Internet access: dsl cable to ethernet in the router

Can I access to internet by using not the RJ11 to RJ11 cable, but a cable RJ11 to RJ45, namely a cable with a dsl tip and an ethernet tip like this?

I didn't find a solution of this type on the web; I want to know this information only for curiosity.

Solution 1:

If you mean directly connecting the phone line to your Ethernet router, no it won't work. You might even damage your router! DSL has voltages, rates and protocols which are completely incompatible with Ethernet. You need an DSL modem to convert the DSL signal to an Ethernet signal, which you can then feed into your Ethernet router.
