If you need density along the Arris line, skip the C4 and go straight to the E6000.

Hey Colton, 

We’re using small 16 channel CMTS systems for residential MDUs and colocating them directly on premise inside of wiring closets and then connecting them by metro ethernet.  We’ve had great successes so far with this model.

There’s lots of CMTS vendors.

There’s tons of used Motorola BSR 64Ks on the market, but be aware of the lack of useful IPv6 features (like prefix delegation) in older software releases.  If you buy a box and want to run 7.x or 8.x, you’ll need to relicense your downstream and upstream channels at some additional arbitrary fixed cost.  

I’m personally fond of these things:

You can only bond 16 channels together max though because that’s all the box supports and you can’t bond across boxes; however, these things are less than 4 grand if you buy them in bulk so they’re really fucking easy to just spam everywhere.

Blonder Tongue makes a pizza-box style CMTS too:

As does Harmonics:

All three are based on the same chipset, so the real differentiation is price and firmware features.  

Then there’s Cisco.

The UBR is a popular platform.  And pretty soon there’s going to be a glut of UBR10Ks on the Market because Comcast is busy ripping their UBRs out of production because they’re upgrading their cable plant to the CBR platform.

Then the Arris C4, if you have deep pockets, is a modern version of the BSR:

We have looked and are very familiar with the multiple technologies that work over phone lines namely VDSL2 and G.FAST. However, using the coaxial cable seems to be a much better solution than using the phone wires.
