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.
5.5.9 Linerate Command
Syntax:
192.168.1.1 adsl> linerate
where
= 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 noise 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 noise margins, channel attenuation and the maximum attainable rate.
Downstream and upstream noise margins must both be at least 6 dB. The initial downstream and upstream noise
margins are first set during training. The upstream margin is recalculated every 15 seconds during “showtime” at
the ATU-C and the downstream margin updates every 15 seconds during “showtime” by using EOC messaging.
Information obtained prior to training to steady state transition will not be valid or will be old information.
