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 Arris SB8200.

It has one coaxial F connector for connection to a cable network (5-204 MHz US; 108-1002 MHz DS),

and two RJ45 ports which are implemented differently depending on the vendor.
