6.11 VDSL PSD Profile Setup
PSD (Power Spectral Density) profiles define the allowable downstream and upstream PSD values for a line. In a PSD profile, you can configure a set of breakpoints, each of which is defined by a frequency and PSD level. The set of breakpoints forms a PSD mask that specifies the maximum transmission power of each VDSL frequency band. If the frequency range used by the Switch and other devices overlap, you can configure the PSD of your Switch to prevent interference with other nearby signals.
In the following example, the Switch’s PSD is configured to not exceed the PSD mask (dashed line) within the 5 MHz to 16 MHz frequency range. After configuration, the shaded area is the Switch’s actual PSD for the specified frequency range.
