The following table describes the fields in this screen.
Table 159 ADSL Profile
LABEL DESCRIPTION
The top part of the screen is for profile configuration.
Name 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.
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 12.2 on page 333 for more on interleave delay.
Upstream The following parameters relate to upstream transmissions.
Max Rate
(kbps)
Type a maximum upstream transfer rate 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 for this port. Configure the minimum upstream
transfer rate to be less than the maximum upstream transfer rate.
Interleave
Delay (ms)
Configure this field when you set the Latency Mode field to Interleave. Type the
number of milliseconds of interleave delay to use for upstream transfers. It is
recommended that you configure the same latency delay for both upstream and
downstream.
Max SNR (0.1
dB)
Type the maximum upstream signal to noise margin (measured in tenths of a decibel).
