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.

WIC-2AM-V2, WIC-1AM-V2 specifications

Cisco Systems is a leader in networking technology and offers a wide range of products designed to facilitate connectivity and enhance network performance. Among these products are the WIC-1AM-V2 and WIC-2AM-V2, which are modular interface cards designed specifically for Cisco routers. These interface cards provide additional capabilities that are essential for modern network infrastructures.

The WIC-1AM-V2 is a single-port asynchronous serial interface card, while the WIC-2AM-V2 offers two ports. Both cards are designed to support asynchronous serial connections and are commonly used for connecting devices like point-of-sale systems, industrial equipment, and other legacy systems that require serial communications. One of the key characteristics of these interface cards is their ability to integrate seamlessly into existing Cisco routing platforms, thus enhancing the flexibility and scalability of the network.

One of the main features of the WIC-1AM-V2 and WIC-2AM-V2 is their support for a range of communication protocols, including but not limited to, PPP (Point-to-Point Protocol), SLIP (Serial Line Internet Protocol), and HDLC (High-Level Data Link Control). This versatility is crucial for organizations that rely on various devices with differing communication standards. Furthermore, these cards support a maximum data rate of 115.2 kbps, ensuring that data can be transmitted efficiently over the serial connections.

Another significant technology embodied in these WICs is their ability to be hot-swappable, allowing for upgrades and maintenance without requiring complete network downtime. This feature is essential for businesses that demand high availability and minimal disruption to their operations. The compatibility of the cards with multiple Cisco router models further enhances their appeal, making them a versatile choice for network managers.

In conclusion, Cisco's WIC-1AM-V2 and WIC-2AM-V2 cards provide essential functionality for modern networks that require serial connectivity. With their robust support for various communication protocols, hot-swappable design, and seamless integration with Cisco routers, these interface cards are a valuable asset for any organization looking to enhance its network capabilities. Their reliability and performance make them a go-to choice for a wide range of applications, ensuring that businesses can maintain connectivity across diverse environments.
