The DPBO PSD Mask profile allows configuration of the ITU-T G.997.1, paragraph 7.3.1.2.13 Downstream Power Back-Off DPBO maximum PSD mask downstream breakpoints (referred to as DPBOPSDMASKds in the ITU-T document). There are a maximum of 16 breakpoints. If a limiting PSD mask profile is not created or configured for a default DPBO data set, for ADSL the assumed default is the set of EPSD breakpoints and for VDSL the default VDSL limiting mask is assumed. Often this set is not configured for VDSL lines.
