That is the UPS/Power supply for an external device such as a Fiber ONT or an iNID. If you no longer have anyAT&T services, then you could do as baseballisback suggests.
Normally you're asked to keep it in place in the event you, or a later home owner, wants to use it. There is the slight concern that you could kill the batteries by allowing them to fully discharge, but the batteries are probably dead by now anyway. Furthermore, AT&T would probably want to redo the installation.

What other AT&T services do you have?
Unplug it. Wait a few minutes. See what happens.

I have no AT&T services here. I unplugged it. It gave a long beep and nothing else. Thanks for your help.
