Banking Application
In this scenario (refer to Figure 3), a bank branch is able to use the Cisco 2811 ISR with an ADSL2+ HWIC and ISDN Basic Rate Interface (BRI)
WIC to provide primary and backup WAN access. In addition, the 8-port asynchronous/synchronous HWIC (HWIC-8A/S) is used as an interface
to ATM machines. This scenario further highlights the versatility of the Cisco 2811 because it enables the banking databases to update any ATM
transactions that take place while continuing to provide WAN access and redundancy for mission-critical applications.

Business-Class Security
The Cisco 1841 ISR and the Cisco 2800 and 3800 series of ISRs with the ADSL2+ HWICs 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
vital to protect corporate resources from malicious network attacks. These features can be enabled on the modular routers by purchasing the optional
Cisco IOS Software with the Advanced Security or higher feature set.
These platforms can also be optimized for VPNs, which allow secure use of the Internet for communications with the same policies and levels of
security and performance as a private network. VPNs provide security through encryption tunneling, and the Cisco routers support hardware-based
Triple Data Encryption Standard (3DES) IP Security (IPSec) and Advanced Encryption Standard (AES) support. Encryption features can be enabled
on the routers by purchasing the optional Cisco Advanced Security IOS Software.
IP and ATM Quality of Service
The Cisco 1841 ISR and the Cisco 2800 and 3800 series of ISRs with the ADSL2+ HWIC help service providers offer differentiated service options
based on premium, standard, or best-effort service classes. The routers employ QoS features such as application-aware networking with IP QoS
features and traffic management with ATM CoS features.
