AMP account with C2

I’m currently trying to set up an AMP account and possibly apply for TOS. I’m at the point in the new account process in which I have to set up a live trading platform. There were many options so initially I choose CGQ, for no paerticular reason other than trying to get to the end of the application process. However today I noticed as I got farther into the process, there was an option to select C2 on the AMP side of the configuration. I’m wondering if I need to set it up that way for TOS? I understand the C2 side of things, I can subscribe to my own system or use broker transmit but I don’t understand the AMP side of things. I’ll probably explore both C2 options, however I’m still not sure what if anything I need to do on the AMP configuration side of things. Appreciate any help!
