Product Overview

Cisco 1800 Series integrated services routers are the next evolution of the award-winning Cisco 1700 Series modular and fixed-configuration routers. The Cisco 1801, 1802, 1803, 1811, and 1812 integrated services routers (Figure 1) are fixed-configuration, while the Cisco 1841 Integrated Services Router is modular. The routers are designed for secure broadband, Metro Ethernet, and wireless connectivity, and provide significant performance improvements, feature capability, versatility, and additional value compared to prior generations of Cisco 1700 Series. The Cisco 1800 Series fixed-configuration routers provide:
Secure broadband access with concurrent services for branch and small offices
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

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 fixed­configuration 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.

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 high­performance and high-availability, mission-critical business applications.

Integrated Wireless LAN Capability

Cisco 1800 Series fixed-configuration routers offer models with an integrated wireless access point, providing secure router and secure wireless LAN services in one device, helping businesses reduce total cost of ownership with simplified WLAN deployment and management capabilities. The integrated wireless access point supports IEEE
802.11a/b/g simultaneously to provide high-speed wireless capability and flexibility to support 2.4 GHz and 5 GHz dual-band simultaneous operation, making them ideal choices for wireless hotspot deployments and wireless office solutions. Cisco Aironet®, Wi-Fi Certified and Cisco Compatible client devices are fully supported.
The Cisco 1800 Series routers with integrated wireless access points are Wi-Fi Certified and support Wi-Fi Protected Access (WPA and WPA2) providing secure mutual authentication and encryption via Cisco IOS Software features to meet the strict demands of today's businesses. These products also provide support for multiple wireless VLANs that can be configured to provide additional security, segmentation, and separation of user groups. When using the routers in conjunction with the Cisco Service Selection Gateway (SSG) and Subscriber Edge Services Manager (SESM), managed service providers can incorporate service-based authorization and accounting, and service and subscriber management for customizable, on-demand wireless services such as hotspots. Additional features such as local authentication allow users to maintain wireless connectivity to the router in the event that a remote authentication server goes down.
Figure 5 shows a Cisco 1800 Series fixed-configuration wireless router deployed in a small branch-office WLAN application.

Business-Class DSL and Ethernet Connectivity

The Cisco 1801, 1802, and 1803 routers combine the cost benefits of DSL service with the advanced routing capability required for business use of the Internet. These products are available as ADSL over POTS (Cisco 1801), ADSL over ISDN (Cisco 1802), or G.SHDSL (Cisco 1803). They deliver strong network security, QoS, and other Cisco IOS features at broadband speeds. Enhanced DSL QoS features, such as Weighted Random Early Detection

(WRED), committed access rate (CAR), and Class-Based Traffic Shaping, help ensure high performance for mission-critical applications. The Cisco 1803 supports G.SHDSL 2-wire and 4-wire capability providing longer reach and higher performance.
The Cisco 1811 and 1812 routers are focused on Ethernet access and are designed to be offered as customer premises equipment (CPE) in Metro Ethernet deployments. Because of their high-speed performance and dual Fast Ethernet WAN ports, they can support the high-bandwidth demands of Metro Ethernet and provide failover protection and load balancing if desired.
The eight-port switch on the Cisco 1800 Series fixed configuration routers is sufficient for connecting numerous devices and the optional PoE capability can supply power to IP telephones or other devices.
