Can I use the Belkin Rev B battery backup with the Arris NV599?
We have AT&T U-verse with Internet Basic 6 and Unlimited Phone. No TV or VoIP. AT&T recently upgraded our gateway to the Arris NVG599. If I install the gateway's internal battery at a cost of $40, I understand that it will only power a phone when there's a power failure, and will drop all Internet connections.
We have a 14 kW standby generator that powers the whole house, but it takes 5-10 seconds to come online, and will thus interrupt our Internet service. However, I still have the Belkin Rev B battery backup unit from the previous installation (which prevents such an interruption) and would like to use it with the Arris NVG599 to bridge the generator startup gap.
I've looked at the Belkin specs and can't see any reason why it wouldn't work. The plug polarity is the same (a line over three dashes), and the Belkin has plenty of power. Would this be OK?
