:
ras> statistics adsl lineperf <portlist>

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.

DESCRIPTION
The Number of Far End Block Errors (Cyclic Redundancy Check).
Near end Cyclic Redundancy Check errors.
The Near End blocks repaired by Forward Error Correction.
The number of Blocks transmitted (downstream) or received (upstream) on this
ADSL port. 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.
The number of link ups and link downs.
The Number of Errored Seconds. This is how many seconds contained at least
one errored block or at least one defect.
The Number of Severely Errored Seconds. This is how many seconds
contained 30% or more errored blocks. This is a subset of n-es.
The Number of Unavailable Seconds.
The Number of times a Loss of Power (on the ATUR) has occurred.
