[comp.dcom.telecom] Hum in the line

Regarding the humming noise in the line after an electrical storm: It sounds
like the surge arrestors in the network interface box (or upstream) are blown.
In any case, it's easy to check out. Get a neighbors phone and plug it in
to one of your jacks. No hum, phone problem. Still hum, find network interface
box. Most newer ones have a customer removable cover and a test jack. Plug
good phone in test jack. If you still hear hum, it's in the network so
call the phone company. If you don't have a test jack, call the telco. They
will tell you where the problem is...
