(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.
Key Features and Benefits
Architecture Features and Benefits
The Cisco 1800 Series fixed-configuration routers have been specifically architected to meet the requirements of
SMBs and enterprise branch offices as well as service provider-managed applications for concurrent services for
broadband access. The Cisco 1801, 1802, 1803, 1811, 1812, and 1841 routers together with other Cisco integrated
services routers such as the Cisco 800, 2800, and 3800 Series provide the broadest range of secure connectivity
options in the industry combined with high-availability features. In addition, Cisco IOS Software supports a complete
suite of transport protocols, QoS, and network security. Table 2 lists the architecture features and benefits of the
Cisco 1800 Series fixed-configuration routers.
