l Selectors 1 through 6:
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 highest 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.
l Selector 7: V. 34 mode
This selector determines whether or not the machine communicates with the remote station
in the V. 34 mode when that station supports the V. 34 mode.
