Arris Cable Modem Teardown
Former ARRIS employee here and part of the team that wrote the DOCSIS HMS-MMM specification.  Here&#x27;s a link to the specifications for version 3.1 - <a href="https:&#x2F;&#x2F;www.cablelabs.com&#x2F;specifications&#x2F;search?category=DOCSIS&amp;subcat=DOCSIS 3.1&amp;query=&amp;doctype=&amp;content=false&amp;archives=false&amp;currentPage=1" rel="nofollow">https:&#x2F;&#x2F;www.cablelabs.com&#x2F;specifications&#x2F;search?category=DOC...</a>.  Understanding how these devices work will make understanding the software much easier.  I will warn you however that most of the magic is in the hardware.  Also note that the surfboard line originated at Motorola.
