Step 2 – CO Line Connections
The X16 system supports a single CO Line per port, or two CO lines in
ports labeled 1/2 and 3/4.
Note: The port labeled “Line 1” is a direct access auxiliary port for line 1 allowing an
analog device direct access.
Telephone lines are usually found on the center pair (White/Blue) of the
telephone jack (RJ11). Sometimes a second line will be connected to the
outer pair (White/Orange). The system is design to accommodate both types
of installations. When using only the center pair, connect 1 telephone line to
each of the 4 ports in the system. When using both the center and outer
pairs, use only ports labeled 1/2 and 3/4 to connect all 4 lines. The existing
cabling will determine how the telephone lines will be connected to the
system.
Note: The port labeled “Line 1” gives you access to the telephone company line
(white/blue) plugged into the Central Office Port labeled 1/2. This is useful during a Power
Failure or anytime you want to access to line 1 from an Analog telephone.
