A Foreign Exchange Station (FXS) interface connects directly to a standard telephone, fax machine, or similar device and supplies ring, voltage, and dial tone. The Cisco FXS interface is an RJ-11 connector that allows connections to basic telephone service equipment, keysets, and private branch exchanges (PBXes). The VIC-2FXS-EU voice interface card is intended for use in Europe. In countries where PSTNs do not use RJ-11 wall jacks, use a suitable adapter to convert the plug on an RJ-11 modular cable to the type of wall jack connector that is used in your country.
