<WSW38>
Note:
WSW38 takes effect only when the V.34 mode is permitted (WSW19, selector 7) in models
supporting V.34 mode.
• Selectors 1 and 2: Setting of the equalizer
These selectors set the equalizer's training level to be applied if the machine fails to send
training due to weak line connection. If these selectors are set to "0, X," the modem will
automatically set the appropriate training level.
• Selector 3: Sending level of guard tone at phase 2
This selector sets the sending level of guard tone for 1800 Hz to be sent at Phase 2 in the
V. 34 mode.
• Selector 4: Stepping down the transmission speed at fallback each
This selector determines how much the modem steps down the transmission speed at
fallback when called by the remote station. If this selector is set to "1," the modem may
step down the transmission speed from 33600 bps to 28800 bps by one-time fallback.
• Selectors 5 and 6:
Automatic control of modem's EQM gain for proper transmission speed choice
These selectors determine how the modem controls the EQM (Eye Quality Monitor) gain
for proper choice of the transmission speed, which applies if the modem selects higher
transmission speed than the possible speed so that it always repeats falling back.
• Selector 8: Detection of CED for stopping CNG
If this selector is set to "0," the detection time of CED specified by WSW43, selectors 4 and
5 will apply.
