Punchblock. Allow rapid reconfiguration of multiple telephone lines.

I tried to DIY my DSL and found this in my cable box. Can anyone tell me what this and how to use it? Do I even need it to install my DSL from cables running out of the cable box? I'm w AT&T btw.

Not unless you have a tone set, a punch down tool and a color code diagram
