    • Integrated ISDN Basic Rate Interface (BRI), analog modem, or Ethernet backup port for redundant WAN links and load balancing

    • Secure wireless LAN for simultaneous 802.11a and 802.11b/g operation with use of multiple antennas

    • Advanced security including:

    – Sophisticated Firewall features including Application Inspection, Transparent and Stateful Firewall

    – SSL and IP Security (IPSec) VPNs (Triple Data Encryption Standard [3DES] or Advanced Encryption Standard [AES])

    – Intrusion Prevention System (IPS)

    – Antivirus support through Network Admission Control (NAC) and enforcement of secure access policies

    • 8-port 10/100 managed switch with VLAN support and optional Power over Ethernet (PoE)

    • Easy deployment and remote-management capabilities through Web-based tools and Cisco IOS® Software

    Cisco 1801, 1802, and 1803 routers provide high-speed DSL broadband access through asymmetric DSL (ADSL2/2+ Annex A and Annex M) over basic telephone service (Cisco 1801), ADSL2/2+ Annex B over ISDN (Cisco 1802), or Symmetrical High-Data-Rate DSL (G.SHDSL) (Cisco 1803) while helping to ensure reliable networking with integrated ISDN S/T BRI backup. The Cisco 1811 and 1812 provide high-speed broadband or Ethernet access through two 10/100BASE-T Fast Ethernet WAN ports and also provide integrated WAN backup through a V.92 analog modem (Cisco 1811) or ISDN S/T BRI interface (Cisco 1812).
    The Cisco 1800 Series fixed-configuration routers help enable a network infrastructure for SMBs and enterprise small branch offices, providing access to the Internet, corporate headquarters, or other remote offices, while securing and protecting critical data with integrated Cisco IOS Software security features and capabilities. They also help businesses reduce costs by enabling deployment of a single device to provide multiple services (integrated router with redundant link, LAN switch, firewall, VPN, IPS, wireless technology, and quality of service [QoS]) typically performed by separate devices. Cisco IOS Software allows this flexibility, providing the industry's most robust, scalable, and feature-rich internetworking support, using the accepted standard networking software for the Internet and private WANs.

    Network Applications

    Secure Network Connectivity

    Network security has become a fundamental building block of any network, and Cisco routers play an important role in embedding security at the customer's access edge. Recognizing this requirement, the Cisco 1800 Series fixed-configuration routers are equipped with the Cisco IOS Software Advanced IP Services feature set by default (except for the Cisco 1801). This Cisco IOS Software feature set facilitates hardware-based IPSec encryption on the motherboard and provides a robust array of security capabilities such as Cisco IOS Firewall, URL Filtering, IPS support, IPSec VPNs (DES, 3DES, and AES), Tunnel-less Group Encrypted VPN (GET VPN), Dynamic Multipoint VPN (DMVPN), Easy VPN server and client support, NAC for defense against worms and viruses, security policy enforcement, Secure Shell (SSH) Protocol Version 2.0, and Simple Network Management Protocol (SNMP) in one solution set. As Figure 2 demonstrates, the Cisco 1800 Series fixed-configuration routers help enable customers to deploy high-performance, concurrent, mission-critical data applications with integrated, end-to-end security.

    Figure 2. Securing Small Branch Office with a Cisco 1800 Series Fixed-Configuration Router

    Highly Available Internet Connection

    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) and reliable static routing using object tracking. Each of the Cisco 1800 Series fixed-configuration 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 is disconnected for some reason, the router will detect this failure and will fail over to the secondary backup WAN. As Figure 3 and 4 demonstrate, the Cisco 1800 Series fixed-configuration routers help enable customers to deliver high-performance and high-availability, mission-critical business applications.
