Special Line Considerations

Roll Over Phone Lines

A roll over phone 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 phone line in a preset order.
Your fax 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 fax machine on any of the other
numbers; when the other lines are busy and a second fax call is received, the fax call
is transferred to a line that does not have a fax machine. Your fax machine will work
best on a dedicated line.

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 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.

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). If your Brother 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 triplex adapter.
