Low Frequency Wide Band Selected (Figure 7b) (Note 1)
Low Frequency Narrow Band Selected (Figure 7c)
Carrier Level DetectorDelay Enabled*
Carrier Level DetectorDelay Disabled.
Note 1 :
In active tone detection mode (MOD/DTMF = , MC/BC = 1, RTS = 1 see op. modes),
The low frequencywide band is automaticallyselected for the receive channel, whatever the RPRX register programming value.
After a switch back to modem mode (MOD/DTMF = 1,MC/BC = or 1) the RPRX register indicates again the value programmed
before the active tone detection mode.
