High Availability

For reliable access to the Internet and corporate networks, the ISDN port on the Cisco 1712, and the analog modem
port on the Cisco 1711 Router, provide a redundant backup WAN connection to failover should the primary WAN
connection fail (Figure 3). Additionally, Cisco 1711 and 1712 routers with Cisco IOS Software, which can
automatically detect WAN failures and reestablish connectivity through the backup link. Cisco IOS Software is the
industry proven software that has become the standard for reliable business access, and allows businesses to avoid
productivity losses resulting from interruptions in WAN connectivity.
