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).

The table

GATM8 RJ-21 connector wiring on page 222 lists the wiring details for the RJ-21
