[asterisk-users] interesting comment. New Physics?
While browsing about, found http://www.voip-info.org/wiki/view/TDM400P, where I found this comment: "Here's a tip passed on from an old telephone engineer. Where your copper 2-wire cable approaches the building, underground, finish with several large loops, about a metre in diameter, laid on top of each other. Fast moving, high energy spikes will spin off the outside of the loop as they speed into your installation, reducing the amount of energy your spike trap has to absorb. The coil shouldn't have enough loops to create any induction effects." I am grateful for this introduction to the New Physics. Just be sure not to stand on the periphery of the loop, when lightning strikes nearby. <g> joe a.
For fiber installations, be sure that your loops are not placed where flashes will distract drivers or people performing potentially dangerous activities. --Don Don Kelly PCF Corp People Come First 651 842-1000 888 Don Kell(y) 651 842-1001 fax -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of joea at j4computers.com Sent: Saturday, January 24, 2009 4:26 PM To: asterisk-users at lists.digium.com Subject: [asterisk-users] interesting comment.
