Two-Line Phone System
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 FAX/MFC 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 FAX/MFC.
Converting Telephone Wall Outlets
There are three ways to convert to an RJ11 receptacle. 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). Plug the fax machine into Line 2
of the triplex adapter.
Installing Fax Machine, External Two-Line TAD, and Two-Line
Telephone
When you are installing an external two-line telephone answering device
(TAD) and a two-line telephone, your FAX/MFC must be isolated on one line
at both the wall jack and at the TAD. The most common connection is to put the
FAX/MFC on Line 2. 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 FAX/MFC and two for
your external two-line TAD. You will need a fourth line cord if you add a two-
line telephone.
