Power Outage – Everything You Need To Know About Battery Backup

Home Telephone Service

In past years your home telephone was not affected by power outages. Your ability to make and receive calls would remain intact. However, newer fiber-connected homes now require battery backup power to continue functioning during a power outage. Battery backup will preserve your home’s ability to call 911 emergency services in the event of a power outage.
