Dial Line Configuration Options

Asymmetric Rate: Enable

Nxt Enable Disable

Asymmetric Rate. Controls rate symmetry when running V.34 modulation. (This configuration option does not appear unless V.34 modulation is selected.)

Enable ± The modem operates in asymmetric rate mode (the transmit and receive rates can be different) when running V.34 modulation. Asymmetric Rate must be enabled in both modems.

Disable ± The modem operates in symmetric rate mode (the transmit and receive rates are identical) when running V.34 modulation. Either modem can force symmetric mode by disabling Asymmetric Rate.

The factory default is Enable.

AT command equivalent is S-register S14=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.
