Foreign exchange service
In telecommunication, a foreign exchange service (FX) is a network-provided service in which a telephone in a given local exchange area is connected, via a private line, to a central office in another, i.e., "foreign", exchange, rather than the local exchange area 's central office.
To call originators, it appears that the subscriber having the FX service is located in the foreign exchange area.
