Scott, Have any idea which exact vendors and model numbers are within this price range? So far I have just found mini CMTS systems like the Pico and Harmonic's. Both of these are a 16x4 configuration, but no mention of remote MAC+PHY nor DOSIS 3.1. Then their is Huawei's solution, but still I think that's more based on C-DOCSIS. Searching the vendors websites you recommended show no results for remote MAC+PHY in a small format.
