Warning

Before working on a system that has a standby/off switch, turn off the power by pressing the power
switch to standby and unplug the power cord.

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.

The IDSL connection is regarded as a source of voltage that should be inaccessible to user contact.
Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or
connection hardware. Any hardwired connection (other than by a nonremovable,
connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.

Statement 23

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. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Statement 1040

Statement 150

Statement 43

Statement 1021

Warning

If the symbol of suitability with an overlaid cross ( ) appears above a port, you must not connect the
port to a public network that follows the European Union standards. Connecting the port to this type
of public network can cause severe personal injury or can damage the unit.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different
electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic
components are improperly handled, and it can damage equipment and impair electrical circuitry.
Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry
atmosphere.

Step 1 Always use the following ESD-prevention procedures when removing and replacing components:

Connect the chassis to earth ground with a wire that you provide.

Step 2 Wear an ESD-preventive wrist strap that you provide, 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.
Always follow the guidelines in the preceding section, “Safety.”

Step 3 Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable

attached.

Unpacking the Router

If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the
cable.

Note This device is intended for use in residential and commercial environments only.

Caution Periodically check the resistance value of the antistatic strap, which should be between 1 and 10

megohms (Mohms).

Preventing Router Damage

Use the following guidelines when connecting devices to your router:

• Connect the color-coded cables supplied by Cisco to the color-coded ports on the back panel.

• If the symbol of suitability ( ) appears above a port, you can connect the port directly to a public

network that follows the European Union standards.

Warning

If the symbol of suitability with an overlaid cross appears above a port, you must not connect the

port to a public network that follows the European Union standards. Connecting the port to this type
of public network can cause severe personal injury or can damage the unit.

Unpacking the Router

Your router package should include the following items:

• Ethernet cable (yellow)

• IDSL cable (red)

• RJ-45 to RJ-11 adapter cable (for use with red IDSL cable)

• Desktop power supply

• Power cord (black)

• Console cable (light blue)

• DB-9 to RJ-45 adapter (for use with light blue console cable)

Connecting an Ethernet Device

This section describes how to connect a hub, server, PC, or workstation with a 10- or 10/100-Mbps
network interface card (NIC).

Before connecting an Ethernet device, you need to know the following:

• Cisco provides one yellow cable to connect an Ethernet device. If you want to connect more than

one device, you must provide additional straight-through cables. See the Cisco 800 Series Routers
Hardware Installation Guide for straight-through cable specifications.

• The TO HUB/TO PC button corresponds to the Ethernet port on Cisco 802 IDSL routers and to

Ethernet port 1 on Cisco 804 IDSL routers.

Caution Always connect the yellow cable or Ethernet cable to the yellow ports on the router. Do not connect the

cable to an IDSL port or to a Network Termination 1 (NT1) device. Accidently connecting the cable to
the wrong port can damage your router.

Configuring the IDSL Router

You can configure your Cisco IDSL router using the Cisco IOS command-line interface or the Cisco 800
Fast Step application. For information about using Cisco 800 Fast Step, refer to the Cisco 800 DSL
Connection Kit document in the product accessory kit or on Cisco Connection Online (CCO).

The following procedures are examples of how to configure the Cisco IDSL router using Cisco IOS
commands. For more information about Cisco IOS commands, refer to the Cisco IOS documentation set
on Cisco.com.

Basic IDSL Configuration

The following is an example of a typical IDSL configuration.

Step 1 In global configuration mode, specify a name for the router. For example:

router(config)# hostname 802

Step 2 Specify a username and password. The username is the destination router’s hostname. The password

must be the same for both the host and destination routers. For example:

router(config)# username isp password cisco

Configuring the IDSL Router

Step 3 Set the switch type. For example:

router(config)# isdn switch-type basic-5ess

Step 4 Set the BRI interface to use the ISDN physical connection as a leased-line service. The following

example sets the line speed at 128 kbps:

router(config)# isdn leased-line bri0 128

Step 5 Configure DHCP relay pool name. For example:

router(config)# ip dhcp pool DHCPpoolLAN_0

Step 6 Set the DHCP pool of addresses. For example:

router(dhcp-config)# network 192.168.1.0 255.255.255.0

Step 7 Set the IP addresses of the DNS servers. For example:

router(dhcp-config)# dns-server 172.29.20.41 172.29.20.51

Step 8 Set the NetBIOS servers. For example:

router(dhcp-config)# netbios-name-server 172.29.20.41 172.29.20.51

Step 9 Set the Ethernet 0 IP address as the default gateway. For example:

router(dhcp-config)# default-router 192.168.1.1

Step 10 Exit to global configuration mode.

router(dhcp-config)# exit
router(config)#

78-10368-03

Step 11 Define the IP addresses of the DNS servers. For example:

router(config)# ip name-server 172.29.20.41
router(config)# ip name-server 172.29.20.51

Example of Basic Configuration Output

Step 12 Change to interface command mode. For example:

router(config)# interface ethernet0
router(config-if)#

Step 13 Enter the IP address and subnet mask for the LAN. For example:

router(config-if)# ip address 192.168.1.1 255.255.255.0

Step 14 Enable Network Address Translation (NAT) on your LAN. The inside network address is not directly

routed to the Internet but is subject to translation to a routable address outside the LAN.

