FOR YOUR INFORMATION
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 can not 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 MFC.
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
(RJ 1l) or combined into one jack (RJ 14). Your MFC must be plugged into an
RJ 11 jack. RJ 11 and RJ14jacks may be equal in size and appearance and both
may contain 4 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 lines for your MFC.
Converting Telephone Wall Outlets
There are three ways to convert to an RJll receptacle. The first two ways
may require assistance from the telephone company. You can change the
wall outlet from one RJ 14jack 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 tLll4 wall outlet. It will separate the
wires into two separate RJll jacks (line 1, line 2) and a third RJ14 jack
dines 1 and 2). Plug the fax machine into L2 of the triplex adapter.
