column r/w Xdsl2LineTxRefVnDs
This configuration parameter defines the downstream transmitter referred virtual noise.
The TXREFVNds shall be specified through a set of breakpoints.
Each breakpoint shall consist of a subcarrier index t, with a subcarrier spacing of 4.3125 kHz,
and a noise PSD level (expressed in dBm/Hz) at that subcarrier.
The set of breakpoints can then be represented as: [(t1,PSD1), (t2, PSD2), ... , (tN, PSDN)].
32 groups can be configured at most, and 3 bytes for each group. The first two bytes represent tone index,
the 3th byte represents the configured PSD value. The relation between configured PSD value and real PSD 
value is: REAL PSD = (CONFIGURED PSD + 80) * (-0.5dBm/Hz).
