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 (RJll) or
combined into one jack (RJl4). Your fax machine must be plugged into an RJl 1
jack. RJll and RJl4 jacks may be equal in size and appearance and both may
contain 4 wires (biack, 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 machine.
Converting Telephone Wall Outlets
There are three ways to convert to an RJl 1 receptacle. The first two ways may
require assistance from the telephone company. You can change the wall outlets
from one RJl4 jack to two RJll jacks. Or, you can have an RJll 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 RJl 1 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, TWo-Line TAD,
and Two-Line Telephone
when you are installing a two-line teiephone answering device (TAD) and a two-
line telephone, your fax machine must be isolated on one line at both the wall
jack and at the TAD. The most common connection is to put the fax machine on
Line 2, The back of the two-iine TAD must have two telephone jacks: one labeled
LI or L1/L2, and the other labeled L2. You will need at least three telephone line
cords, the one that came with your fax machine and two for your two-line TAD.
You will need a fourth line cord if you add a two-line telephone.
