Restrictions for Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WIC

Memory Requirements

The Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WIC has the following memory requirements:

Cisco 2600 ip —8M Flash, 32M DRAMM

Cautions

Caution: Ensure that the RJ-11/CA11 telephone cable is disconnected from the modem WIC before installing or removing the modem WIC from the router. The phone jack can have DC potential (up to 56.5 VDC) and can have ring signal (up to 150 VAC) in the United States.

Caution: Ensure that the router is powered OFF before installing or removing the modem WIC from the router. The modem WICs do not support online insertion and removal (hot-swap).

Troubleshooting Commands

Other than some currently unsupported commands, the V.90 modem WIC supports all commands available for modem WICs as described in the Cisco IOS Wide Area Networking Configuration Guide. For troubleshooting and verification, use only the following commands:

clear modem [counters][slot/modem # | group group # | all]
debug modem
show modem slot/port

Most of the show modem commands do not display the WIC-1AM-V2 and WIC-2AM-V2 information. You may also see error messages, such as this example:

Router# show modem operational-status 0/0
Modem 0/0 doesn't exist.

Information About Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WIC

Features

Support for V.90/V.92/V.44.
A Cisco IOS command is provided to update the modem firmware. This command allows for upgrading in the field.
The country code is set by a modemcap.
The modem uses the Conexant AT Command Set.
More country codes are supported than on previous modems.

Applications

Remote Router Management and Out-of-Band Access

In this mode, the modem WIC is used as a dial-in modem for remote terminal access to the router's command-line interface (CLI) for configuration, troubleshooting, and monitoring. The modem WIC acts similar to a modem that is connected to the AUX port of a router, but the integrated nature of the modem WIC greatly decreases configuration time and deployment and sustaining costs. Typically, the 1-port modem WIC is used for this application. Connection speeds up to 33.6 kbps are possible.

Asynchronous Dial-on-Demand Routing and Dial-Backup

In this mode, the V.90 modem WIC transports network traffic. When ISDN service is not available and the traffic load does not justify a leased-line or Frame Relay connection, asynchronous dial-on-demand routing (DDR) is often the only choice for making a WAN connection. Even at sites that do have leased-line or Frame Relay connection, asynchronous DDR can increase bandwidth during sustained traffic load. In addition, when the primary leased-line or Frame Relay link is down during an outage, asynchronous dial-backup provides a secondary way to make the WAN connection. Both the 1-port and 2-port versions of the V.90 modem WIC can be used for this application.

For more information on Asynchronous Dial-on-Demand Routing and Dial-Backup, see the section Configuring Dial Backup for Serial Lines in the Cisco IOS Dial Technologies Configuration Guide.

Two ports on one modem WIC (or even three or more ports spanning multiple modem WIC cards) can be combined using Multilink PPP (MLP) to increase connection speeds in a scalar manner. Each connection is capable of V.90 speeds (up to 56 kbps) when connecting to a digital V.90 server modem.

For more information on MLP, see Multilink PPP for DDR—Basic Configuration and Verification.

Low-Density Analog RAS Access

In this application, the V.90 modem WIC enables the platform to provide the services of a typical small remote access server (RAS). One service allows remote users to dial in and gain access to resources on the LAN (or even across the WAN). The analog modems in the modem WIC allow dial-in connection speeds of up to 33.6 kbps, but MLP can bind multiple links together and increase the throughput.

Another service allows PCs (running Cisco DialOut Utility) on the LAN to use the modems for dial-out. Users can connect to other modems (bulletin boards, AOL, ISPs, and so on) or fax machines. The modem WIC allows dial-out connection speeds of up to 56 kbps when dialing a digital V.90 server modem or up to 33.6 kbps when dialing another analog modem. Fax calls connect at up to 14.4 kbps.

Typical RAS deployments with the V.90 modem WIC use the 2-port modem version. With enough slots, the V.90 modem WIC can be used to scale to up to 24 modems. There is no limit for lines in the MLP bundle with WICs and population of WICs on any Cisco 2600 series or Cisco 3600 series multiservices platforms.

peer default ip address pool poolname

Detailed Steps

Command or Action	Purpose
Step 1 enable Example: Router> enable	Enables privileged EXEC mode. • Enter your password if prompted.
Step 2 configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3 interface async number Example: Router(config)# interface async 2	Enters the interface configuration mode for the asynchronous serial interface. Enter the number of the interface you want to configure.
Step 4 ip unnumbered type number Example: Router(config-if)# ip unnumbered ethernet 0	Conserves IP addresses by configuring the asynchronous interface as unnumbered, and assigns the IP address of the interface type that you want to leverage.
Step 5 encapsulation ppp Example: Router(config-if)# encapsulation ppp	Sets the encapsulation protocol for Point-to-Point Protocol (PPP).
Step 6 dialer in-band [no-parity \| odd-parity] Example: Router(config-if)# dialer in-band no-parity	Specifies that dial-on-demand routing (DDR) is to be supported. This command specifies that chat scripts will be used on asynchronous interfaces. The parity keywords do not apply to asynchronous interfaces.
Step 7 dialer string number Example: Router(config-if)# dialer string 5551212	Enters the dialer string (telephone) number.
Step 8 dialer-group group-number Example: Router(config-if)# dialer-group 1	Controls access by configuring the interface to belong to a specific dialing group. The number to which the dialer access group belongs is defined with the dialer-list command. Acceptable values are within the range from 1 to 10.
Step 9 async mode interactive Example: Router(config-if)# async mode interactive	Configures interactive mode on the asynchronous interface.
Step 10 peer default ip address pool poolname Example: Router(config-if)# peer default ip address pool pool123	Assigns dial-in clients IP addresses from an address pool. To create an IP address pool, use the ip local pool global configuration command.

Configuration Examples

Configuring for Asynchronous Dial Backup: Example

In this example, the interface S2/0 is configured as a primary link. Configuring the route through the backup interface (the V.90 modem WIC in this case) is very important. 10.0.0.0 in the IP route indicates the network number of the remote end. Thus, all packets for the destination IP are routed through the backup link if the primary link goes down. The 180 in the route command indicates the cost of the route taken (It should be more than the cost of the primary route). This avoids the packets taking the backup link when the primary link is up.

The following example shows an asynchronous dial backup configuration:

interface Serial2/0
 ip address 70.1.1.2 255.255.255.0
 backup delay 15 15
 backup interface as33

Upgrade Modem Firmware Command Details

Syntax

upgrade modem firmware [all | slot slot | wic nm-slot/wic-slot] file source

Usage Guidelines

The source for the modem firmware file can be any of the following:

cns: Firmware filename
flash: Firmware filename
ftp: Firmware filename
null: Firmware filename
nvram: Firmware filename
rcp: Firmware filename
system: Firmware filename
tftp: Firmware filename
xmodem: Firmware filename
ymodem: Firmware filename

It is best to copy the modem firmware file to Flash: or Slot0: before trying to upgrade the modems. After selecting the source, specify the filename. For example,

tftp://192.168.100.26/mj-F48A-1824M-4M-Rev-2-bundle-image.bin

If a modem has a call up, the call will be torn down (the modems selected in the upgrade command, are hardware reset before starting the download). A series of dots are printed (one per second) until the selected modems have been upgraded. The router must not be powered cycled during the upgrade command.
