Ive had lightning issues much like David.... three hits in 2001 (with in
60 days) cost us $45,000.00 in damages. Had engineers from the telco
(Verizon) look at it, they in turn sent specialists out. No one change
seemed to fix the issue; however one of the last things we tried was
having an electrician torque the incoming power lines (in the fuse
pannle) to the recommended values, and added a Belkin Surgemaster
(F9G934-10) to every PRI/network connection the is.

Never lose the D-Channel anymore....

Hope that helps!
