Max SNR Type the maximum upstream signal to noise margin (0-31 dB).

Min SNR Type the minimum upstream signal to noise margin (0-31 dB).

Configure the minimum upstream signal to noise margin to be less

than or equal to the maximum upstream signal to noise margin.

Target SNR Type the target upstream signal to noise margin (0-31 dB). 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.

Up Shift SNR The upstream up shift signal to noise margin (0-31 dB). 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 SNR The upstream down shift signal to noise margin (0-31 dB). 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.

Down Stream The following parameters relate to downstream transmissions.

Max Rate Type a maximum downstream transfer rate (64 to 32000 Kbps) bps

for this port. Configure the maximum downstream transfer rate to be

greater than the maximum upstream transfer rate.

Min Rate Type the minimum downstream transfer rate (32 to 32000 Kbps) for

this port. Configure the minimum downstream transfer rate to be less

than the maximum downstream transfer rate.

Interleave Delay Configure this field when you set the Latency Mode field to

interleave. Type the number of milliseconds (1-255) 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 Type the maximum downstream signal to noise margin (0-31 dB).

Min SNR Type the minimum downstream signal to noise margin (0-31 dB).

Configure the minimum downstream signal to noise margin to be less

than or equal to the maximum downstream signal to noise margin.

Target SNR Type the target downstream signal to noise margin (0-31 dB).

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.

Up Shift SNR The downstream up shift signal to noise margin (0-31 dB). When the

channel’s signal to noise margin goes above this number, the device

can attempt to use a higher transfer rate. Configure the downstream

up shift signal to noise margin to be greater than or equal to the

target downstream signal to noise margin and less than or equal to

the maximum downstream signal to noise margin.
