This document describes the hardware installation and software configuration steps necessary to install your Cisco modular access router with its complement of WAN interface cards WICs and voice interface cards VICs.

Additional documentation can be found on Cisco. The serial number label for Cisco router is located on the rear of the chassis, in the lower right-hand corner. Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable.

The following guidelines are provided to ensure your safety. The rack-mounting brackets supplied with the router can be attached to a or inch rack. Figure 1 shows the bracket mounting points that attach to the rack. To install the router in a inch or a inch standard rack, follow the instructions described in these procedures:. The bracket orientation and the screws you use depend on whether you are attaching the brackets for a inch or a inch rack.

Use two of the supplied screws to attach each bracket, according to the following guidelines:. Figure 2 shows how to attach brackets to the two sides of the router with the front panel forward. After the brackets are attached to the router, use the four supplied number Phillips machine screws to securely attach the brackets to the rack, as shown in Figure 3.

Cisco recommends attaching the cable guide to prevent the cables from obscuring the front panel of the router and the other devices installed in the rack.

If the router is in a inch or inch rack, use the supplied black screw, as shown in Figure 4 , to attach the cable guide to the left or right bracket. To see translated versions of these warnings, refer to the Regulatory Compliance and Safety Information for the Cisco Routers document that came with the router.

Warning Only trained and qualified personnel should be allowed to install or replace this equipment. 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 Before opening the chassis, disconnect the telephone-network cables from the card to avoid contact with the telephone-network voltages. Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Step 1 Make sure the router is turned off and is disconnected from AC power. You should be able to loosen the screws using your fingers; however, if the screws are very tight, you may need to use a Phillips screwdriver. Step 3 Remove the metal plate that covers the card slot.

Step 4 Hold the card by the edges on either side of the card front panel, and line up the card edges with the guides inside the card slot, as shown in Figure 6. Step 5 Insert the card in the slot, and gently push it into the router until the front panel of the card is flush with the router. Note Slots 2 and 3 accept VICs only. These slots have a small metal tab on the right side that interferes with a similar tab on WICs, preventing the insertion of WICs by mistake.

Step 6 Tighten the screws that are on the card. When the router is connected to a PC and you are running the command-line interface, as described in the "Connect a PC to the Router Console Port" section, you can enter the show voice port command to identify the port numbers of voice interfaces installed in your router:.

As an example of voice port numbering, if you install VICs in both slot 1 and slot 2 of the router, the ports in each of these slots would be numbered as follows:. Figure 7 shows the Cisco router front panel and slot numbering. You must provide the following items for this connection:. To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco Routers document that came with the router.

Step 2 Connect the other end of the Ethernet cable to a network port on the hub or switch. Warning The power supply is designed to work with TN power systems.

Warning This product relies on the building's installation for short-circuit overcurrent protection. Warning This equipment needs to be grounded. Use a green-and-yellow 14 AWG ground wire to connect the host to earth ground during normal use. Warning When installing the unit, always make the ground connection first and disconnect it last. Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor.

Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Step 1 Connect the separate power cord to the power socket on the rear panel, as shown in Figure 9. Step 2 Connect the other end of the separate power cord to a power outlet. Step 3 Turn the power switch to on. Step 4 Verify that you have correctly installed the router by checking the following LEDs:. Connect a PC to the router's console port and establish a console session to view startup messages and verify voice card installation.

Follow these steps to connect the router to a terminal or PC:. Step 1 Connect the light blue console cable to the blue console port on the router, as shown in Figure Step 2 Use the console adapter to connect the other end of the cable to the terminal or PC.

If your terminal or PC has a console port that does not fit the adapter included with the router, you must provide the correct adapter for that port. Set the configurations to baud, 8 data bits, 1 stop bit, no flow control, and no parity. You can use the CLI if the following messages appear at the end of the startup sequence:. If these messages do not appear, SDM and a default configuration file were installed on the router at the factory.

Note Be sure to save your configuration changes occasionally so that they are not lost during resets, power cycles, or power outages. Step 1 To proceed with manual configuration using the CLI, enter no when the power-up messages end. Step 2 Press Return to terminate autoinstall and continue with manual configuration. Step 6 Verify the initial configuration. See the "Verifying the Initial Configuration" section for verification procedures.

To verify that the new interfaces are operating correctly, perform the following tests:. As an example of voice port numbering, if you installed VICs in both slot 1 and slot 2 of the router, the ports in each of these slots would be numbered as follows:. When you have completed and verified the initial configuration, your Cisco router is ready to configure for specific functions. International users must set the values of certain voice-port commands, such as cptone , that are specific to their country.

The rest of this guide explains how to configure your router for VoIP traffic. You must save the new configuration to nonvolatile RAM NVRAM periodically during the configuration process and also when you finish configuring the router. Cisco IOS software uses two configuration files— startup-config and running-config.

