headers and Frame Check Sequence (FCS). Specify the maximum and minimum
downstream payload rates in mega bits per second (Mbps).
Upstream Payload
Rate
Payload refers to the data embedded in the Ethernet frame, excluding frame
headers and Frame Check Sequence (FCS). Specify the maximum and minimum

Rate Adaptive Select Fixed Mode or Rate Adaptive Decrease Mode .
Target Upstream
SNR Margin
Select the target upstream SNR (Signal to Noise Ratio) margin.
Target
Downstream SNR
Margin
Select the target downstream SNR (Signal to Noise Ratio) margin.
Min SNR Margin Select the minimum SNR (Signal to Noise Ratio) margin.
