DESCRIPTION
This is the Signal to Noise Ratio (SNR) margin. SNR represents the ratio
of the signal received to the system's noise threshold. The higher the
SNR number, the better the line quality.
This is the difference (in dB) between the power received at the near-
end and that transmitted from the far-end.
This is speed of data transfer on your P-660RU-Tx.
