Connecting Cisco 4-Port FXS/DID Voice Interface Cards
Revised: April 15, 2008, OL-15695-01
This document provides an overview of Cisco interface cards and explains how to install the Cisco 4-port FXS/DID voice interface card (VIC3-4FXS/DID). It contains the following sections:
For an overview of Cisco interface cards used for Cisco access routers, see the Cisco Interface Cards for Cisco Access Routers document.
These HWICs can be configured using the Cisco command-line interface (CLI). The CLI conforms to code 508 because it is text based and it relies on a keyboard for navigation. All functions of the router can be configured and monitored through the CLI.

4-Port FXS/DID Voice Interface Cards
This section describes 4-port FXS/DID interface cards and how to connect them to a network.
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.
Figure 1 shows the Cisco 4-port FXS/DID voice interface card.

Note Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image support. Access Cisco Feature Navigator at http://www.cisco.com/go/fn. You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear.
Before connecting a VIC to the network, ensure that the VIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the VIC to the network. This section describes the preparation necessary before connecting a 4-port FXS/DID VIC to the network.
Installing a Cisco 4-Port FXS/DID Voice Interface Card
Install the Cisco 4-port FXS/DID VIC according to the instructions in the Installing Cisco Interface Cards in Cisco Access Routers document.
Caution WAN interface cards and voice interface cards are not interchangeable. Voice interface cards cannot be installed in a WAN interface card slot or in a 2-slot WAN network module. To prevent damage to the card, confirm that the slot or network module that you intend to use supports the VIC that you intend to install.
Ensure that the equipment you are working with is properly grounded according to the instructions in the Installing Cisco Interface Cards in Cisco Access Routers document.
Use a standard straight-through RJ-11 modular telephone cable to connect a VIC3-4FXS/DID to a telephone or fax machine.
Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call. Statement 1042
Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: FXS. Statement 1044
Connecting Cisco 4-Port FXS/DID Voice Interface Cards
To connect the Cisco 4-port FXS/DID VIC, follow these steps:
Step 1 Confirm that the router is turned off.
Step 2 Connect one end of the straight-through RJ-11 cable to an RJ-11 port on the card. (See Figure 2.)
Note Ports on this interface card are colored gray.
Figure 2 Cisco 4-Port FXS/DID VIC (VIC3-4FXS/DID)
Step 3 Connect the other end of the cable to the RJ-11 port on the telephone or fax machine.
Step 4 Power up the router.
