FXO ports are only for CO trunks to be connected to the system. They do not generate voltage, they expect to receive it from the phone system. There's a myriad of additional technical details that can be added for a better explanation, but basically FXO ports are for connections to the Telco, and FXS ports are for connecting analog devices to the system.

Hope this helps,
