Data Sheet

One- and two-port analog modem WAN interface cards (WICs; part numbers WIC-1AM-V2 and WIC-2AM-V2) are now available for the award-winning Cisco® 1800, 2600XM, 2691, 2800, 3700, and 3800 Series modular router platforms. The new version of these cards expands the already extensive range of WICs 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 1800, 2600XM, 2691, 2800, 3700, and 3800 Series routers offer customers
best-of-breed scalability, flexibility, and investment protection-all in cost-effective, multifunctional platforms.

Figure 1. One- and Two-Port Analog Modem WICs for Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 Series Platforms

Both cards feature dual RJ-11 connectors, which are used for basic telephone service connection. The 2-port card uses one port for connection to a standard telephone line and the other port for connection to a basic analog telephone for use when the modem is idle.

KEY BENEFITS

Combined with the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800, the cards provide:

• An integrated solution for ease of deployment and management

• Enhanced remote management capabilities

• A cost-effective alternative to leased lines or ISDN

• On-demand dial backup for critical WAN links

KEY FEATURES

Equipped with the new integrated analog modem WICs, the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 offer the most flexible, scalable, and manageable telephone dial access solution available on the market today.

• Internal analog modem dialup capability-Internal modems allow simple setup of a remote router. There is no separate external power and no cables, and everything is in one chassis.

• Support for speeds up to 56K (V.92 specification)-When dialing out to a digital endpoint, this feature allows users to achieve maximum data transfer rates, equating to faster file transfers, speedier Web access, and faster e-mail downloads.

• Cisco IOS Dial Access Software-Cisco IOS Software provides a broad range of features for remote router management and dial backup, including:

– Reverse Telnet support for LAN-based dial- and fax-out

– Point-to-Point Protocol (PPP), Multilink PPP (MLPPP), and Serial Line Internet Protocol (SLIP)

– TACACS+, RADIUS, and PPP password security

– Autosensing Internetwork Packet Exchange (IPX), Transmission Control Protocol/IP (TCP/IP), AppleTalk Remote Access (ARA), and AppleTalk Control Protocol (ATCP)

APPLICATIONS

Remote Router Management

Figure 2. Remote Router Management

The cards are ideal for dialup access for remote router configuration and management (Figure 2). Similar to connecting a modem to the router auxiliary port, the modem WICs allow out-of-band management through an internal device. Both WICs can receive calls at speeds as fast as 33.6 kbps, depending upon line conditions.

Dial Backup and Asynchronous DDR

Figure 3. Dial Backup and Asynchronous

Constant WAN access is often a requirement for branch offices connecting to a corporate site or the Internet. Although DSL, Frame Relay, ISDN, and leased line are common choices for a primary WAN link, an alternate data path is sometimes needed. The WICs combined with the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 offer the ability to automatically dial a backup connection when the primary WAN link is unavailable. In addition, the modem WICs can also be used to provide supplemental bandwidth when the primary WAN link is overused. 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 require only a dialup connection, the Cisco routers with the integrated modem WIC 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- and Fax-Out Modem Access

Figure 4. Dial- and Fax-Out Modem Access

The modem WICs comply with RFC 2217 and provide dial- and fax-out modem functions 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 WICs as if they were connected directly to their PC communications port, allowing convenient access to services such as America Online, CompuServe, and remote fax machines without requiring dedicated phone lines and modems at each PC.

Note: The WICs do not have the ability to receive faxes; only fax-out is supported.

Low-Density Analog RAS Access

Figure 5. Low-Density Analog RAS Access

Dial-in users can take advantage of the ability of the router to function as a small RAS, thus allowing dialup access to the LAN (Figure 5). Typically, a 2-port modem WIC would be used here for maximum port density, but the 1-port WIC is also acceptable. Scalability to multiple modem WICs per chassis (up to 12 in a Cisco 3845-refer to Table 3) is also possible. Dial-in speeds of up to 33.6 kbps (V.34bis) are possible. MLPPP is available to bond two or more calls together, thereby allowing higher-speed RAS support.
