We picked up a new customer that had a Norstar system that took lightning damage.
That got me to wondering so I'd like to start a discussion to get opinions as to what is the best lightning protection for a 3300.
Generally a good UPS will catch surges on the AC source, but what about the copper trunks and PRI trunks, etc.
How are you handling the protection of theses?
Also, do you consistently ground all controllers, ASU's, NSU's, etc? And to what do you ground these to? Or do you rely on the grounding on the AC power plug?
