The voice over IP feature enables the Cisco 2600 and Cisco 3600 series of modular routers to carry voice traffic, such as telephone calls and faxes, over an IP network simultaneously with data traffic. This document explains how to install and configure the following network modules and interface cards for these routers:
You need both a voice network module and a voice interface card for a voice connection. You can install one VIC (providing two voice ports) in a one-slot voice network module, and two VICs (four voice ports) in a two-slot module. At least one other network module or WAN interface card must be installed in the router to provide the connection to the IP LAN or WAN.
This document is intended for both data communications managers and telecommunications managers who are installing, configuring, or maintaining voice network modules and interface cards.

| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
| Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Both LAN and WAN ports may use RJ45 connectors. Use caution when connecting cables. |
| Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. |
Follow these guidelines when working on equipment powered by electricity:
| Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
The following warning applies in Australia:
| Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. |
| Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. |
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
| Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm). |
| Caution Network modules do not support online insertion and removal (hot swap). To avoid damaging the module, before you insert a network module into a chassis slot, you must turn OFF electrical power and disconnect network cables. |
The following instructions apply only to installing network modules in a chassis slot. To install a voice interface card in a network module, see the "Installing a Voice Interface Card in a Network Module" section.
You need the following tools and equipment to install a voice network module in a Cisco 2600 series or Cisco 3600 series router chassis slot:
You can install network modules in the chassis either before or after mounting the router, whichever is more convenient.
Follow this procedure to install a network module:
Step 1 Turn OFF electrical power to the router. However, to channel ESD voltages to ground, do not unplug the power cable. Remove all network interface cables, including telephone cables, from the rear panel.
The following warning applies to routers that use a DC power supply:
| Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. |
Step 2 Using either a number 1 Phillips screwdriver or a small flat-blade screwdriver, remove the blank filler panel from the chassis slot where you plan to install the module. Save the blank panel for future use.
Step 3 Align the network module with the guides in the chassis and slide it gently into the slot. (See Figure 6.)
Step 4 Push the module into place until you feel its edge connector mate securely with the connector on the motherboard.
Step 5 Fasten the module's captive mounting screws into the holes in the chassis, using the Phillips or flat-blade screwdriver.
Step 6 To install a voice interface card in the module, continue with the "Installing a Voice Interface Card in a Network Module" section. If you do not need to install a voice interface card, and if the router was previously running, reinstall the network interface cables and turn ON power to the router.
The following warning applies to routers that use a DC power supply:
| Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. |
If the router is not fully configured with network modules, make sure that blank panels fill the unoccupied chassis slots to provide proper airflow. (See Figure 7.)
Voice interface cards fit into a voice network module. The voice network module installs into the router chassis. You cannot install a voice interface card directly into the chassis.
This section explains how to install a voice interface card in a voice network module. To install the network module in a router, see the "Installing a Voice Network Module in a Chassis Slot" section.
| Caution Although voice interface cards (VICs) physically resemble WAN interface cards (WICs), which install in a Cisco 2600 series WIC slot or a Cisco 3600 series two-slot network module to provide WAN interfaces, VICs and WICs are not interchangeable. VICs cannot be installed in a WIC slot or a two-slot network module, and WICs cannot be installed in a voice network module. |
You need the following tools and equipment to install a voice interface card in a Cisco 3600 series router:
A voice network module has two slots for installing voice interface cards. These slots are numbered 0, on the right, and 1, on the left.
The FXO voice interface card includes two jumper headers, W3 and W4, to set loop-start or ground-start mode. One jumper configures each FXO port. The default setting, which should be satisfactory in most installations, is loop start. In this setting, jumpers are placed over positions 2 and 3 of headers W3 and W4.
Most modern central office equipment, such as DMS-100 and 5ESS switches, provides CPC (calling party control) and Ring on Seize on loop-start lines. CPC allows quicker disconnection, and Ring on Seize minimizes glare (collision of inbound and outbound calls on the same interface). If your central office does not provide these features on loop start, you may want to configure the FXO VIC for ground-start operation instead by moving the jumpers to positions 1 and 2.
For proper operation, both jumpers must be configured identically. In most cases, jumper setting should have little or no effect on operation.
| Caution Voice interface cards do not support online insertion and removal (hot swap). Before inserting a voice interface card into a voice network module that is already installed in the router chassis, you must turn OFF electrical power and disconnect network cables. |
| TimeSaver You can install voice interface cards either before or after mounting the router, whichever is more convenient. You can install the card in the voice network module either before or after installing the voice network module in the router chassis. |
Follow this procedure to insert the voice interface card into the voice network module:
Step 1 If the voice network module has already been installed in the router chassis, turn OFF power to the router. However, to channel ESD voltages to ground, do not unplug the power cable. Remove all network interface cables, including telephone cables, from the rear panel.
The following warning applies to routers that use a DC power supply:
| Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. |
Step 2 Using either a number 1 Phillips screwdriver or a small flat-blade screwdriver, remove the blank filler panel from the slot in the voice network module where you plan to install the card. Save the blank panel for future use.
Step 3 Align the card with the guides in the voice network module and slide it gently into the voice interface card slot. (See Figure 8.)
Step 4 Push the card into place until you feel its edge connector mate securely with the connector in the voice network module.
Step 5 Fasten the card's captive mounting screws into the holes in the voice network module faceplate, using the Phillips or flat-blade screwdriver.
