NOTE: Selector 7 takes effect only in models supporting V.34 mode.
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 machine
attempts to establish the transmission link via the MODEM. If the establishment
fails, the machine automatically steps down to the next lowest speed and attempts
to establish the transmission link again. The machine 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 high-speed MODEM function
and reduce the training time for shorter transmission time.
Generally, to save the transmission time, set the last transmission speed choice to
a higher one.
