* In those models with a maximum of 9600 bps capability, selection of 12,000 bps or 14,400 bps will still
only produce a set speed automatically reduced to 9600 bps.
NOTE: Selector 8 is applicable only to those models that support 14,400 bps.
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 equipment attempts to establish the transmission link via the
MODEM. If the establishment fails, the equipment automatically steps down to the next lowest
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 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.
