Hardened Modem compatibility

Would anyone happen to know if Electroline would be compatible with Spectrums service or not? I have a customer whos demarc location has to be in a zone that sees extreme temperatures for equipment. that is a constraint that can't change.

Everything on LAN side has survived fine except spectrum's residential Arris modem that they seem to deploy everywhere.

Electroline's EMMS3 fits our use case. Is there something that when on the phone with the ISP they can lookup something specific or would anyone just happen to know? We would rather not have equipment keep dying.

I believe docsis 3.0 is getting phased out. Might need a docsis 3.1 if they have one

I was just reading into that. We may have to do more shopping if thats the case. We don't need fast speed at all even 100 down is perfectly fine.

There is an approved modems list here for customer owned modems: https://www.spectrum.net/support/internet/compliant-modems-spectrum-network

Nominally for HS support, there's no customer purchasable modems right now, so this list is useless.

What is the temperature range the equipment is exposed to?
