Modifying the Power Spectral Density (PSD) DSL Port Template Parameters
Modifies the Power Spectral Density (PSD) parameters for a DSL Port template that can be
applied to a DSL port, replacing the DSL port settings.
PSD settings only apply to VDSL2 and VDSL2MM Service Types, and are only used when a
line trains up in VDSL2 mode.
Parameters for the PSD parameters of an xDSL port
Parameter Description Valid Options
Limit mask A PSD limit mask describes how the xDSL port and modem (CPE)
will cap power across the range of transmit frequencies. By
changing the PSD limit mask, a particular transmission scheme can
be shaped so as to coexist with different underlying technologies
(e.g. POTS or ISDN) on the same wire pair. In addition, you can
select a VDSL QAM PSD mask. Developed by Calix in cooperation
with Broadcom, this limit mask is compatible with QAM-based
VDSL, which was widely deployed by older NextLevel
Communications (NLC) systems and known as Classic VDSL. With
this limit mask, both VDSL2 and VDSL1 QAM technologies can
coexist in the same copper loop binder group.
