Query: Hope it works when the time comes

Though we have two whole-house surge protection devices (redundant system), the phone line is a backdoor into much of our equipment. Not remembering where I got my old device, and not being sure it was still operational, I purchaced the APC Protectnet PTEL-2 to get us current with telephone/DSL protection. It installed easily enough.I do think I'll be researching hardwire versions for the main panel, with some type of LED indicator that it is actually operational. This will work for now and, if I'm reading the documentation correctly, if this device takes a strike it will disconnect the phone line. In other words if the phone dies, the device did its job and I'll have to buy another one.
