The Adtran 411 is your optical network terminal, or ONT. Essentially, it functions as a modem by providing Gigabit Ethernet as well as a POTS (Plain Old Telephone Service) phone jack. The ONT is generally located indoors, and must be adjacent to a power outlet. In some cases it's placed in a box on the outside of the home.
|Power||This LED verifies power is getting to the device.|
|Fiber||This light will remain solid green while the connection between the ONT and Sonic is established. If the light is off, the ONT is not making the connection. If the LED is switching from green to red, then light levels are far below what they should be.|
|LAN||The LAN light will blink to signal an active connection.|
|Voice||This indicator will go solid green when the voice line is in use.|
One side of the ONT has a 12V Power port, a POTS (plain old telephone service) port and a Gigabit Ethernet port, as shown in the image below. If you ever have connection problems, a good troubleshooting step is to unplug the power cable from the side of the ONT for a full 15 seconds and then plug it back in. Allow a few minutes to reboot.
The other side of the ONT contains the Fiber connection and should not be unplugged, as dust can get into the port and cause connection issues.

ONT Battery Backup
With our Fusion Fiber services we offer to provide a Powertec Solutions International Model PS18L-32 for $99. The battery should provide approximately five hours of battery back-up. Do note that this battery back up only provides power to the ONT meaning you will need an analog phone in order to make phone calls and a power source for computing equipment.

What does a flashing green fiber LED indicator mean?
I don't seem to get a connection to the internet right now, so I believe it has to do with the modem. But flashing green is not in the documentation above.
