Command Usage
Use this command without the interface parameter to display the PSD
used for all VDSL ports on the switch, or with an interface to display
it used for a specific port.
The Power Spectral Density (PSD) defines the power spectrum used
over all of the VDSL upstream and downstream channels. It is
configured using the lre psd-breakpoints command (page 29-12), lre
psd-frequencies command (page29-13), and lre psd-value
command (page 29-15).
Example
This example shows that the default PSD is set at -12 dBm/Hz for all of
the breakpoints for Port 1. No slopes at the bounding frequencies nor
peaks at the center frequency for any band has been configured.
