Only modems on the approved list are guaranteed to work and be supported. While the SB8200 isn't actually on the list, most people in legacy TWC areas seem to be able to activate it just fine on all tiers up to 300/20.
@DR_Stranger_Who At this time there is no option to use your own modem for our Gig service. The SB8200 is not on our approved list. I would highly recommend not attempting to use that modem on our network.
