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, in the event of a power failure an analog set on line 1 goes active (powered by the CO).
