Commands with EEC
5-6 ADSL Commands
Figure 5-3 Lineperf Command Example
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), which
is the line card. Downstream (ds) refers to data going from the line card (ATU-C) to the subscriber’s ADSL
modem or router (the ADSL Termination Unit –Remote or ATU-R). Upstream (us) refers to data coming to the
line card from the subscriber’s device.
5.7.9 Linerate Command
Syntax:
192.168.1.1 adsl> linerate <port number>
where
<port number>
=
A port number, from 1 to 24.
The
linerate
command shows the line rate parameters of an ADSL port.
An example is shown next.
Figure 5-4 Linerate Command Example
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.
