Connecting the Telephone and Modem
Your computer is equipped with a single modem port to connect the internal modem with a telephone wall jack. To use the
wall jack for both telephone and modem lines, purchase an additional RJ-11 phone cable and a "1-to-2" port adapter device
(splitter).
To connect the modem
1 Unplug your telephone from the wall jack and set aside.
2 Plug another phone cable (not supplied) into the modem port on the back of the computer.
3 Plug the other end of the cable into the wall jack.
