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 with built-in ADSL over POTS (Cisco 1801), ADSL over ISDN (Cisco 1802), or G.SHDSL (Cisco 1803)

WAN port. 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 G.SHDSL interface on the Cisco 1803 supports standards based 4-wire capability providing longer reach and

higher bandwidth performance.

The Cisco 1811 and 1812 routers offer the flexibility to connect to broadband DSL modems, Cable modems, or Ethernet access services. For

Ethernet access, these routers are designed to be 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 integrated eight port switch is sufficient for connecting numerous devices and the optional PoE capability can supply

power to IP telephones or other IEEE 802.3af compliant devices.

KEY 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 to deploy 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.

Benefit

High-speed processor delivers exceptional processing power for routing applications and concurrent

security and wireless services.

Eliminates the need to deploy and manage a separate DSL modem.

Offers flexibility to connect to various types of DSL broadband or cable access or Ethernet access.

Additional capability to deploy redundant WAN connections for failover protections and load balancing.

Fully managed LAN switch ports connect multiple LAN devices and reduce the need for an additional

LAN switch.

Built-in ISDN S/T BRI or analog modem port provides high availability by establishing a backup WAN

connection if the primary connection fails.

Delivers high-speed IPSec encryption and decryption rates for DES, 3DES, and AES to help ensure all

available bandwidth to the Internet is utilized for maximum performance.

The default memory of 32-MB Flash and 128-MB DRAM is sufficient to support complex configurations

and advanced services and help ensure operation for an extended period. Memory is expandable to

support maximum of 128-MB Flash and 384-MB DRAM, offering additional investment protection.
