•Selectors 1 through 6: First and last choices of transmission speed for fallback
These selectors are used to set the modem speed range. With the first transmission speed choice specified by selectors 1 through 3, the equipment attempts to establish the transmission link via the modem. If the establishment fails, the equipment automatically steps down to the next highest speed and attempts to establish the transmission link again. The equipment repeats this sequence while stepping down the transmission speed to the last choice specified by selectors 4 through 6.
If the modem always falls back to a low transmission speed (e.g., 4,800 bps), set the first transmission speed choice to the lower one (e.g., modify it from 12,000 bps to 7,200 bps) in order to deactivate the
Generally, to save the transmission time, set the last transmission speed choice to a higher one.
•Selector 7: V. 34 mode
This selector determines whether or not the equipment communicates with the remote station in the V. 34 mode when that station supports the V. 34 mode.
