11.6 VDSL2 Profiles

These profiles apply to the VLCs that follow the VDSL2 MIB (defined in draft-ietf-adslmib-vdsl2-06).
11.6.1 VDSL2 Profiles
A profile is a table that contains a list of pre-configured VDSL2 line settings or VDSL2 alarm
threshold settings. Each VDSL2 port has one (and only one) line and alarm profile assigned to it at
any given time.
Profiles allow you to configure VDSL2 ports efficiently. You can configure all of the VDSL2 ports with
the same profile, thus removing the need to configure the VDSL2 ports one-by-one. You can also
change an individual VDSL2 port by assigning it a different profile.
For example, you could set up different profiles for different kinds of accounts (for example,
economy, standard and premium). Assign the appropriate profile to a VDSL2 port and it takes care
of a large part of the port's configuration.

DESCRIPTION
The downstream up shift signal to noise margin (measured in tenths of a decibel). When
the channel's signal to noise margin goes above this number, the device can attempt to
use a higher transfer rate. Configure the downstream up shift signal to noise margin to be
greater than or equal to the target downstream signal to noise margin and less than or
equal to the maximum downstream signal to noise margin.
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.
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.
While you are modifying a profile, you can click New to start configuring a fresh profile
without saving your changes.
Click Cancel to start configuring the screen again.
This is the port profile index number.
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.
This is the VDSL latency mode (fast or interleave) for the ports that belong to this
profile.
These are the downstream and upstream rate adaptation settings for the ports that
belong to this profile.
These are the maximum downstream and upstream transfer rates for the ports that
belong to this profile.
Select a profile's Select radio button and click Modify to edit the profile.
Select a profile's Select radio button and click Delete to remove the profile.
