Dial Line Configuration Options

V32bis Train: Long

Nxt Long Short

V.32bis Train. Controls V.32bis and V.32 train. Determines whether minimum or maximum time durations are used during the V.32bis/V.32 handshaking sequence for both dial and 4-wire/2-wire leased line applications.

NOTE: This configuration option only appears when the Dial Line Rate configuration option is set for Auto:148-3 or any fixed V.32bis data rate.

Long ± Selects long train. Use this setting whenever far-end frequency offset (phase roll) may be encountered. This is usually only required when transmitting over satellite links.

Short ± Allows the modem to train-up faster when using V.32bis/V.32 modulation.

The factory default is Long.

AT command is S-register S43 = n, where n is 0 for Long and 1 for Short.

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 option is not available for modems without a shared or integral DCP.
