The Arris CM8200 is a DOCSIS 3.1 layer-2 cable modem approved by several ISPs and widely distributed in Australia for HFC (hybrid fibre coaxial) implementations of the National Broadband Network (NBN). Two revisions exist, A and B. Apparently the CM8200 is functionally identical to the SB8200. It has one coaxial F connector for connection to a cable network (supports 5—204 MHz upstream; 108—1002 MHz downstream), and two RJ45 ports which are implemented differently depending on the vendor.

NBN features

• On NBN units, the RJ45 ports are labelled UNI-D1 and UNI-D2, and normally on UNI-D1 is used
