6.8.7 RFI (Radio Frequency Interference)
RFI is induced noise on the lines by surrounding radio frequency electromagnetic radiation
from sources such as AM and HAM radio stations. Since the VDSL uses a much larger
frequency range that overlaps with other radio frequency systems, signals from VDSL lines
and other radio systems interfere with each other. To avoid performance degradation due to
RFI, set the switch to not transmit VDSL signals in the RFI band.
6.8.8 VDSL Profiles
A profile is a table that contains a list of pre-configured VDSL line settings or VDSL alarm
threshold settings. Each VDSL port has one (and only one) line and alarm profile assigned to it
at any given time.
Profiles allow you to configure VDSL ports efficiently. You can configure all of the VDSL
ports with the same profile, thus removing the need to configure the VDSL ports one-by-one.
You can also change an individual VDSL 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 VDSL port and it takes
care of a large part of the port's configuration.
6.9 VDSL Profile Setup
The line profile defines VDSL parameters such as the payload rates, the upstream/downstream
signal noise margins and impulse noise protection. You can configure multiple profiles,
including profiles for troubleshooting.
To configure or view VDSL profiles, click Basic Setting and VDSL Profile Setup to display
the screen as shown next.
