[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. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of j...@j4computers.com Sent: Saturday, January 24, 2009 4:26 PM To: asterisk-users@lists.digium.com Subject: [asterisk-users] interesting comment.

To be fair they did specify underground ;) j On Sat, 24 Jan 2009, Don Kelly wrote: 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-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of j...@j4computers.com Sent: Saturday, January 24, 2009 4:26 PM To: asterisk-users@lists.digium.com Subject: [asterisk-users] interesting comment.

I would make the loops tighter, and the point is it acts like a choke, especially in shielded cable, but you would want your network protector or ground on the outside of it, not the inside, so putting outside the building is not that great an idea.
