DESCRIPTION
When editing a profile, this is the name of this profile. When adding a profile, type a name
(up to 31 characters) for the profile.
This field sets the VDSL latency mode for the ports that belong to this profile.
Select fast mode to use no interleaving and have faster transmission (a "fast channel").
This would be suitable if you have a good line where little error correction is necessary.
Select interleave mode to use interleave delay when transmission error correction
(Reed- Solomon) is necessary due to a less than ideal telephone line.
See Section 11.2 on page 331
The following parameters relate to upstream transmissions.
Type a maximum upstream transfer rate for this profile. Configure the maximum
upstream transfer rate to be less than the maximum downstream transfer rate.
Type the minimum upstream transfer rate for this port. Configure the minimum upstream
transfer rate to be less than the maximum upstream transfer rate.
