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. Statement 150
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. Statement 43
Warning 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
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. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
Statement 1040
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. Statement 1031
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
Step 2
Step 3
Always use the following ESD-prevention procedures when removing and replacing components:
Connect the chassis to earth ground with a wire that you provide.
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, “
.”
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. Statement 1031

Step 4
Step 5
Step 6
Step 7
Step 8
In global configuration mode, specify a name for the router. For example: router(config)# hostname 802
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
Set the switch type. For example: router(config)# isdn switch-type basic-5ess
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
Configure DHCP relay pool name. For example: router(config)# ip dhcp pool DHCPpoolLAN_0
Set the DHCP pool of addresses. For example: router(dhcp-config)# network 192.168.1.0 255.255.255.0
Set the IP addresses of the DNS servers. For example: router(dhcp-config)# dns-server 172.29.20.41 172.29.20.51
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)#

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

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
Step 2
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.)
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 — [email protected]
•
Nonemergencies — [email protected]
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:

Obtaining Technical Assistance
Cisco Technical Support Website
The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day,
365 days a year, at this URL: http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password.
If you have a valid service contract but do not have a user ID or password, you can register at this URL: http://tools.cisco.com/RPF/register/register.do
Note
Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support
Website by clicking the Tools & Resources link under Documentation & Tools.
Choose Cisco Product
Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product
Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output.
Search results show an illustration of your product with the serial number label location highlighted.
Locate the serial number label on your product and record the information before placing a service call.
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: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447
For a complete list of Cisco TAC contacts, go to this URL: http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
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.

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.
