DESCRIPTION
Enter a descriptive name for identification purposes.
The parameters in this column relate to downstream transmissions.
The parameters in this column relate to upstream transmissions.
Type maximum and minimum upstream/downstream transmission rates in kbps for
this profile.
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.
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.
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.
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 system enable this feature when there is no impact to the
data rate.
