Cisco 1800 Series (Fixed-Configuration) Wireless Example PDA Printer PCs Branch Office Internet Cisco 1800 FixedConfiguration Router with integrated 802.11a/b/g access point Laptops File Server When to Deploy Deploy the Cisco 1800 Series fixedconfiguration routers when you need: • An application-specific configured router • Fully integrated DSL/Security/Wireless router • To support high performance Internet access • High availability Internet connections and load balancing • Easy to order products • Ability to connect several LAN devices High-Availability Features The Cisco IOS Software Advanced IP Services feature set offers basic and advanced routing capabilities to deliver failover protection and load balancing. These capabilities include Border Gateway Protocol (BGP), Open Shortest Path First (OSPF) Protocol, Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing Information Protocol (RIP) routing protocols along with dial-on-demand routing (DDR) Reliable Static Routing Using Object Tracking. Each of the Cisco 1800 Series fixedconfiguration routers is equipped with either an ISDN BRI, V.92 analog modem, or Ethernet port for secondary WAN backup connection. If the primary DSL, cable, or Ethernet-access WAN experiences a link failure or loss of connectivity, the router will detect this failure and will fail over to the secondary backup WAN. The Cisco 1800 Series fixed-configuration routers help enable customers to deliver high-performance and high-availability, mission-critical business applications. 26 High-Availability Features Example Cisco 1800 Series (Fixed-Configuration) Headquarters Office Platform Overview Models Cisco 1801 Cisco 1802 Cisco 1803 Cisco 1811 Cisco 1812 FE WAN Switch Ports Ports WAN Compact Wireless DRAM (MB) Flash (MB) Power Option Default Max Default Max Supply 1 8 ADSL Yes 128 384 32 128 AC 1 8 ADSLoISDN Yes 128 384 32 128 AC 1 8 G.SHDSL Yes 128 384 32 128 AC 2 8 10/100 Ethernet Yes 128 384 32 128 AC 2 8 10/100 Ethernet Yes 128 384 32 128 AC Series Specifications Dimensions (H x W x D) Console Port Auxiliary Port USB Port Wireless LAN V.92 Analog Modem Port Integrated Channel Service Unit/Data Service Unit (CSU/DSU) Voice/Data Support Encryption 10/100 Switch Ports Integrated Modems Default 10/100 WAN Ports ISDN Basic Rate Interface (BRI) Ports S/T 12.5 x 9.5 in.
