After changing the Configured Wire option, ASMi-52 must be reset to implement
the change.
When 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 desired target margin with a worst-case
self next noise model given 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.
To configure the Snext margin:
1. From the SHDSL Port Configuration menu, select Snext margin.
The Snext Margin menu appears (see Figure 4-30).
2. Select the Snext margin by typing the number corresponding to the desired
value.
SHDSL Port Configuration menu appears.
3. Select Save to save the changes.
