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).

64.4.4 Lineperf Command Example

An example is shown next.

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.
