These selectors set the frequency band for busy tone to be detected.
• Selectors 3 through 8: ON/OFF time length ranges for busy tone
These selectors set the ON and OFF time length ranges for busy tone to be detected. If more than one
selector is set to "1," the ranges become wider. For example, if selectors 4 and 5 are set to "1," the
ON and OFF time length ranges are from 175 to 600 ms.
