4-18 Configuring for Operation ASMi-52 Ver. 2.8
 Enabled – Adaptive mode. The transmission power is between 13.5 to
14.5 dBm and the transmitter will use this range for the optimal
transmission according to the line conditions and bitrates. This setting
enables the modems to transmit at their minimum power, which should
improve the Signal to Noise Relation (SNR) and avoid errors with data
reception.
The display is refreshed and a new value appears.

• After changing the Configured Wire option, ASMi-52 must be reset to
implement the change.
• When ASMi-52 is operating in Line prob. Adaptive rate, and the clock is
internal, the rate is limited up to 2048 bps.
Configuring the Snext Margin
The Snext margin indicates the minimum required target margin with a worst-
case self next noise model given the current loop insertion (49 SHDSL next is
considered the worst case). This setting is available only if the rate adaptation is
enabled (see the line probing configuration below).
•
Disabling the Snext margin parameter allows the use of all line rates, regardless
of line condition.
³ To configure the Snext margin:
1. From the SHDSL Remote Port menu, select Snext margin (Main menu >
Configuration > SHDSL Configuration > SHDSL Remote Port > Snext Margin).
The Snext Margin menu appears (see
Figure 4-23 ).
2. Select the Snext margin by typing the number corresponding to the required
value.
The SHDSL Remote Port menu appears.
3. Select Save to save the changes.
