Use this command to activate or deactivate the VDSL driver.
4.1.3 VDSL Uprate and Downrate Commands
Use the following commands to view and set VDSL upstream and downstream rates. Rates vary according to
VDSL mode selected – see
Table 4-4 and section 4.1.1.
Upstream Rates
vdsl uprate [uprate]
“uprate” is an integer from 0 to 4 as defined in the next table. This command sets the upstream VDSL rate if you
set a rate and displays the rate if you don’t. If you set a new rate, you must use “vdsl reset” or “vdsl reconnect”
command to reconnect.
Figure 4-2 VDSL Upstream Rate
Downstream Rates
vdsl downrate [downrate]
“downrate” is an integer from 0 to 4 defined in the next table. This command sets the upstream VDSL rate if you
set a rate and displays the rate if you don’t. If you set the rate, you must use “vdsl reset” or “vdsl reconnect”
command to make VDSL reconnect.
