Note)
Note: The AUX port supports full data speeds. When the line is in use by an analog device, the icon is lit on the
phone to indicate it is in use. If you try to seize the line using the phone, the display shows "in use". Also, if a
power failure occurs, an analog set on line 1 activates (powered by the CO).
