Looking to temporarily Kill My DSL internet?

K so, im trying to disable the internet DSL in my house, without calling the company. Im trying to do this secretly too, so that noone else in the house finds out. Now, what i know is the internet runs thru the phone line, right? So can i go to the phone box, and disconnect certain wires? do i have to kill the phone line in the process? I could go into a huge detail as to why im doing this, but that would be a waste of time,
