The query result shows that line template 10 is bound to port 4. Run the
display vdsl line-

command to query the channel profile and line profile in the line template.

Step 2
Confirm whether to change the transmission mode and signal noise ratio (SNR).
The query result shows that line profile 1 and channel profile 10 are in line template 10. Run the
display vdsl line-profile
command to query the transmission mode and SNR configured in the
line profile.

If the transmission mode is ADSL, change the transmission mode to VDSL or ALL. To do
so, proceed to
.
l
If the SNR value does not meet actual requirements over the live network, change it according
to actual conditions. To do so, proceed to
l
If the transmission mode is VDSL or ALL and the SNR value also meets actual conditions
over the live network, go to
.
Step 3
Run the
vdsl line-profile quickadd
command to reconfigure the transmission mode and SNR.
In addition, configure exclusive VDSL parameters.

According to actual conditions over the live network, SNR is planned to 7 dB, transmission
mode to all (its value is 1), and line profile index to 11.
