Your service has a Battery Back-up Unit (BBU) located inside your garage or house where it can be easily monitored. If your ONT is accidentally unplugged or the power goes out, your back-up battery will provide you with power for voice service for up to 8 hours. (Note that it will not operate your Internet service or router.)
The BBU contains a series of indicator lights that tell you whether your service is being powered by your home's electricity or the battery. If you are experiencing trouble with your phone service, check your BBU. A green light indicates that your BBU is operating normally. A yellow light means it is operating on battery power. If the light is not lit, check that the unit is plugged in. A red light or a low-battery alarm indicates that the battery is not connected or needs to be replaced.
