Dial Line Configuration Options
Proactive Retrain: Enable
Nxt Enable Disable
Proactive Retrain. When enabled, the dial line connection is monitored, and if the Signal to Noise Ratio drops 1.2 dB or
more, the modem forces a retrain. This may prevent bit errors at higher rates over marginal lines. Disabling Proactive
Retrain reduces the number of retrains while increasing the exposure to bit errors.
NOTE: This configuration option is valid only for dial lines at the V.34 rates 31200 and 33600.
Disable – Proactive Retrain is disabled.
Enable – Proactive Retrain is enabled.
AT command equivalent is S23=
n.
FallFwdDelay: Disable
End Disable 5_mins 15_mins 1_hour
Fall Forward Delay. Provides an initial delay before leased or dial lines are monitored for fall forward conditions. After the
timer expires, monitoring occurs as usual. Possible delay times are 5 minutes, 15 minutes, or 1 hour.
The factory default is Disable (no delay).
NOTE: Fall Forward Delay appears under both the Dial Line configuration options and the Leased Line configuration
options, but the same setting is used for both. Changing it in one place effectively changes it in the other.
There is no analogous AT command, so this configuration option is not available for modems without a shared or integral
DCP.
