Hey Colton,=20
We=E2=80=99re 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=E2=80=99ve had great =
successes so far with this model.
There=E2=80=99s lots of CMTS vendors.
There=E2=80=99s 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=E2=80=99ll need to relicense your downstream and upstream channels =
at some additional arbitrary fixed cost. =20
I=E2=80=99m personally fond of these things:

You can only bond 16 channels together max though because that=E2=80=99s =
all the box supports and you can=E2=80=99t bond across boxes; however, =
these things are less than 4 grand if you buy them in bulk so they=E2=80=99=
re really fucking easy to just spam everywhere.
Blonder Tongue makes a pizza-box style CMTS too:

uro-docsis/
As does Harmonics:

All three are based on the same chipset, so the real differentiation is =
price and firmware features. =20
Then there=E2=80=99s Cisco.
The UBR is a popular platform. And pretty soon there=E2=80=99s going to =
be a glut of UBR10Ks on the Market because Comcast is busy ripping their =
UBRs out of production because they=E2=80=99re upgrading their cable =
plant to the CBR platform.
Then the Arris C4, if you have deep pockets, is a modern version of the =
BSR:
