Cisco Cisco Voice Interface Cards Installation Guide

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.
