Interleave
Delay (ms)
Configure this field when you set the Latency Mode field to Interleave. Type the
number of milliseconds of interleave delay to use for upstream transfers. It is
recommended that you configure the same latency delay for both upstream and
downstream.
Max SNR (0.1
dB)
Type the maximum upstream signal to noise margin (measured in tenths of a decibel).
Min SNR (0.1
dB)
Type the minimum upstream signal to noise margin (measured in tenths of a decibel).
Configure the minimum upstream signal to noise margin to be less than or equal to the
maximum upstream signal to noise margin.
Target SNR
(0.1 dB)
Type the target upstream signal to noise margin (measured in tenths of a decibel).
Configure the target upstream signal to noise margin to be greater than or equal to the
minimum upstream signal to noise margin and less than or equal to the maximum
upstream signal to noise margin.
RA Mode Select how the device adjusts the upstream rate from the configured transmission rate to
the attainable transmission rate depending on the line quality.
Select fix to use a fixed rate you specified in the upstream Max Rate field.
Select startup to use the rate negotiated at link initialization.
Select runtime to use rate adaptation at any time while the connection is up.
Up-shift Noise
Margin
The upstream up shift signal to noise margin (measured in tenths of a decibel). When the
channel’s signal to noise margin goes above this number, the device can attempt to use a
higher transfer rate. Configure the upstream up shift signal to noise margin to be greater
than or equal to the target upstream signal to noise margin and less than or equal to the
maximum upstream signal to noise margin.
Down-shift
Noise Margin
The upstream down shift signal to noise margin (measured in tenths of a decibel). When
the channel’s signal to noise margin goes below this number, the device shifts to a lower
transfer rate. Configure the upstream down shift signal to noise margin to be less than or
equal to the target upstream signal to noise margin and greater than or equal to the
minimum upstream signal to noise margin.
Downstream The following parameters relate to downstream transmissions.
Max Rate
(kbps)
Type a maximum downstream transfer rate for this port. Configure the maximum
downstream transfer rate to be greater than the maximum upstream transfer rate.
Min Rate
(Kbps)
Type the minimum downstream transfer rate for this port. Configure the minimum
downstream transfer rate to be less than the maximum downstream transfer rate.
Interleave
Delay (ms)
Configure this field when you set the Latency Mode field to interleave. Type the number of
milliseconds of interleave delay to use for upstream transfers. It is recommended that you
configure the same latency delay for both upstream and downstream.
Max SNR (0.1
dB)
Type the maximum downstream signal to noise margin (measured in tenths of a decibel).
Min SNR (0.1
dB)
Type the minimum downstream signal to noise margin (measured in tenths of a decibel).
Configure the minimum downstream signal to noise margin to be less than or equal to the
maximum downstream signal to noise margin.
Target SNR
(0.1 dB)
Type the target downstream signal to noise margin (measured in tenths of a decibel).
Configure the target downstream signal to noise margin to be greater than or equal to the
minimum downstream signal to noise margin and less than or equal to the maximum
downstream signal to noise margin.
RA Mode Select how the device adjusts the downstream rate from the configured transmission rate
to the attainable transmission rate depending on the line quality.
Select fix to use a fixed rate you specified in the downstream Max Rate field.
Select startup to use the rate negotiated at link initialization.
Select runtime to use rate adaptation at any time while the connection is up.
