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).
