shdsl psd { asymmetry | symmetry }
undo shdsl psd
ATM (G.SHDSL) interface view
asymmetry: Specifies the asymmetric mode, where different power spectral
densities (PSD) are set for the central office (CO) and the customer premises
equipment (CPE).
symmetry: Specifies the symmetric mode, where the same PSD is set for the CO
and CPE.
n
Power spectral density (PSD) is the amount of power per unit (density) of
frequency (spectral) as a function of the frequency. PSD describes how the power
of a time series is distributed with frequency.
Use the
shdsl psd
It is not necessarily the same as the one set at CO.
Use the undo shdsl psd
By default, the PSD of the G.SHDSL interface is in symmetric mode.
# Set the PSD of G.SHDSL interface ATM 5/0 to asymmetric mode.

auto: Auto-negotiation mode
rate: Maximum single-pair rate of the G.SHDSL interface, in the range of 64 to
2,312, in units of kbps.
