Battery backup units for digital phone services

Your digital phone service will not work in the event of a power outage unless you have a battery backup.

Electrical power is required for non-line-powered voice services to work. This includes Brightspeed Digital Voice. If there is a power outage, the services will not process calls, including those to Emergency 911.

With active batteries, the BBU will provide temporary power during an outage, allowing basic voice services to keep functioning, including the ability to dial 911. Please note that in the event of an outage that impacts the internet network as well, the BBU may not guarantee functionality.

Important information about BBU

In case of an electrical power outage, a BBU should last at least 24 hours in standby mode. While under BBU power, you may not be able to access the internet. Other services, such as security alarms, may not work.

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.

IMPORTANT: Failure to maintain your BBU may result in loss of voice service during a power outage, including a loss of access to Emergency 911 and other services.

You can find battery backup units from Precision Power Solutions, or from many other retailers.
