zxAnXdsl2LConfProfTxRefVNUs

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 sub-carrier 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.