router(config-if)# ip nat inside

Step 15 Set the BRI interface IP address. In the following example, IP addresses are dynamically assigned:

router(config-if)# interface bri0
router(config-if)# ip address negotiated

Step 16 Enable PPP.

router(config-if)# encapsulation ppp

Step 17 Configure CHAP authentication.

router(config-if)# ppp authentication chap

Step 18 Configure a valid Internet address to which the inside network address will be translated.

router(config-if)# ip nat outside

Step 19 Define the router hostname and password to authenticate. For example:

router(config-if)# ppp chap hostname 802
router(config-if)# ppp chap password cisco

Step 20 Exit to global configuration mode. Add default route and interface. For example:

router(config-if)# exit
router(config)# ip route 0.0.0.0 0.0.0.0 bri0

Step 21 End configuration mode.

router(config)# end
router#

Step 22 In user mode, set global NAT commands. In the following example, all inside network addresses

assigned to interface BRI0 are configured for translation, and the access list that contains the inside
network addresses is defined.

router# ip nat inside source list 1 interface bri0 overload
router# access-list 1 permit 192.168.1.0 0.0.0.255

Step 23 Save your configuration.

IDSL Configuration with Frame Relay

IDSL Configuration with Frame Relay

The following procedure is an example of how to configure IDSL with Frame Relay.

Step 1 In global configuration mode, specify a name for the router. For example:

router(config)# hostname 802

Step 2 Specify a username and password. The username is the destination router’s hostname. The password

must be the same for both the host and destination routers. For example:

router(config)# username isp password cisco

Step 3 Set the switch type. For example:

router(config)# isdn switch-type basic-5ess

Step 4 Set the BRI interfaces to use the ISDN physical connection as a leased-line service. The following

example sets the line speed at 144 kbps:

router(config)# isdn leased-line bri0 144
router(config)# isdn leased-line bri0.1 144

Step 5 Change to interface command mode. For example:

router(config)# interface ethernet0

Step 6 Enter an IP address. For example:

router(config-if)# ip address 192.168.2.1 255.255.255.0

Step 7 Enable Network Address Translation (NAT) on your LAN. The inside network address is not directly

routed to the Internet but is subject to translation to a routable address outside the LAN.

router(config-if)# ip nat inside

Step 8 Change to BRI interface.

router(config-if)# interface bri0

Step 9 Configure interface with no IP address.

router(config-if)# no ip address

Step 10 Configure NAT so that the inside network address will be translated to a valid Internet address.

router(config-if)# ip nat outside

Step 11 Specify the encapsulation type. In the following example, IETF is used to connect to non-Cisco routers.

router(config-if)# encapsulation frame-relay ietf

Step 12 Specify the Local Management Interface (LMI) type used by the Frame Relay switch. For example:

router(config-if)# frame-relay lmi-type ansi

14

Step 13 Specify the subinterface point-to-point. For example:

router(config-if)# interface bri0:1 point-to-point

Step 14 Specify the IP address on the subinterface. For example:

Troubleshooting Using Debug Commands

In general, Cisco recommends that you use these commands with the direction of your technical support
representative. Using the debug commands can disrupt operation of the router when your internetwork
is experiencing a high-load condition.

When you finish using a debug command, remember to disable it with the specific no debug command
or with the no debug all command.

To minimize the impact of using debug commands, use the following procedure:

Step 1 Enter the following command from global configuration mode:

router (config)# no logging console

This command disables all logging to the terminal or PC that you are troubleshooting the software from.
(To reenable logging, enter the global configuration mode logging console enable command.)

Step 2 To use the debug commands, do the following:

a. Access any router port remotely using Telnet, and enter the following command while in user EXEC

mode:

router> enable

b. To show debug command output and error messages, enter the following command:

router> terminal monitor

c. To disable logging on the virtual terminal, enter the following command:

router> terminal no monitor

d. Enter the desired debug commands.

Performing this procedure minimizes the load created because the console port no longer needs to
generate character-by-character processor interrupts.

The following table describes debug commands, problems your router might be experiencing, and
solutions to the problems. An output example from each command appears after the table.

Cisco Product Security Overview

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you can perform these tasks:

• Report security vulnerabilities in Cisco products.

• Obtain assistance with security incidents that involve Cisco products.

• Register to receive security information from Cisco.

A current list of security advisories and notices for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

If you prefer to see advisories and notices as they are updated in real time, you can access a Product
Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:

• Emergencies—[e-mail]

• Nonemergencies— [e-mail]

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive

information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one that has the most recent creation date in this public key server list:

http://pgp.mit.edu:11371/pks/lookup?search=psirt%40cisco.com&op=index&exact=on

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

78-10368-03

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.

Installing and Configuring Cisco 802 IDSL and Cisco 804 IDSL Routers

21

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects
of your business operation are negatively affected by inadequate performance of Cisco
products. You and Cisco will commit full-time resources during normal business hours to
resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business
operations remain functional. You and Cisco will commit resources during normal business
hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities,
installation, or configuration. There is little or no effect on your business operations.
