l l Selectors 1 through 3: 1st dial tone detection
These selectors activate or deactivate the 1st dial tone detection function which detects the 1st dial
tone issued from the PSTN when a line is connected to the PSTN.
Setting all of these selectors to "1" activates the dial tone detection function so that the equipment
starts dialing upon detection of a dial tone when a line is connected. (However, in those countries
which support no dial tone detection function, e.g., in the U.S.A., setting these selectors to "1"
makes the equipment start dialing after a WAIT of 3.5 seconds.) For the detecting conditions of the
1st dial tone, refer to WSW07 and WSW08.
Other setting combinations deactivate the dial tone detection function so that the equipment starts
dialing after the specified WAIT (3.5, 7.0, 10.5, 14.0, 17.5, 21.0, or 24.5 seconds) without detection
of a dial tone when a line is connected to the PSTN.
