No phone service with power outages - Time Warner Internet

This question is about "No phone service with power outages", with Time Warner Cable internet and apps. My area had many power outages (6+) over the past few months. My mother is 94 years old and depends on the phone as a lifeline. We have a backup UPS on all phone equipment and the phone never works. The same thing for our neighbors with whole house standby generators. I have contacted Spectrum support who were of no help. I understand the possibility of tree limb or other event may also cut the cable line but that is not the issue. When the power fails the Spectrum equipment isn't being protected by a standby UPS or backup generators. The village of Treadwell NY does not have cell service available. We are totally dependent on the phone for fire and other emergency services. What can be done to resolve this issue?