The startup-config file is a backup file that has all the information you specified about the router interfaces. The startup-config file is used by the router on the next restart. The running-config file has the current operating configuration with the changes you have just made.

You can make any changes to the running-config file; however, these changes will be lost when the router powers down. To make these changes permanent, copy the running-config file to the startup-config file stored in NVRAM.

Step 1 Exit configuration mode, and return to the enable prompt by pressing Ctrl-Z or entering the end global configuration command. Step 3 To see the operating configuration, including any changes you have just made, enter the following command:. To configure the Fast Ethernet interface, follow these steps, beginning in global configuration mode:.

Use a dial plan to map the destination telephone numbers with the voice ports on the router. Area codes are assigned geographically, office codes are assigned to specific switches, and station codes identify specific ports on each switch. Internationally, each country is assigned a one- to three-digit country code; the country's dialing plan follows the country code.

In corporate environments, VoIP can be configured to recognize extension numbers and expand them into their full E. Before you configure these two commands, map individual telephone extensions with their full E.

You can do this easily by creating a number expansion table. For Cisco voice implementations, three types of dial peers are used to match a dialed number to either a local telephony port or a remote IP address:. The key commands that you need to configure are the port and destination-pattern commands, as in the following example:. The destination-pattern command defines the telephone number associated with the POTS dial peer.

The port command associates the POTS dial peer with a specific logical dial interface, normally the voice port connecting your router to the local POTS network.

The key commands that you need to configure are the destination-pattern and session target commands, as in the following example:. The destination-pattern command defines the telephone number associated with the VoIP dial peer. The key commands you need to configure are the destination-pattern and session target commands, as in the following example:. The destination-pattern command defines the telephone number associated with the VoFR dial peer.

Use the dial-peer voice command to define dial peers and to change to dial peer configuration mode. Office PBXs are configured so that a user can dial a local call within the same PBX by dialing the extension only—for instance, the four-digit extension , or the five-digit extension —rather than dialing the full telephone number, 1 You can provide the same shortcut on a VoIP network by using the number-expansion num-exp command.

This command tells the router to expand a particular sequence of dialed numbers into a complete telephone number destination pattern as shown in Table 1. To expand any dialed sequence of four digits represented by four periods by prefixing to it.

To expand a five-digit extension beginning with the numeral 5 by prefixing to it. You can use a period. You can use the show num-exp command to verify the number expansion information.

After you have configured dial peers and assigned destination patterns to them, you can use the show dialplan number command to see how a telephone number maps to a dial peer.

Note You must still configure each telephone number in full on a local dial peer so that the router can find the voice port to which it belongs. The router supports one to four Cisco VICs. Each VIC provides two ports. You need one VIC port for each voice connection. Ports on this VIC are gray. This is the interface a standard telephone provides.

Ports on this VIC are pink. Ports on this VIC are brown. It can also be configured to provide a network termination NT interface with phantom power. You should install and cable the VICs before you perform the software configuration tasks that follow.

This section explains how to configure ports on FXS VICs that connect directly to a standard telephone, a fax machine, or a similar device.

Figure 12 shows a basic voice network. A small business uses a Cisco router named West to provide telephone and fax connections among employees in its office.

Note You can name your router by using the global configuration hostname command. For information about port numbering, see the "Voice Port Verification" section. Note I f your router is configured with four 2-port VICs, you can connect a total of eight telephones and fax machines to it. To route a received voice call to the right destination, the router needs to know which telephone number belongs to each voice port. In other words, the router needs to know the information in Table 2.

To hold this information, Cisco IOS software uses objects called dial peer s. A telephone number, a voice port, and other call parameters are tied together by associating them all with the same dial peer. Configuring dial peers is similar to configuring static IP routes—you are telling the router what path to follow to route the call. All voice technologies use dial peers to define the characteristics associated with a call leg.

A call leg is a segment of a call path, for instance, between a telephone and a router, a router and a network, a router and a PBX, or a router and the PSTN. Each call leg corresponds to a dial peer. Dial peers are identified by numbers, but they are usually referred to as tags to avoid confusion with telephone numbers. Dial-peer tags are arbitrary integers that can range from 1 to - 1 Within the allowed range, you can choose any dial-peer tag that is convenient or that makes sense to you.

Dial peers on the same router must have unique tags, but you can reuse the tags on other routers. Table 3 assigns a dial-peer tag to each telephone number and its associated voice port on the West router. This type of dial peer is called a POTS dial peer or a local dial peer. The term POTS plain old telephone service means that the dial peer associates a physical voice port with a local telephone device.

You should construct a table similar to Table 3 for your own routers, assigning your own telephone numbers and dial-peer tags. Note The telephone numbers used in this guide are only examples and are invalid for public use in the United States. When you configure your network, be sure to substitute your own telephone numbers. To configure the router with the dial-peer information in Table 3 , enter the following global configuration commands:.

