How do you adapt a phone jack to fit the phone cord?

I have a phone jack in a bedroom but have never used it. Now I want use that phone jack for my DSL line but the phone cord for the DSL line doesn't fit. The phone cord seems too big to fit into the jack. Do I have an old jack and newer cord? Can the jack be adapted to fit the phone cord?

Hi, For what I understand you have a regular phone jack ( rj11 ) and your dsl modem has a ethernet or network jack ( rj45) so you CAN´T use your telephone jack with the ehternet jack. Your phone jack has 2 or 4 wires, where as your ethernet jack has 8 wires and they are used for totally different things. I hope this answers your question.
