<div>A couple of days ago, we implemented IPT at a site that was
previously using a Norstar system. After conversion to IPT,
the site has been experiencing radio across all their phone lines that
terminate to an FXO card in a 2811. There is a radio tower
approximately 1 mile away from the branch. We have taken the following
actions to try to resolve this issue. </div>
<div> </div>
<div>From the Dmarc, we validated no radio was coming into the branch.</div>
<div> </div>
<div>We eliminated any bridge taps and created straight run (Cat5
cables) from the Dmarc to the router FXO ports. </div>
<div> </div>
<div>We added ground wire from the router to a nearby water pipe.</div>
<div> </div>
<div>We went through each phone line and eliminated the thought of
one of the lines causing the issue. </div>
<div>Does anyone have any other suggestions that we can
try? Interesting that we did not experience this problem on the
Norstar.</div>