These commands are summarized in Figure The dial-peer command always takes the argument voice. The number following it is the dial-peer tag, and pots is the type of dial peer. Cisco IOS software refers to a telephone number as a destination pattern because it is the destination for an incoming or outgoing call. Enter these numbers with the destination-pattern command. Notice that the commands in the examples puts the prefix 1 used in the United States to indicate a long-distance number and an area code in front of the remaining numbers to complete the destination pattern.

It accepts any string of permitted characters as a valid number. The business that owns the West router also has a branch office, called East. Figure 14 shows the East office network, and Table 4 lists the phone numbers, voice ports, and dial-peer tags for this office. Enter the following commands to configure the local ports on the East router with the dial-peer information in Table 4 :. If you configured POTS dial peers on your router by following these examples, you can place calls between telephones connected to the same router.

You can also use the show dial-peer voice command to verify that the data that you configured is correct. Note If the voice port is off line, use the interface configuration no shutdown command at the config-voice-port prompt to enable it. To enable the West and East offices to send voice traffic to each other over the same IP network they use for data traffic, use a WIC on each router to provide a connection to the IP network, as shown in Figure Look at the connection between the West router and the IP network.

This connection does not include a voice port or an attached telephone—it leads from a WAN interface to a remote destination somewhere on the IP network. IP routers can locate IP addresses on the network, but they cannot locate telephone numbers.

To route an outgoing voice call over this connection, the West router must associate a telephone number in the East office with the IP address of the East router.

Table 5 assigns a dial-peer tag to each telephone number and its associated IP address on the West router. This type of dial peer is called a remote dial peer or VoIP dial peer.

Remember, the dial-peer tags are arbitrary. But it is much easier to use periods as wildcards, as shown in Table 6. Construct a table similar to Table 6 for your own routers, assigning your own telephone numbers, IP addresses, and dial-peer tags. Note The IP addresses shown in this guide are meant only as examples. When you configure your network, be sure to use your own IP addresses. Enter the following information on the West router to create the dial-peer configuration given in Table 6 :.

Cisco IOS software describes the remote network as the session target. This command is followed by the IP address of the remote router. The prefix ipv4 means IP version 4.

Configure a dial peer on each router for each telephone number on every other router connected to it.

You can simplify this process by configuring number expansion for East router telephone numbers on the West router:. Now users can dial a five-digit extension beginning with 5 from a telephone on the West router to reach a telephone on the East router. Table 7 shows how to configure the East router to send calls to the West router.

Enter the following information on the East router to create the dial-peer configuration given in Table 7 :. If the path between the endpoints of a voice call travels through intermediate routers, configure those routers for VoIP traffic, as described in the "Configuring FXS Interfaces" section.

If you configured VoIP dial peers on your router by following these examples, you can place calls from that router to telephones on the remote routers using just the extension if you configured number expansion. If you have trouble placing calls, ping the remote router to make sure you have IP connectivity, or use the show dial-peer voice command to verify that the data you configured is correct.

Note See the "Configuring Quality of Service" section if you need to improve the quality of voice connections. Figure 19 shows a typical FXO gateway attached to the West router. To create a POTS dial peer for an FXS interface as explained earlier, you enter the complete telephone number of the attached telephone as the destination pattern for incoming calls. For instance, to dial 9 to reach an outside line that is, the analog PSTN , enter the following commands:.

The PSTN then provides a dial tone. Any digits you enter on the telephone thereafter are interpreted on the PSTN. Dial peer matches calls beginning with the digit 9 and handles PSTN calls originating from the West router. Dial peer matches calls beginning with the digit 7 and handles calls to the PSTN originating from the East router. If you have trouble placing calls, use the show voice port command to make sure that the VIC is installed correctly.

Use the show dial-peer voice command to make sure that the data you configured is correct, and test the PSTN by connecting a handset directly to the PSTN outlet and placing a call. If you have more than a few voice users at each location, the cost of voice ports and routers and the effort needed to configure dial peers for all the combinations of origins and destinations increases rapidly.

Figure 20 shows a company with two offices, West and East. Each office has a PBX to operate its internal telephone network, and the IP network carries voice traffic between the offices. The values for your configuration depend on your PBX and are available from your telecommunications department or the PBX manufacturer.

In this example, West users can dial 5 and a four-digit extension to reach telephones in the East office. East users can dial 5 and a four-digit extension to reach telephones in the West office. This port is associated with a POTS dial peer for incoming calls. But you no longer need to associate every telephone number with its own port. Instead, you can configure a local dial peer as if all the West telephones represented by a wildcard destination pattern are connected directly to this port, as shown in the following commands:.
