column r/w HUAWEI-VDSL2-LINE-TC-MIBVdsl2VirtualNoiseDs

This configuration parameter defines the downstream 
transmitter referred virtual noise (TXREFVNds). 
The TXREFVNds shall be specified through a set of breakpoints. 
Each breakpoint shall consist of a subcarrier index, 
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)]. 
The subcarrier index shall be coded as an unsigned integer. 
The noise level shall be coded as an 8-bit unsigned integer 
representing the noise level -40 dBm/Hz (coded as 0) to -140 dBm/Hz 
(coded as 200), in steps of 0.5 dBm/Hz. 
Values from 201 to 255 are special values indicating a noise 
level of 0 W/Hz. The maximum number of breakpoints is 32.
