Cisco Voice Interface Cards (VICs) support voice technologies. VICs can be installed in interface card slots on supported Cisco access routers or in 1- or 2-slot voice network modules that are installed in network module slots on supported Cisco access routers. A Foreign Exchange Station (FXS)/Direct Inward Dialing (DID) interface connects directly to a standard telephone, fax machine, or similar device. This interface supplies ringing voltage, dial tone, and so on to the station.
