Chapter 55 ADSL Commands 383
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).
55.2.4 Lineperf Command
Syntax:
ras> statistics adsl lineperf <portlist>
where
This command shows the line performance counters of an ADSL 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 ADSL port <1>, all ADSL ports <*>
or a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
