Net Data Rate Type maximum and minimum upstream/downstream transmission rates in kbps for this
profile.
MaxInterleave
Delay
Type the number of milliseconds of interleave delays used for downstream and upstream
transmissions. It is recommended that you configure the same latency delays for both
upstream and downstream.
Min INP Specify the level of impulse noise (burst) protection for a slow (or interleaved) channel.
Select a number between 0 and 16.
This parameter is defined as the number of consecutive DMT symbols or fractions thereof.
The number of symbols decides how long in one period errors can be completely
corrected. A higher symbol value provides higher error correction capability, but it causes
overhead and higher delay which may impact multimedia data receiving quality.
Min INP8 Specify the level of impulse noise (burst) protection for a slow (or interleaved) channel for
VDSL2 profile 30a. Enter a number between 0 and 16.
The DMT symbols with a sub-carrier spacing for DS/US min INP8 is 8.625 kHz (DS/US min
INP is 4.3125 kHz).
PhyR Select Enable to use the VDSL physical layer for data re-transmission when impulse noise
occurs. This helps to get better link connection quality.
Select Disable to turn this feature off.
Select Auto to have the Switch enable this feature when there is no impact to the data
rate.
SOS Min Data
Rate
Specify the minimum upstream/downstream data rates (guaranteed data rates) if you set
the Switch to use SOS for immediate rate adjustment. The Switch drops the line if the
upstream or downstream data rate goes down below the set data rate.
GINP This field displays the upstream/downstream G.INP mode. Click Modify to change the
G.INP settings.
Add Click Add to save the new settings to the Switch. It then displays in the summary table at
the bottom of the screen.
Cancel Click Cancel to reset the fields to your previous configuration.
Clear Click Clear to clear the fields to the factory defaults.
Name This field displays the descriptive name of a profile.
Payload Rate This field displays the configured maximum upstream and downstream data transmission
rates in megabits per second in a profile.
Min INP This field displays the configured minimum upstream and downstream impulse noise
protection levels in a profile.
Max Delay This field displays the configured maximum upstream and downstream interleave delays
in a profile.
Applied Ports This field displays the VDSL port number(s) to which this profile is applied.
Delete Check the rule(s) that you want to remove in the Delete column and then click the
Delete button.
Cancel Click Cancel to clear the selected checkboxes in the Delete column.
