The DPBO Low Freq Override profile allows configuration of the ITU-T G.997.1, paragraph 7.3.1.2.13 Downstream Power Back-Off DPBO low frequency override breakpoints (referred to as DPBOLFO in the ITU-T document). There are a maximum of 16 breakpoints. This set of breakpoints defines the PSD mask that overrides DPBO at low frequencies. If LFO profile is not created or configured for a default DPBO data set no default is needed or provided.
