column r/w HUAWEI-VDSL2-LINE-TC-MIBVdsl2VirtualNoiseUs
This configuration parameter defines the upstream 
transmitter referred virtual noise (TXREFVNus). 
The TXREFVNus 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)]. 
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 16.
