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 fax machine 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
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.
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 fax machine must be plugged into an RJ11 jack. RJ11 and RJ14
jacks 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 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 outlet 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 wall outlet. It will separate the wires into
two separate RJ11 jacks (line 1, line 2) and a third RJ14 jack (lines 1 and 2). Plug the
fax machine into L2 of the triplex adapter.
