Special line considerations 7
Roll over telephone lines 7
A roll over telephone system is a group of two
or more separate telephone lines that pass
incoming calls to each other if they are busy.
The calls are usually passed down or ‘rolled
over’ to the next available telephone line in a
preset order.
Your machine can work in a roll over system
as long as it is the last number in the
sequence, so the call cannot roll away. Do not
put the machine on any of the other numbers;
when the other lines are busy and a second
fax call is received, the fax call will be sent to
a line that does not have a fax machine. Your
machine will work best on a dedicated
line.
Two-line telephone system 7
A two-line telephone system is nothing more
than two separate telephone numbers on the
same wall outlet. The two telephone numbers
can be on separate jacks (RJ11) or mixed 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 telephone and see if it can access
both lines. If it can, you must separate the line
for your machine. (See page 45.)
Converting telephone wall outlets 7
There are three ways to convert to an RJ11
jack. The first two ways may require help 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
telephone 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.
a Put the two-line TAD and the two-line
telephone next to your machine.
b 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.
c 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.
