                        Figure 10-4 – Example of tone ordering and pairing including one-bit subcarriers
            NOTE 1 – In this example, tones 3, 5, 7 and 10 implement the RMC tone set (RTS). The number of tones in RTS is
            NSCR=4. There are a total of 23 tones in the DMT symbol and 37 bits in the symbol
