11.6 Configured Versus Actual SHDSL Rates

You configure the maximum and minimum rates of individual SHDSL ports using the set
profile command. However, due to noise and other factors on the line, the actual rate may not
reach the maximum that you specify.
Chapter 11 Profile Screens
DESCRIPTION
The following parameters relate to downstream transmissions.
Type a maximum downstream transfer rate for this port. Configure the maximum
downstream transfer rate to be greater than the maximum upstream transfer rate.
Type the minimum downstream transfer rate for this port. Configure the minimum
downstream transfer rate to be less than the maximum downstream transfer rate.
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.
Type the maximum downstream signal to noise margin (measured in tenths of a
decibel).
Type the minimum downstream signal to noise margin (measured in tenths of a
decibel). Configure the minimum downstream signal to noise margin to be less
than or equal to the maximum downstream signal to noise margin.
Type the target downstream signal to noise margin (measured in tenths of a
decibel). Configure the target downstream signal to noise margin to be greater
than or equal to the minimum downstream signal to noise margin and less than or
equal to the maximum downstream signal to noise margin.
Click Apply to save the changes in this screen to the system's volatile memory.
The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your
changes to the non-volatile memory when you are done configuring.
While you are modifying a profile, you can click New to start configuring a fresh
profile without saving your changes.
Click Cancel to start configuring the screen again.
This is the port profile index number.
These are the names of individual profiles. The DEFVAL profile always exists and
all of the DSL ports have it assigned to them by default.
This is the ADSL latency mode (fast or interleave) for the ports that belong to this
profile.
These are the downstream and upstream rate adaptation settings for the ports that
belong to this profile.
These are the maximum downstream and upstream transfer rates for the ports that
belong to this profile.
Select a profile's Select radio button and click Modify to edit the profile.
Select a profile's Select radio button and click Delete to remove the profile.
