4.1.2VDSL Active Command
vdsl active [onoff]
Use this command to activate or deactivate the VDSL driver.
4.1.3VDSL 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
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.
P841C>vdsl uprate
vdsl upstream rate: 1562500 bps (0)
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.
