Lightning Protection - 05/22/19 01:53 PM
I have a customer with an NEC SV9100 (School) That get hit with Lightning 1 to 2 times a year which blows out (2) of the 16 port digital station cards that are connected to another building
The phone system was installed in 2015 (Spring)
They didn't start having problems until summer of 2017 (They got hit once knocked out (2) Station cards going to another building they also had some other computer devises get damaged
Then again in summer of 2018 (2) Times
Then yesterday in 2019
Keeps blowing out the same 2 cards (which causes the whole system to be flaky until you pull the cards out
There is Lightning protection on this 100 Pair cable which is grounded my question is how can I tell what kind of lightning protection is installed I am thinking its not for digital phones
I am assuming that its for analog its been installed for a while
it just says Lucent Technologies on the cover
looking for some suggestions
Thanks
