With ATT Uverse I had the experience of adding common mode chokes (#31
ferrite) on a long run of cat 5 and having it knock down the desired

My problem is that when I try to operate on 160 the DSL
crashes. I have tried many Type 31 3 inch ferrite rings
with 20 turns on both the phone line and the Cat 5 cable
from the Zhone modem but even at 200 watts the
