There is potentially going to be an external shielded (I hope) power cable from roof solar panels crossing at 90 degrees our incoming telephone line on the external wall. Or possibly crossing on the interanl wall while phone line is on outside wall. Is there any likely hood this will degrade our broadband/telephone service. The phone wire on the outside wall is the BT one from telegraph pole so not much I can do to protect it from interference i dont think .
Any thoughts or commenbts most appreciated
