Battery backup for Connected Voice

Connected Voice phone service will not work in the event of a power outage unless you have a battery backup unit (BBU).

Electrical power is required for Connected Voice service to work. If there is a power outage, the service will not process calls, including those to Emergency 911.

With active batteries, a BBU for your phone equipment will provide temporary power during an outage. This allows your phone service to continue functioning, including the ability to call 911.

Battery options

Please note that the BBU is not covered by our Inside Wire Protection plan.

Important information about battery backup

In case of an electrical power outage, a BBU should last at least 24 hours in standby mode.
Other services, such as security alarms, will not work if they do not have their own battery backup.
You are responsible for obtaining, monitoring, replacing, and properly disposing of the BBU and all batteries for it.
We recommend that you check the BBU at least twice a year to ensure it is operating and ready to use in case of a power outage.
