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.

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.
