4x16 wiring chart
The analog telephones lines connect to the 4x16 through the RJ-11 jacks
(labeled 1 to 4) on the front of the MBM. Do not connect analog telephone
lines to the auxiliary jack on the front of the media bay module. These jacks
are intended for analog telephones designated as emergency telephones. To
view the 4x16 connectors, see
Figure 30 4x16 connectors (page 137)

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).
