Two-line phone system
7
A two-line phone system is nothing more than
two separate phone numbers on the same
wall outlet. The two phone numbers can be
on separate jacks (RJ11) or combined into
one jack (RJ14). Your machine must be
plugged into an RJ11 jack. RJ11 and RJ14
jacks may be equal in size and appearance
and both may contain four wires (black, red,
green, yellow). To test the type of jack,
plug in a two-line phone and see if it can
access both lines. If it can, you must separate
the line for your machine. (See Easy Receive
on page 42.)
Converting telephone wall outlets
7
There are three ways to convert to an RJ11
jack. The first two ways may require
assistance from the telephone company. You
can change the wall outlets from one RJ14
jack to two RJ11 jacks. Or, you can have an
RJ11 wall outlet installed and slave or jump
one of the phone numbers to it.
The third way is the easiest: Buy a triplex
adapter. You can plug a triplex adapter into
an RJ14 outlet. It separates the wires into two
separate RJ11 jacks (Line 1, Line 2) and a
third RJ14 jack (Lines 1 and 2). If your
machine is on Line 1, plug the machine into
L1 of the triplex adapter. If your machine is on
Line 2, plug it into L2 of the triple adapter.
Installing machine, external two-line
TAD and two-line telephone
7
When you are installing an external two-line
telephone answering device (TAD) and a
two-line telephone, your machine must be
isolated on one line at both the wall jack and
at the TAD. The most common connection is
to put the machine on Line 2, which is
explained in the following steps. The back of
the two-line TAD must have two telephone
jacks: one labeled L1 or L1/L2, and the other
labeled L2. You will need at least three
telephone line cords, the one that came with
your machine and two for your external two-
line TAD. You will need a fourth line cord if
you add a two-line telephone.
Place the two-line TAD and the two-line
telephone next to your machine.
Plug one end of the telephone line cord for
your machine into the L2 jack of the triplex
adapter. Plug the other end into the LINE jack
on the back of the machine.
Plug one end of the first telephone line cord
for your TAD into the L1 jack of the triplex
adapter. Plug the other end into the L1 or
L1/L2 jack of the two-line TAD.
Plug one end of the second telephone line
cord for your TAD into the L2 jack of the two-
line TAD. Plug the other end into the EXT.
jack on the left side of the machine.
