In telephony, a Foreign exchange station (FXS), is a telephone interface that supplies battery power, provides dial tone, and generates ringing voltage. A device that connects to such an interface contains a foreign exchange office (FXO) interface and could be a standard analog telephone or a private branch exchange (PBX) to receive telephone service.
Any telephone exchange is an example of an FXS, as is the telephone jack on the wall, though the term is rarely applied except in connection with foreign exchange service.
An FXS interface utilizes an FXO protocol to detect when the terminating device (telephone) goes on-hook or off-hook, and can send and receive voice signals.
An FXS interface provides service at the "station" end of a foreign exchange line.

Famous quotes containing the words foreign, exchange and/or station:
“Don’t use that foreign word “ideals.” We have that excellent native word “lies.””
—Henrik Ibsen (1828–1906)
“We shall exchange our material thinking for something quite different, and we shall all be kin. We shall all be enfranchised, prohibition will prevail, many wrongs will be righted, vampires and grafters and slackers will be relegated to a class by themselves, stiff necks will limber up, hearts of stone will be changed to hearts of flesh, and little by little we shall begin to understand each other.”
—General Federation Of Women’s Clubs (GFWC)
“I introduced her to Elena, and in that life-quickening atmosphere of a big railway station where everything is something trembling on the brink of something else, thus to be clutched and cherished, the exchange of a few words was enough to enable two totally dissimilar women to start calling each other by their pet names the very next time they met.”
—Vladimir Nabokov (1899–1977)
