for belkin, recommeded to use the modal have allow Tel line connection before going into Modem. I hit twice and only replaced the Modem Power adapter and the rest euipment all OK.
Before used the modal, I use the one without Tel protection, end up Modem / cordless all KO.
Now even better after moving to UNIFI....no surge will came from the Tel line anymore since it use fibra...hahaha

I was thinking of the possiabilities of having a so called "Power Stabilizer Unit" for home use install, to protect and have a stable electricity included of $$$ saving.
Where it place right after the main meter type and could plan in the ELCB box
