ADSL Commands

7-7

non-ses-blks-ds/non-ses-blks-us : 120878/120878

n-uas-ds/n-uas-us : 0/0

fe_loss_seconds/ne_loss_seconds : 0/0

fe_fec_seconds/ne_fec_seconds : 0/0

fast_trains : 0

fast_trains_fail : 0

These counts contain 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.

7.5.9 Linerate

Command

Syntax:

192.168.1.1 adsl> linerate

where

= A port number, from 1 to 8.

The linerate command shows the line rate parameters of an ADSL port.

An example is shown next.

192.168.1.1 adsl> linerate 7

Current Active Rates:

AS0 downstream rate : 2048 Kbps

AS1 downstream rate : 0 Kbps

LS0 upstream rate : 512 Kbps

LS1 upstream rate : 0 Kbps

Down/up stream Margin : 31/22 dB

Down/up stream Attenuation : 0/ 0 dB

Attainable Down/up stream Rate : 11456/ 1344 Kbps

These results contain the current downstream and upstream operating values (SHOWTIME) for the requested line,
the latest available downstream and upstream margins, channel attenuation and the maximum attainable rate.

Downstream and upstream margins must both be at least 6 dB. The initial downstream and upstream margins are
first set during training. The upstream margin is recalculated every 15 seconds during “show time” at the ATU-C
and the downstream margin updates every 15 seconds during “show time” by using EOC messaging.

Information obtained prior to training to steady state transition will not be valid or will be old information.
