Battery Backup for Voice

Frontier Digital Voice service needs your home's electricity to work. If you lose power, a Battery Backup Unit (BBU) can power your phone so you can make phone calls—including emergency 911 calls.

To get this protection, order a Battery Backup Unit for your service. Installing a BBU is optional for all Frontier Digital Voice customers. Battery backup provides access only to your Frontier Digital Voice service during a power outage. It does not power your Frontier internet or TV service.
