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

The following Cisco multiservice platforms are supported for the Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WIC:

Cisco 2600XM

Cisco 2691

Cisco 2800

Cisco 3700

Cisco 3800

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

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

Platform Memory Requirements

Cisco 2600 ip —8M Flash, 32M DRAMM


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).

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

The Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WAN Interface Card adds the following features to WAN interface card modems:

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.

Three applications are available for the V.90 modem WIC on the Cisco 2600XM, Cisco 2691, Cisco 3700, and Cisco 3800 series multiservice platforms:

Remote Router Management and Out-of-Band Access

Asynchronous Dial-on-Demand Routing and Dial-Backup

Low-Density Analog RAS Access

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 theCis co 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.

Configuration Examples for Cisco WIC-1AM-V2 and WIC-2AM-V2 Analog Modem WIC

This section contains the following examples:

Configuring for Asynchronous Dial Backup: Example

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

Command Reference

This section documents new and modified commands. All other commands used with this feature are documented in the Cisco IOS Release 12.3 command reference publications.

New Commands

upgrade modem firmware

upgrade modem firmware

To upgrade the modem firmware, use the upgrade modem firmware command in global configuration mode.

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

Syntax Description

all

Select all the modems in the router that are supported by the modem firmware file.

slot

Select the modem in the specified router slot that are supported by the modem firmware file.

slot

Number of the slot selected.

wic

Select the modems in the specified router slot/wic_slot that are supported by the modem firmware file.

nm-slot

Number of the slot where the network module is located.

wic-slot

Number of the slot where the WIC is located.

file

Obtains the firmware information from the file named as source.

source

Name of the file with the firmware.


Defaults

No default behavior or values.

Command Modes

Global configuration mode.

Command History

Release
Modification

12.3(13)

This command was introduced.


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.

Examples

The following example shows output of the upgrade modem firmware all command with a 1-port WIC-1AM-V2 in 0/1 (slot/wic-slot) and a 2-port WIC-2AM-V2 in 1/0 (slot/wic-slot).:
