Requirements
This section describes the requirements and standards supported for the WIC-1SHDSL card.
Software Requirements
The WIC-1SHDSL card requires Cisco IOS Release 12.2(4)XL or later.
Memory Requirements
The memory requirements for running the full-featured Cisco 1700 router encryption images with the G.SHDSL WIC are as follows:
•16 MB of Flash memory
•64 MB of dynamic RAM (DRAM)
Caveats
The following are caveats concerning the use of a WIC-1SHDSL card.
•If the WIC-1SHDSL card is used with an IOS image that does not support it, an error message appears, indicating an unrecognized WIC. This does not damage the router or the WIC-1SHDSL card. The error message is "00:00:05: %PQUICC-1-UNKNOWN_WIC: PQUICC(0), WIC card has an unknown ID of 0xFF."
•ConfigMaker does not recognize the WIC-1SHDSL card.
•The WIC-1SHDSL card does not support dual latency. When the DSL link is intended to support both voice and data traffic simultaneously, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.
•The WIC-1SHDSL card does not support "dying gasp" in ANSI T1.413 Issue 2.
•The WIC-1SHDSL card does not support ABR CoS.
•On Cisco 1700 series routers, the WIC should be inserted only in slot 0 or slot 1.

Power Supply Warnings
The following warnings apply when you are installing a card or working with the power supply:
Warning Read the installation instructions before you connect the system to its power source.
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning Warning: Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
Electrical Warnings
The following warnings apply when you are working with electricity:
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 RJ-45 connectors. Use caution when connecting cables.
Warning No operator-serviceable parts inside. Refer servicing to qualified personnel.
Follow these guidelines when working on equipment powered by electricity:
•Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power off.
•Before working on the router, turn off power to the router and unplug the power cord.
•Disconnect all power before doing the following:
–Installing or removing a router chassis
–Working near power supplies
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.
If an electrical accident occurs, proceed as follows:
•Use caution; do not become a victim yourself.
•Turn off power to the router.
•If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.
•Determine if the victim needs rescue breathing or external cardiac compressions; then take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur when 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 guard against ESD damage and shocks, the wrist strap and cord must be used properly. 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 (Mohms).
Connecting a G.SHDSL Card to the Network
Use a straight-through RJ-11 cable for this connection. The port on this interface card is color-coded lavender.
If you are connecting a DSL card to an RJ-11 wall jack that has the DSL pair wired for pins 2 and 5, you must use an RJ-11 crossover cable (lavender with blue stripe). The RJ-11 crossover cable is orderable separately as a spare.
Complete the following steps to connect a 1-port G.SHDSL card to the network:
Step 1 Confirm that the router is turned off.
Step 2 Connect one end of the cable to the G.SHDSL port on the card.
Step 3 Connect the other end to the wall jack (RJ-11) at your site, as shown in Figure 2.
Figure 2 Connecting a G.SHDSL WIC to the Wall Jack
Step 4 Turn on power to the router.
Step 5 To connect the card to the network, you must configure the card in the router to the no shutdown state. Enter the no shut command in the router configuration. Check that the CD LED goes on, indicating that the card is connected to the network.
Configuration Modes
Whenever you install a new card, or if you want to configure an existing card, you must configure the interface. If you replace a card that was already configured, the router recognizes it and brings up the interface by using the existing configuration.
Before you configure an interface, have the following information available:
•Protocols you plan to route on the new interface
•IP addresses, subnet masks, network numbers, zones, or other information related to the routing protocol
Obtain this information from your system administrator or network plan before you begin configuring the router.
You can configure the new interface and other router parameters by using any of the following methods:
•Command-Line Configuration (manual configuration)—recommended if you are familiar with IOS commands. Enter the commands and values at the prompt.
•System Configuration Dialog (Setup facility)—recommended if you are not familiar with IOS commands. You are prompted for each value.
•AutoInstall (automatic installation)—recommended if another router running IOS software is installed on the network. This configuration method must be coordinated in advance by someone with experience using IOS software, such as the network administrator.
These procedures are explained in the following sections. To change the settings shown in the examples and to obtain further information, refer to the IOS configuration guides and command references. If you have questions or need help, see the "Obtaining Technical Assistance" section in this document.
Command-Line Configuration
You can configure the card by entering IOS commands on the command line. This method provides the greatest power and flexibility. For further information about these commands, refer to the IOS configuration guides and command references. You can display help by entering a question mark (?) at the prompt.
Before you begin, disconnect all WAN cables from the router to prevent it from running the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and if 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.
To configure the card by using the command-line interface (CLI), follow this procedure:
Step 1 Connect a console or a PC running terminal emulation software, such as HyperTerminal, to the router. If you need instructions for connecting to the console port of the router, refer to the installation chapter of your router installation and configuration guide.
Step 2 Power on the router. If the startup configuration is valid, the EXEC prompt (Router>) appears. If the startup configuration is not valid, the router attempts to run Auto Install, and the following prompt appears:
Would you like to enter the initial dialog? [yes]:
Step 3 Enter no and press Enter to display the EXEC prompt.
Step 4 Enter enable and the password (if any) to enter enable mode. The prompt changes to the privileged mode prompt (Router#). Configuration changes can be made only in enable mode.
Step 5 Enter config terminal to enter configuration mode:
The router enters global configuration mode, shown by the Router(config)# prompt.
If you want to change the router configuration, you can configure global parameters, passwords, network management, and routing protocols. For complete information about global configuration commands, refer to the IOS configuration guides and command references.
Step 6 Select the Ethernet interface to configure. The following uses the Cisco WIC-1ENET interface as an example:
Router(config)#interface Ethernet 0
The prompt changes again to show that you are in interface configuration mode.
Step 7 Configure the routing protocols on the interface. (You must have previously enabled these protocols as part of global configuration.) In this example, IP and IPX are being configured:
Router(config-if)#ip address ipaddress subnetmask
Router(config-if)#ipx network networknumber
Step 8 Enter no shutdown to enable the port:
Router(config-if)#no shutdown
Step 9 Enter exit to return to the Router(config)# prompt.
Step 10 Exit configuration mode, and return to privileged mode by pressing Ctrl-Z. To see the current running configuration, including any changes you made, enter the show running-config command:
Router#show running-config
Step 11 To store the running configuration in NVRAM, enter the copy running-config startup-config command while in privileged mode:
Router#copy running-config startup-config
Building configuration. . .
The router automatically copies the startup configuration in NVRAM to the running configuration and executes it whenever the router is powered on or the reload command is entered. To see the configuration stored in NVRAM, enter the show startup-config command:
Router#show startup-config
System Configuration Dialog
You can configure the router by using the system configuration dialog (also called the Setup facility). The system configuration dialog prompts you for each response.
This section shows a sample configuration using the system configuration dialog. You should enter values appropriate for your router and network. To change the settings shown in the examples and to obtain further information, refer to the IOS configuration guides and command references.
Many prompts in the system configuration dialog include default answers, shown in square brackets following the question. Enter your response, or press Return to accept the default answer.
You can request help at any time by entering a question mark (?) at the system configuration dialog prompt.
Before you begin, disconnect all WAN cables from the router to prevent it from running the AutoInstall process. 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 TCP/IP host.
Follow these steps to configure the router by using the system configuration dialog:
Step 1 Power down the router, and install the card.
Step 2 Connect a console to the router. If you need instructions for connecting a console, refer to the installation chapter of your router installation and configuration guide.
Step 3 Power on the router.
If the router does not have a valid startup configuration file, it tries to run AutoInstall. The following prompt appears:
Would you like to enter the initial dialog? [yes]:
Step 4 Enter no, and press Enter to display the EXEC prompt (Router>).
If the startup configuration is valid, the EXEC prompt (Router>) appears.
Step 5 Enter enable to enter privileged mode. The enable prompt (Router#) appears. Enter enter setup mode and display the system configuration dialog as follows:
Step 6 Enter Setup mode by entering the following command:
Step 7 Follow the prompts and change the parameters, or accept the defaults to configure global parameters, such as passwords, network management, and routing protocols. Refer to the procedures in the IOS configuration guides and command references.
The following is an example of the process.
a. Enter yes to start setup mode.
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
b. Respond to the prompt as follows:
Would you like to enter basic management setup? [yes/no]: no
First, would you like to see the current interface summary? [yes]: no
c. Enter the host name of the router as follows:
Configuring global parameters:
Enter host name [Router]: hostname
d. Enter the enable secret password as follows:
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: password
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
e. Enter the enable password as follows:
Enter enable password: password
f. Enter the virtual terminal password as follows:
The virtual terminal password is used to protect
access to the router over a network interface.
Enter virtual terminal password: password
g. Respond to the prompts as follows:
Configure SNMP Network Management? [yes]: no
Configure IGRP routing? [yes]: yes
Your IGRP autonomous system number [1]: 1
Configure bridging? [no]: no
h. Enter the IP address and subnet mask as follows:
Configuring interface parameters:
Do you want to configure Ethernet0 interface? [yes]: yes
Configure IP on this interface? [yes]: yes
IP address for this interface: ipaddress
Subnet mask for this interface [255.0.0.0] : netmask
Class X network is x.x.x.x, x subnet bits; mask is /x
Do you want to configure FastEthernet0 interface? [yes]: no
The following configuration command script was created:
enable secret 5 $1$ANpR$LYOj7mFpk1TE7SSAXDgVA/
ip address x.x.x.x x.x.x.x
After the configuration you entered appears, you are asked if you want to use it.
