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?

AT&T phones

Voice/Internet Modem
Brand: CISCO
Model: DPQ3212
Input Voltage 100-120V AC / 50-60 Hz

    Hi HalVegas, assuming the Cox equipment that provides the network signal to your home was unimpacted, there are two things required for your home phone line to work: the digital telephone modem must be connected to both an active coax cable outlet and a source of power like an external battery backup. Does this help?

    HalVegas  It's my understanding that the backup battery will work for telephony services only.

      Thanks for your reply. So, are you saying that the Cox battery backup units are for telephony services that do not involve modem provided voip?  If I get power battery backup units (not Cox units) for the modem and telephone equipment that will suffice to maintain telephone service in a power outage?
