Last transmission speed choice
for fallback
Note:
WSW39 takes effect only when the V.34 mode is permitted (WSW19, selector 7) in models
supporting V.34 mode. For the transmission speed setting in other modes, refer to WSW19.
- Selectors 1 through 8: 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 4, 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 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 on WSW40.
