Chapter 64 ADSL Commands
The atur information fields show data acquired from the ATUR (ADSL
Termination Unit – Remote), in this case the subscriber's ADSL modem or router,
during negotiation/provisioning message interchanges. This information can help
in identifying the subscriber's ADSL modem or router.
The vendor ID, vendor version number and product serial number are obtained
from vendor ID fields (see ITU-T G.994.1) or R-MSGS1 (see T1.413).

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 Far End blocks repaired by Forward Error Correction.
The Near End blocks repaired by Forward Error Correction.
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.
0 (Far End CRC)
0 (Near End CRC)
0 (Far End Corrected FEC)
