: It may be a problem with the way the wiring is run for the extension.  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.
