322 Chapter 49 ADSL Commands
The numbers of milliseconds of interleave delay for downstream and upstream transmissions
are listed. The total output power of the transceiver varies with the length and line quality. The
farther away the subscriber’s ADSL modem or router is or the more interference there is on
the line, the higher the power will be. “DS” refers to the power output of the IES-1248-51
“US” refers to the power output of the subscriber’s ADSL modem or router.
Information obtained prior to training to steady state transition will not be valid or will be old
information.
The
atuc information
fields show data acquired from the ATUC (ADSL Termination
Unit – Central), in this case IES-1248-51, 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 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).
49.2.4 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.
<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>.
