Battery Backup Units, interior-exterior
Am looking on this webpage Telephone Equipment Battery Questions and Answers (https://www.cox.com/residential/support/telephone-equipment-battery-questions-and-answers.html), Battery Backup Units on the Outside of the Home and units connected to ONT. Both units appear to connect to the cox cable. Is this necessary to maintain phone service during a power outage. Could standard battery backup units that allow all of the equipment (modems, phones, etc.) to be plugged into them work as well without the units that the cable plugs into or are the units that the cable plugs into necessary to maintain the phones during a power outage?
