11.5 VDSL Profile Setup
Click Profile > VDSL in the navigation panel to open the following screen. Use this screen to
configure VDSL profiles for VLCs that follow the VDSL MIB as defined in ADSL Extension Line MIB
(RFC 3440). Later you can use the VDSL profiles to configure VDSL ports in the
VDSL Port Setup
screens.
Down-shift
Noise Margin
(0.1 dB)
The downstream down shift signal to noise margin (measured in tenths of a decibel).
When the channel’s signal to noise margin goes below this number, the device shifts to a
lower transfer rate. Configure the downstream down shift signal to noise margin to be
less than or equal to the target downstream signal to noise margin and greater than or
equal to the minimum downstream signal to noise margin.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The
system loses these changes if it is turned off or loses power, so use the Config Save link
on the navigation panel and then the Save button to save your changes to the non-
volatile memory when you are done configuring.
New While you are modifying a profile, you can click New to start configuring a fresh profile
without saving your changes.
Cancel Click Cancel to start configuring the screen again.
The bottom part of the screen lists the configured profiles.
Index This is the port profile index number.
Name These are the names of individual profiles. The DEFVAL profile always exists and all of the
DSL ports have it assigned to them by default.
Latency Mode This is the ADSL latency mode ( fast or interleave ) for the ports that belong to this
profile.
Down/Up RA
Mode These are the downstream and upstream rate adaptation settings for the ports that
belong to this profile.
Down/Up Max
Rate (kbps) These are the maximum downstream and upstream transfer rates for the ports that
belong to this profile.
Modify Select a profile’s Select radio button and click Modify to edit the profile.
Delete Select a profile’s Select radio button and click Delete to remove the profile.
