DESCRIPTION
Enter a descriptive name for identification purposes.
Payload refers to the data embedded in the Ethernet frame, excluding frame
headers and Frame Check Sequence (FCS). Specify the maximum and minimum
downstream payload rates in mega bits per second (Mbps).
Payload refers to the data embedded in the Ethernet frame, excluding frame
headers and Frame Check Sequence (FCS). Specify the maximum and minimum
upstream payload rates in mega bits per second (Mbps).
Select Fixed Mode or Rate Adaptive Decrease Mode.
Select the target upstream SNR (Signal to Noise Ratio) margin.
Select the target downstream SNR (Signal to Noise Ratio) margin.
Select the minimum SNR (Signal to Noise Ratio) margin.
To avoid performance degradation due to RFI (Radio Frequency Interference), set
the switch not to transmit VDSL signals in the RFI band. Select an RFI band
depending on your geographical area.
Select Annex F in Japan.
Select ETSI for European countries.
Select T1E1 in the USA and Asian countries (except Japan).
Select Disable to transmit in the RFI band. Selecting this option may degrade your
VDSL service.
Select the downstream and upstream interleave delay. It is recommended that you
configure the same latency delay for both downstream and upstream.
