5.3.2.12 Bitloading Per Tone
The bitloading per tone command is used to fetch the table that shows bit loading, SNR,
attenuation, FEQ fine coeff, noise margin, and so on.
To display the table of each parameter in the range of tone, use the following command.
Command Mode Description
show lre pertoneinfo PORT {rx-bit-neㅣtx-bit-ne
| snr-ne | noise-margin-ne | atten-ne | feq-ne |
tx-pwr-ne | tx-gi-ne | qln-ne | coarse-feq-ne }
