Integrated V.90 Modem
WAN Interface CardsOne- and two-port analog modem WAN Interface Cards (Part numbers WIC-1AM and WIC-2AM) are now available for the award-winning Cisco 1700, 2600, 3600, and 3700 Series modular router platforms. The addition expands the already extensive range of WAN Interface Cards currently available for these routers (Figure 1). The interface cards provide cost-effective basic telephone service connectivity to allow remote router management, asynchronous Dial-on-Demand Routing (DDR) and dial backup, dial- and fax-out modem access, and low-density remote access server (RAS) services. Combined with the differentiated services delivered through Cisco IOS® Software, the Cisco 1700, 2600, 3600, and 3700 Series routers offer customers best-of-breed scalability, flexibility, and investment protection, all in cost-effective, multifunctional platforms.

Both cards feature dual RJ-11 connectors, which are used for basic telephone service connection. The WIC-1AM uses one port for connection to a standard telephone line, and the other port can be connected to a basic analog telephone for use when the modem is idle.
Key Benefits
Combined with the Cisco 1700, 2600, 3600, and 3700, the WIC-1AM and WIC-2AM cards provide:
•
An integrated solution for ease of deployment and management

Key Features
The Cisco 1700, 2600, 3600, and 3700, equipped with the new integrated analog modem WAN interface cards, offer the most flexible, scalable, and manageable Plain Old Telephone Service (POTS) dial access solution available on the market today.

Applications
Remote Router Management
Figure 2 Remote Router Management
The WIC-1AM and WIC-2AM cards are ideal for dialup access for remote router configuration and management (Figure 2). Similar to connecting a modem to the router's auxiliary port, the modem WAN Interface Cards allow out-of-band management through an internal device. Both WAN Interface Cards can receive calls at speeds as fast as 33.6K, depending upon line conditions.
Dial Backup and Asynchronous DDR
Figure 3 Dial Backup and Asynchronous DDR
Constant WAN access is often a requirement for branch offices connecting to a corporate site or the Internet. While DSL, Frame Relay, ISDN, and leased line are common choices for a primary WAN link, an alternate data path is sometimes needed. The WIC-1AM and WIC-2AM cards combined with the Cisco 1700, 2600, 3600, and 3700 offer the ability to automatically dial a backup connection when the primary WAN link is unavailable. In addition, the modem WAN Interface Cards can also be used to provide supplemental bandwidth when the primary WAN link is overutilized. Multiple modem calls can be aggregated using MLPPP when one 56K connection is insufficient.
For some customers, dialup telephone service connectivity may be the only available choice for WAN access to the Internet or to a corporate home office. For those situations and for those installations that only require a dialup connection, the Cisco Series Routers with integrated modem WAN Interface Card offer WAN connectivity through Asynchronous DDR. As in the case of dial-backup, MLPPP can be used to aggregate multiple dialup connections into one data stream, providing higher throughput.
Dial-Out and Fax-Out Modem Access
Figure 4 Dial- and Fax-Out Modem Access
The WIC-1AM and WIC-2AM cards comply with RFC-2217 and provide dial-out and fax-out modem functionality to LAN-connected devices (Figure 4). Using the recommended "Advanced COM Port Redirection" software (available from http://www.tacticalsoftware.com), customers can take advantage of the modem WAN Interface Cards as if they were connected directly to their PC's communications port. This allows convenient access to services such as America Online, CompuServe, and remote fax machines without requiring dedicated phone lines and modems at each PC.

Note:
Low-Density Analog RAS Access
Figure 5 Low-Density Analog RAS Access
Dial-in users can take advantage of the router's ability to function as a small remote access server (RAS), thus allowing dialup access to the LAN (Figure 5). Typically, a two-port modem WAN Interface Card would be used here for maximum port density, but the WIC-1AM is also acceptable. Scalability to multiple modem WAN Interface Cards per chassis (up to 12 in a Cisco 3660 Multiservice Platform) is also possible. Dial-in speeds of up to 33.6K (V.34bis) are possible. MLPPP is available to bond two or more calls together, therefore allowing higher speed RAS support.