Step 6 If the router was previously running, reinstall the network interface cables and turn ON power to the router.
 | Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. |
The following warning applies to routers that use a DC power supply:
| Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. |
If the voice network module is configured with fewer than two voice interface cards, make sure that blank panels fill the open voice network module slots to provide proper airflow. (See Figure 9.)
Voice network modules convert telephone voice signals into a form that can be transmitted over an IP network, and have no connectors. Voice interface cards provide the connection to the telephone equipment or network.
An FXS (foreign exchange station) 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. Ports on this interface card are color-coded gray. Use a standard RJ11 modular telephone cable to connect this interface to a telephone or fax machine.
 | Caution
Do not connect an FXS interface directly to the public switched telephone network. |
An FXO interface connects local calls to a central office or PBX. This is the interface a standard telephone provides. Ports on this interface card are color-coded pink.
VIC-2FXO is intended for use in North America. In the United States, Canada, and Mexico, use a standard RJ11 modular telephone cable to connect the VIC-2FXO voice interface card to the PSTN or PBX through a telephone wall outlet.
VIC-2FXO-EU is intended for use in Europe; VIC-2FXO-M3 is intended for use in Australia.
In countries whose PSTNs do not use RJ11 wall outlets, use a suitable adapter to convert the plug on an RJ11 modular cable to the connector used by the local wall outlet. These adapters are not sold by Cisco Systems, but are available from other vendors, such as TeleAdapt. You can obtain additional information from TeleAdapt at http://www.teleadapt.com.
| Caution Connect only a FXO interface approved for use in your country to the PSTN. Otherwise, connect the FXO interface only to a PBX. Connections from the PBX to the PSTN are permitted. |
E&M (ear and mouth) is a signaling technique for two-wire and four-wire telephone and trunk interfaces. The E&M interface typically connects remote calls from an IP network to a PBX. The next section, "Connector Pinouts," lists connector pinouts for this connection. Ports on the E&M voice interface card are color-coded brown.
| Caution
Do not connect an E&M interface directly to the PSTN. |
Voice network modules do not have connectors. FXS and FXO voice interface cards use standard RJ11 connectors. Figure 10 shows the wiring patterns for this connector, and Table 1 lists the pinouts.
| Pin | Signal |

All network modules have an enable (EN) LED. This LED indicates that the module has passed its self-tests and is available to the router. (See Figure 12.)
Each voice interface card has two IN USE LEDs, one for each channel. Figure 13 shows a voice interface card with E&M interface as an example.
Whenever you install a new interface, or if you want to change the configuration of an existing interface, you must configure the interface. If you replace a module that was already configured, the router recognizes it and brings up the interface in the existing configuration.
Before you configure an interface, have the following information available:
| TimeSaver Obtain this information from your system administrator or network plan before you begin router configuration. |
To configure a voice interface, you must use configuration mode (manual configuration). In this mode, you can enter Cisco IOS commands at the router prompt.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. (Voice interfaces do not support AutoInstall.) The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
If you have questions or need help, refer to the "Cisco Connection Online" section for further information.
To enter configuration mode, follow this procedure:
Step 1 Connect a console to the router. Configure the console for 9600 baud, 8 data bits, 1 stop bit, and no parity. Power on the router.
Step 2 If the current configuration is no longer valid, after about one minute you see the following prompt:
Would you like to enter the initial dialog? [yes]:
Answer no. You now enter the normal operating mode of the router.
Step 3 After a few seconds, you see the user EXEC prompt (Router>). Type enable and the password to enter enable mode:
Router> enable Password:
Configuration changes can be made only in enable mode. The prompt changes to the privileged EXEC (enable) prompt (Router#):
Router#
Step 4 Enter the config terminal command to enter configuration mode:
Router# configure terminal Router(config)#
The router enters global configuration mode, indicated by the Router(config)# prompt.
Step 5 If you have not configured the router before, or want to change the configuration, configure global parameters, passwords, network management, and routing protocols. In this example, IP routing is enabled:
Router(config)# ip routing
For complete information about global configuration commands, refer to the Cisco IOS configuration guides and command references.
Step 6 If you have not already done so, configure the network module or WAN interface card that you plan to use for IP traffic. For instructions, see your router's installation and configuration guide or the configuration note for the network module or WAN interface card.
Step 7 To configure another interface, enter the exit command to return to the Router(config)# prompt.
Step 8 To configure the router for voice traffic, and to configure voice interfaces, refer to the detailed instructions in the Voice over IP Quick Start Guide or the Voice over IP Software Configuration Guide.
To comply with national regulatory requirements, you may need to set call progress tone detection to match your local PSTN. See the "Call Progress Tone Settings" section for further information.
If you are using a VIC-2/EM in Australia, you may need to adjust the answer wink width. The command to do this is:
Router(config-voice-port)# timing answer-winkwidth value
where value is in milliseconds, and should be between 110 and 130. The default is 210.
Step 9 When you finish configuring interfaces, exit configuration mode and return to the enable prompt by pressing Ctrl-Z. To see the current operating configuration, including any changes you just made, enter the show running-config command:
Router# show running-config
To see the configuration currently stored in NVRAM, enter the show startup-config command at the enable prompt:
Router# show startup-config
Step 10 The results of the show running-config and show startup-config commands differ from each other if you have made changes to the configuration, but have not yet written them to NVRAM. To write your changes to NVRAM, making them permanent, enter the copy running-config startup-config command at the enable prompt:
Router# copy running-config startup-config Building configuration. . . [OK] Router#
The router is now configured to boot in the new configuration.
