Hi Colton, For what it sounds like you’re really looking for, a remote MAC-PHY (or pre remote MAC-PHY, ala mini CMTS) would probably be the good fit for your application. This is certainly not an endorsement, as we haven’t used any remote MAC-PHY devices today. There are a couple players pouring money into products that haven’t really been mentioned yet... 1) Huawei - which initially brought a mini CMTS to market (D3.0, 16x4.) Some C-DOCSIS stuff, so may be feature poor but it doesn’t sound like you really need the boatload of features that are in a classic full-size CMTS anyway. Not sure what’s going on with their D3.1 remote MAC-PHY general availability is either. 2) Gainspeed - D3.0/D3.1 product (not sure about where the generally availability of their product lines are) but if you happen to be a Juniper customer, they partner with Gainspeed so it can be easy to get engaged with them.

Colton, You're only going to find very small, old, or not certified (usually still very small) CMTSs that only do layer 2. All of the major vendors are doing layer 3 because we've found out over time that not doing it is more problematic. Having said that, if you're looking for a more ONT/DSLAM type of install there is a new type of CMTSs that look at lot like traditional telco DLC/BLC deployments. https://intx15.ncta.com/wp-content/uploads/2015/05/17-Remote-PHY.pdf The remote PHY+MAC boxes are basically mini-CMTSs and they typically rely on something upstream handling layer 3. The remote PHY boxes are different as they don't even do a complete layer 2 and instead forward DOCSIS frames back to a centralized CMTS/CCAP.

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.

I've demo'd one ofthesmall 1/2RU C-DOCSIS CMTSs, and they certainly work. For us though itwasa non-starter as we needed support for DSG and it didn't have it. Ifallyou are after is basic internet connectivity there is Pico Digital,Vecima,Sumavision, as well as others. Many of the C-DOCSIS CMTSs seem eitheronlysupport, or are more often meant to support layer 2 operations wheretherouting happens upstream from the CMTS.

I would liketoknow 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 phonewire, orcoaxial 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 usingthephone wires. So I am looking for compacts, low cost CMTS systems. Based on thespecs, Iam looking for something at least DOCSIS 3.0 capable, with at least16X4output. Something with the ability to upgrade to software upgrade toDOCSIS3.1 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 chassisbasedsystem to feed an entire town with. So far I have found the http://picodigital.com/product-details.php?ID=miniCMTS200a which seemstoretail for under $5000.
