NOTE: WSW39 takes effect only in V. 34 mode. For the transmission speed setting in other modes,
refer to WSW19.
Selectors 1 through 8:
These selectors are used to set the modem speed range. With the first transmission speed choice
specified by selectors 1 through 4, 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 5 through 8.
If the modem always falls back to a low transmission speed (e.g., 24,000 bps), set the first
transmission speed choice to the lower one (e.g., modify it from 31,200 bps to 26,400 bps) in order
to deactivate the high-speed modem function and reduce the training time for shorter transmission
time.
WSW39 will be limited by selectors 3 through 8 of WSW40.
