Chapter 52 ADSL Commands
The
atuc information
– Central), in this case IES-612-51A, during negotiation/provisioning message interchanges.
The
atur information
– Remote), in this case the subscriber's DSL modem or router, during negotiation/provisioning
message interchanges. This information can help in identifying the subscriber's DSL 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.
