Quick and Easy DSL line filter

Looking for a typical schematic for a DSL line filter?
I'm amazed at how everyone sell's em and I know they're cheap.. but I wanted to put one right in my phone.

Well here ya go!... I built mine on a PCB small enough in order to fit inside my favorite Panasonic Phone/Multi-Box Answering Machine.

  1. (2) 6.8mH Inductors
  2. (2) 10mH Inductors
  3. (1) .015uF 250-400V Capacitor (Higher is better)
  4. (1) .022uF 250-400V Capacitor (Higher is better)
  5. Some 2-wire phone cable or some RJ-11 jacks - whatever's handy.
