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 the next available line.
The calls are usually passed down or “rolled over” to the next
available phone line in a preset order.
Your MFC can work in a roll over system as long as it is connected
to the last number in the sequence, so the call cannot roll away. Do
not put the MFC 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 MFC
will work best on a dedicated line.
Two-Line Phone System
A two-line phone system has two separate phone lines on the same
wall outlet. The two phone lines can be on separate jacks (RJ11)
or combined into one jack (RJ14). If you plug your FAX/MFC
directly into an RJ14 jack, the FAX/MFC will not work. Your 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 fax line for your MFC by converting the wall outlet.
Converting Telephone Wall Outlets
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 MFC is on Line 1, plug the MFC into L1 of the
triplex adapter. If your MFC is on Line 2, plug it into L2 of the
triplex adapter.
