IES-612-51A User’s Guide

The atuc information fields show data acquired from the ATUC (ADSL Termination Unit
– Central), in this case IES-612-51A, during negotiation/provisioning message interchanges.
The
atur information fields show data acquired from the ATUR (ADSL Termination Unit
– 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).
52.2.4 Lineperf Command
Syntax:
ras> statistics adsl lineperf <portlist>
where
This command shows the line performance counters of a DSL port.
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.
<portlist> =
You can specify a single DSL port <1>, all DSL ports <*> or
a list of DSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
