Case H: Shared voice/fax line with computer modem
There are two different ways to set up the device with your computer based on the number of phone
ports on your computer. Before you begin, check your computer to see if it has one or two phone
ports.
NOTE: If your computer has only one phone port, you will need to purchase a parallel splitter
(also called a coupler), as shown below. (A parallel splitter has one RJ-11 port on the front and
two RJ-11 ports on the back. Do not use a two-line phone splitter, a serial splitter, or a parallel
splitter which has two RJ-11 ports on the front and a plug on the back.)
