backup battery for BGW320

I have only a  BGW320 gateway box inside my house,  the ONT on the back of the gateway is not connected.   I have a AT&T Fiber 300 plan with VOIP phone . 

Attached are the photos for the outside (of my house) AT&T network connection and inside BGW320 connection. Do I have a ONT ?

I am looking for a back up battery for my gateway. Is CP12142LI :

Network UPS 12Vdc. Lithium Battery,19500mAh, BMS, 4LED

a good choice ?

Thank you for your attention and help.

Hey there shuilu, we'd be happy to help you with your ONT and battery backup inquiries!

 

Visit our webpage for learning about AT&T Internet equipment to get more  information about the ONT. We install an ONT when Internet is first set up. You should find it outside your home or inside your garage, closet, or utility area, not on the back of the gateway. We don't see the photos you mentioned, so we're not sure exactly what you're working with right now.

 

When it comes to getting a battery backup for your gateway, please check out our website to see what's available and which one will work best with your gateway.

 

If you have any other questions about your ONT or getting a battery backup, just let us know!

Hello ATTHelp, The website referenced for "battery backup for your gateway" does not list the BGW320
