Configuring the Current Margin
The current margin indicates the minimum required target margin for the local
line conditions during the startup sequence. This setting is available only if the
rate adaptation is enabled (see the line probing configuration below).
•
Disabling the current margin parameter allows the use of all line rates, regardless
of the line condition.
³ To configure the current margin:
1. From the SHDSL Remote Port menu, select Current Margin (Main menu >
Configuration > SHDSL Configuration > SHDSL Remote Port > Current Margin).
The Current Margin menu appears. The display is identical to the Snext
Margin menu, except for its title (see
Figure
4-23
).
2. Select the current margin by typing the number corresponding to the required
value, and press <Enter>.
The SHDSL Remote Port menu appears.
3. Select Save to save the changes.
Configuring the Power Spectral Density
By configuring the power spectral density, you define the amount of power
applied to the spectrum of frequencies that carry the information signal in order
to achieve a satisfactory level of signal strength at the receiving end of the
circuit.
The power spectral density can be configured for the ASMi-52 units with the line
probing set to fixed.
The power spectral density value depends on the selected modems’ compatibility:
Annex A or Annex B. The possible values are:
