The : phone line may run parallel to a flourescent light, an electric power run, or : a motor (furnace?). : The solution is to find and fix the induction problem, or re-run the phone : line to the extension. Try to have the phone line cross power lines at a 90 : degree angle where possible. The phone line runs for MILES right under power lines where they are subject to the same induction. Then when it gets into the dweeling the lines often run along the same paths as the power lines. Asking that the phone line run perpendicular to the power lines is pointless. The normal phone lines (properly balanced) will not be affected by this. THe problem must be solved by finding the imbalance. : Mark -- #======P=G=P==k=e=y==a=v=a=i=l=a=b=l=e==u=p=o=n==r=e=q=u=e=s=t======# | John Lundgren - Elec Tech - Info Tech Svcs. | jlundgre@delta1 | | Rancho Santiago Community College District | .deltanet.com | | 17th St at Bristol \ Santa Ana, CA 92706 | http://rsc.rancho| | My opinions are my own, and not my employer's. | .cc.ca.us | | I have gone out to look for myself..
