LABEL DESCRIPTION
Name Enter a descriptive name for identification purposes.
DownStream The parameters in this column relate to downstream transmissions.
Upstream The parameters in this column relate to upstream transmissions.
Data Rate Type maximum and minimum upstream/downstream transmission rates in kbps for this
profile.
Interleave 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.
Impulse Noise
Protection
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.
Impulse Noise
Protection 8
Specify the level of impulse noise (burst) protection for a slow (or interleaved) channel
when the link is using VDSL profile 30a. 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.
