<portlist>
This command shows the line performance counters of an ADSL port.
An example is shown next.

ncrc-I/ncrc-ni

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 (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.
LABEL
nfebe The Number of Far End Block Errors.
ncrc Near end Cyclic Redundancy Checks.
nfec The Near End Corrected blocks.
The Number of Blocks transmitted.
nblks
init The number of link ups and link downs.
n-es The Number of Errored Seconds. This is how many seconds contained at least one errored block or
at least one defect.
n-ses The Number of Severely Errored Seconds. This is how many seconds contained 30% or more
errored blocks or at least one defect. This is a subset of n-es.
n-uas The Number of Unavailable Seconds.
n-lpr The Number of times a Loss of PoweR (on the ATUR) has occurred.
