ethernet and phone cord?

those are two completely different cords, if it's dsl then you connect one side to the wall, one side to modem, then the ethernet cord goes in modem next to the phone cord. if you had a cord that connected a phone cord to an ethernet cord it wouldn't work anyway, as you need a modem to convert the data into the right type that a computer can understand.

Big Ben has the right answer...in ethernet, there are 8 twisted pairs of wires and phones (anaolog) there only has to be 2

No,you'd need to buy a specific adapter,or have the right equipment. Services that use DSL tend to use these,and you can usually patch them through an Ethernet router.

Those are custom made cables more for phone systems installer contractors. Your cost on a cable like that will be expensive. your better off making your own or I know these guys can make it for you.

If you make it yourself just get the pin out correct and your cool.

a DSL twine isn't comparable to a telephone cable. a DSL cable easily has a bigger head than a typical telephone cable. no longer something will ensue once you place a telephone cable in replace of a DSL cable.
