We have a similar version of that panel in our house. However ours has separate Cat5 and Telco/RJ14 wiring, along with cable distribution.

Anyway, yes, you can do exactly what you are thinking. For example, in our home the cable modem is in my office. The cable modem goes into a wireless router there, and I take one of the ports and run it to the distribution box. At the cabinet, I take that line and run it into the upstream port of 100BT Hub/Switch, and then distribute the connection through the downstream ports to the downstairs of the house.

Downstairs we are running a combination of hard wire (into my son's server) and additional wireless.

You can also determine which wire is which by using a router at one end and the hub at the other. You'll get a port connect light on both sides if they are talking.

Let me know if you need more detail...