Step 8 Enter yes to save the startup configuration:
Use this configuration? [yes/no]: yes
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.
Press RETURN to get started!
The configuration is saved.
Enter no if you do not want to save the configuration. The information you entered is discarded, and you can reenter the configuration parameters.
AutoInstall
The AutoInstall process is designed to configure the router automatically after it connects to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be configured to provide the configuration files. The TCP/IP host can reside anywhere on the network if the following two conditions exist:
•The host is on the remote side of the router's synchronous serial connection to the WAN.
•User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host is enabled.
This functionality is coordinated by your system administrator at the TCP/IP host site. You should not try to use AutoInstall unless the required files are installed on the TCP/IP host.
Follow this procedure to prepare your router for the AutoInstall process:
Step 1 Connect the router to the WAN.
Step 2 Turn on power to the router. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process begins.
Step 3 If AutoInstall succeeds, write the configuration data to NVRAM. To do this, enter the copy running-config startup-config command at the Router# prompt:
Router# copy running-config startup-config
Building configuration. . .
This saves the configuration settings that the AutoInstall process created. If you do not do this, your configuration will be lost the next time you boot the router.

Configuring ILMI on the DSLAM Connected to the WIC-1SHDSL Card
The Interim Local Management Interface (ILMI) protocol allows DSLAMs to be used for ATM address registration across an ATM User-Network Interface (UNI). If ILMI is configured on the WIC-1SHDSL card, the ATM PVC must be configured on the DSLAM. All switch-terminating connections use interface 0/0 to connect to the switch CPU.
For information about configuring the DSLAM, refer to the Configuration Guide for Cisco DSLAMs with NI-2.
Verifying ATM Configuration
Use the following commands to verify your configuration:
•Use show running-config to verify the current configuration and to view the status for all controllers.
•Use show controllers atm slot/port to view ATM controller statistics.
•Use show atm vc to verify the PVC status. Make sure that active PVCs are up.
•Use debug atm events to help identify ATM-related events as they are generated. Use debug atm errors to determine which interfaces are having trouble.
•Use show ip route to verify an entry for the ATM interface you configured.
•Use show interface atm slot/port to view the status of ATM interface. Make sure ATM slot/port and line protocol is up, as shown in the following example:

•Use show dsl interface atm slot/port to view the status of WIC-1SHDSL card. If the line is down, the following statement appears: Line is not active. Some of the values may not be accurate. You can also verify whether the equipment type and operating mode configuration are correct for your application.

Configuring Quality of Service Parameters
This section describes QoS parameters that can be configured for Cisco 1700 series routers, using the WIC-1SHDSL card. The following are included:
•Low Latency Queuing (Priority Queuing with Class-Based Weighted Fair Queuing)
•DiffServ
•Committed Access Rate
•Multilink PPP over ATM with Link Fragmentation and Interleaving
•Weighted Random Early Detection
•ATM per-VC Queuing and VC Bundling
•ATM Cell Loss Priority Bit Marking
•Compressed RTP
•Tunable Transmission Ring
•MLP Bundling
Low Latency Queuing (Priority Queuing with Class-Based Weighted Fair Queuing)
Low latency queuing (LLQ) allows strict priority queuing (PQ) to class-based weighted fair queuing (CBWFQ). This priority queuing allows delay-sensitive data such as voice packets to be de-queued and sent before other packet traffic, reducing jitter in voice conversations. To configure LLQ, enter the priority command under the CBWFQ configuration.
Configuration Example
The following example shows a Cisco 1751 router configured with LLQ:
ip address 10.0.0.10 255.255.255.252
interface ATM0/0.1 point-to-point
protocol ppp Virtual-Template1
interface Virtual-Template1
service-policy output 1751_DSL
ppp multilink fragment-delay 4
access-list 100 permit udp any any precedence critical
destination-pattern 3640200
session target ipv4:10.0.0.11
ip qos dscp cs4 signalling
DiffServ
DiffServ addresses the clear need for relatively simple and coarse methods of categorizing traffic into different classes and applying QoS parameters to those classes. DiffServ supports class-based marking.
Cisco Express Forwarding (CEF) mode is required for DiffServ support. To enable CEF, enter the ip cef command.
Configuration Example
The following example shows a Cisco 1751 router configured with DiffServ:
access-list 102 permit udp host 16.0.0.4 host 15.0.0.5
access-list 103 permit udp host 16.0.0.4 host 13.0.0.5
class-map match-all traffic-INTRA
class-map match-all traffic-INTER
class-map match-all traffic-dscp1
class-map match-any traffic-prec3
