xdsl2LConfProfUpboPsdB to 0 is a special configuration to disable UPBO in
the respective upstream band.
This configuration parameter defines the 'b' reference parameter of the UPBO
reference PSD used to compute the upstream power back-off for the upstream
band. A UPBO PSD defined for each band shall consist of two parameters [a,
b]. Parameter 'a' (xdsl2LConfProfUpboPsdA) ranges from 40 dBm/Hz (coded
as 4000) to 80.95 dBm/Hz (coded as 8095) in steps of 0.01 dBm/Hz; and
parameter 'b' (xdsl2LConfProfUpboPsdB) ranges from 0 dBm/Hz (coded as 0)
to 40.95 dBm/Hz (coded as 4095) in steps of 0.01 dBm/Hz. The UPBO
reference PSD at the frequency 'f' expressed in MHz shall be equal to '-a-b
(SQRT(f))'. Setting xdsl2LConfProfUpboPsdA to 4000 and
xdsl2LConfProfUpboPsdB to 0 is a special configuration to disable UPBO in
the respective upstream band.
