xdsl2LConfProfUpboPsdB

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.
