You can not use UTP/STP interchangeably with phone lines, a phone line has 4 wires, UTP/STP has eight wires twisted, it is physically impossible, unless you cut and tip the Ethernet yourself with an RJ-11 instead of an RJ-45 which seems way above this users level.

The DSL modem should allow an input cable (which will be a telephone line), and the output from the DSL modem to the computer will be an Ethernet/LAN/Cat-5, or Cat-5e cable. The output from the DSL modem then connects to your computer. This is how it would look:

Phone Jack -----DSL Modem======Computer

On all your other devices is will go like this:

Phone Jack ------filter------home phone
Phone Jack ------filter------fax machine
Phone Jack ------filter------any other phones

Where the single dash is phone line, and the double dash or equal sign is networking cable/Ethernet cable/Cat-5 or Cat-5e cabling.
