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 iÄ-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 fax 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 fax 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.
