DSG=Docsis Set-Top Gateway.  It is a more modern implementation of the command and control communications path that tradition video set-top boxes used.

What is DSG? Yes, I am really looking for a CMTS to perform layer 2 just as our DSLAMs and GPON do today. All layer 3 will be upstream. I would want to handle DHCP upstream, but have the CMTS insert Option 82 if that is a feature. Not sure what specific CMTS stuff you need.

It really depends on what features you are after.  I've demo'd one of the small 1/2RU C-DOCSIS CMTSs, and they certainly work.  For us though it was a non-starter as we needed support for DSG and it didn't have it.  If all you are after is basic internet connectivity there is Pico Digital, Vecima, Sumavision, as well as others.  Many of the C-DOCSIS CMTSs seem either only support, or are more often meant to support layer 2 operations where the routing happens upstream from the CMTS.

Well, maybe NANOG's not a bad place for this post then! I would like to
know more about the data-only side of CMTS systems, and who the main
vendors are.

We have MDU properties where there is either old inside CAT3 phone wire, or
coaxial cable. 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.

So I am looking for compacts, low cost CMTS systems. Based on the specs, I
am looking for something at least DOCSIS 3.0 capable, with at least 16X4
output. Something with the ability to upgrade to software upgrade to DOCSIS
3.1 would be nice, but I doubt that would be a low cost solution.

Whats out there for small operators that don't want a large chassis based
system to feed an entire town with.

So far I have found the which seems to
retail for under $5000.
