ASUS gets their butt handed to them by the feds

@Dashrender Right, just seeing if people were using anything in addition to it. So as far as the POE pass-through... What do I need to get to power a UAC AP?

I think we need someone with experience to weigh in on how this works. From my knowledge they use a DHCP-esque system and do MAC reservations to set addresses. @PSX_Defector may have some inside knowledge though. Certainly TWC hasn't, at least to my knowledge, logged into the modem to set it up. They get the MAC address then plug it into the network.
There are multiple systems at play, but you are for the most part correct.
The start of everything is CMTS. Most people are using Cisco CMTS boxes nowadays, although I really only deal with TWC and Comcast for the most part. People like CableONE or Mediacomm might do things differently. But from my experience, most of the systems are fairly similar from different vendors.
The CMTS has a private VLAN'd network, 10.x or something like that, which sends traffic across for authentication and provisioning. This encompasses much of the newer environments within cable systems. It also handles things like CableCARD and set top boxes.
There are two things CMTS looks at to determine what it needs to do. The MAC and the serial. MAC address is obvious, need it to fetch an IP. The serial then determines if the device is allowed onto the network. From there, it will establish the allowed services; internet, HBO, or like at my house all the porn channels. This sends the token over to the device to allow it to descramble whatever it is accessing. Internet access is given the go-ahead to talk to the public VLAN, read if there is a lease on the MAC already, then issue an IP out.
This is usually the only thing that the ISP does. Very few actually configure the device beyond that. Many don't even have access to that side of the device. Some vendors do, like Pace or even Arris. But only very limited things.

Awesome explanation. Thank you!

Here's what it looks like now. Ignore the eth dialog box, it was stuck there for some reason. The second image is the wizard you run through. It's really easy to set up.
What OS distro is that? Looks good.

Fedora 23 with Gnome 3.

Sneaky way to promote Linux desktops.
