Cable Modem Procurement Question
When purchasing a cable modem, I know that the Number 1 X Number 2 (i.e. 16x4) is the downstream and upstream channels that it is capable of handling.
However, is it possible to correlate those numbers to the speed package that we are receiving? I don't want to over or under buy a device for the current tier we are on, which is 200/20.
Also, what are the opinions on DOCSIS 3.0 vs. DOCSIS 3.1? Do we really need 3.1 to future proof ourselves?

@Brad, many times ISPs bake custom configs into Modems the provide to customers.
Before you buy a modem, be sure you have the option of installing/using your own modem, rather than the ISP provided modem.
You can do this easily by opening a customer support ticket + asking your question.
Your channel numbers question for a give ISP + also a given area (as technology will vary depending on date it was initially deployed) is also best answered by the specific ISP for a specific service address. Open an ISP support ticket for this answer too.

Comcast or Charter provides a list of approved DOSIS modems. You only need to buy one that's at least the DOCSIS level you've purchased.
