NOTE: Selectors 1, 2, 4 through 7 are not applicable in those countries where no dial tone or line current detection is supported, e.g., U.S.A.
•Selectors 1 and 2: Frequency band range
These selectors set the frequency band for the 1st dial tone and the busy tone (before dialing) 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.
