Anyone know what this box is for?

First of all, I live in the Marion County area of Tennessee. We had a tree fall into our yard, when it did it pulled down all the power, phone, cable and fiber optic lines. We have had our local power (SVEC), local internets (SVEC Connect and Spectrum) and phone (AT&T) companies out to fix their lines.

We now have one line that is hanging way to low and no one claims the line. The box it is attached to (as shown in the picture) is what makes it different than the rest. I'm thinking a cable line, but that is no confirmed.

Anyone have any clue what service or company this might be for?
