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 MFC 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 MFC on any of the
other numbers; when the other lines are busy and a second fax call is
received, the fax call would be 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 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 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 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 MFC
into Line 2 of the triplex adapter.
