● Selectors 1 and 2: Frequency band range
These selectors set the frequency band for the 1st dial tone and the busy tone (before dial-
ing) to be detected.
This setting is effective only when selectors 1 through 3 of WSW05 are set to "1, 1, 1."
● Selector 3: Line current detection
This selector determines whether or not the equipment should detect a line current before
starting dialing.
● Selectors 4 through 6: 2nd dial tone detection level
These selectors set the detection level of the 2nd dial tone.
● Selector 7: 1st dial tone interrupt detecting time
This selector sets the allowable time length of an interrupt which should not be interpreted as
an interrupt in the 1st dial tone dialing.
