Applications
Business-Class DSL with WAN Backup
The Cisco 1900, 2900, and 3900 Series ISRs offer multiple WAN slots. These routers can be configured with an
EHWIC-VA-DSL card for primary WAN access, providing redundancy for mission-critical applications. The WAN
flexibility in these platforms enables the EHWIC-VA-DSL card to be swapped for any applicable HWIC or EHWIC,
depending on business need.
Banking Application
In this scenario, a bank branch office uses the Cisco 2911 with an EHWIC-VA-DSL card and ISDN Basic Rate
Interface (BRI) WAN interface card (WIC) to provide primary and backup WAN access. In addition, the 8-port
asynchronous and synchronous HWIC (HWIC-8A/S) can be used as a communication interface for ATM
machines. This scenario uses the versatility of the Cisco 2911 to enable banking databases to synchronize ATM
transactions without any interruption of WAN access, and it provides redundancy for other mission-critical
applications.
Business-Class Security
The Cisco 1900, 2900, and 3900 Series routers with the EHWIC-VA-DSL card can be optimized for Internet
security with the Cisco IOS Firewall, supporting stateful-inspection-firewall and intrusion-prevention-system
features. With an always-on DSL connection, Internet security is crucial to protecting corporate resources from
malicious network attacks. You can enable these features on the modular routers by purchasing the optional Cisco
IOS Software with the Advanced Security or later feature set.
