Ports 2,3,and 4 on CM1200

I'm new here, so maybe someone can help me understand the purpose of ports 2,3,& 4 on the CM1200.  I had hoped to use these ports to send a signal directly to my TV (using Apple TV) and a LAN switch ...

    A modem isn't the correct devices if you're wanting multiple devices connected. A modem/router is the correct device. 

    Or go modem----router----switch. 

    The cm1200 confuses a lot of people and there isn't good education done on it from netgear or isp's. Half the problem is that there are ISP's that support multiple public ip addresses. in those cases you can hook multiple devices to it. But those ISP's are rare. the big 3 (comcast, cox, spectrum) don't support more than 1 public ip address unless you pay for it or have a business class line.
