the port for the ATU-C and ATU-R. The maximum SNR is
always 16 dB, while the minimum is always 0 dB. The SNR
margin for rate downshift is 3 dB below the Target SNR
Margin. When the SNR margin falls below this level, the
device will attempt to decrease its transmit rate. The SNR
margin for rate upshift is 2 dB above the Target SNR
Margin. When the noise margin rises above this level, the
device will attempt to increase its transmit rate. Rate shifts
occur as soon as the margin threshold is exceeded.
