Explanation

Foreign Exchange Station (FXS) provides a connection from a switch to an analog endpoint device such as traditional telephones or fax machines. It provides line power, dial tone, and ring voltage.

Foreign Exchange Office (FXO) allows a switch such as a PBX to us a standard analog connection (FXS) from the PSTN or from another switch. In this case the PBX is emulating an endpoint device. Because this is a standard endpoint connection it uses two-wire connections just like a standard phone and often uses an RJ-11 connector interface.
