Power Outage Your FiOS Digital Voice service requires electrical power to function. In case of a power outage, the Battery Backup Unit (BBU) will power your basic FiOS Digital Voice services—including 911 dialing—for up to 8 hours if a fully-charged battery is inserted in the Unit. Note:
  • If the battery is exhausted or there is no battery present, the Service will not function for any purpose.
  • If your home security system is currently using a jack in your house, those same jacks can be used for FiOS Digital Voice without impacting security services; however, in the event of a power outage, the power limitations apply to your alarm system.
  • The BBU will not power your internet services, television services, or computer. You are responsible for purchasing and/or replacing the battery in the BBU.
  • View the  PowerReserve Battery Backup Unit Installation Guide.
Need to Cancel If you ever need to cancel your FiOS Digital Voice, please call Customer Service at 1.800.921.8101.
