configure permanent virtual circuits.
9.1 ADSL Standards Overview
These are the ADSL standards and rates that the ADSL line card supports at the time of writing. The
actual transfer rates will vary depending on what the subscriber’s device supports, the line
conditions and the connection distance.
9.2 VDSL Parameters
The following sections introduce some VDSL parameters.
9.2.1 PSD
PSD (Power Spectral Density) defines the distribution of a VDSL line’s power in the frequency
domain. A PSD mask is a template that specifies the maximum allowable PSD for a line.
9.2.2 Limit PSD Mask
To reduce the impact of interference and attenuation, ITU-T 993.2 specifies a PSD mask to limit the
VDSL2 transmitters PSD at both downstream and upstream.
