LABEL DESCRIPTION
Up Click this link to go to the card's Profile Setup screen.
Profile Name When editing a profile, this is the name of this profile. When adding a profile, type a name
for the profile.
Latency Mode This field sets the ADSL 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 3.5 for more on interleave delay.
Upstream The following parameters relate to upstream transmissions.
Max Rate (Kbps) Type a maximum upstream transfer rate (32 to 3000 Kbps) for this profile. Configure the
maximum upstream transfer rate to be less than the maximum downstream transfer rate.
Min Rate (Kbps) Type the minimum upstream transfer rate (32 to 3000 Kbps) for this port. Configure the
minimum upstream transfer rate to be less than the maximum upstream transfer rate.
Latency Delay(ms) 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.
