Cisco 1800 Fixed-Configuration Integrated Services are the next evolution of the award-winning Cisco 1700 Series modular access routers. The Cisco 1800 Series fixed-configuration routers are designed for secured broadband access, Metro Ethernet, and wireless connectivity. They also help businesses reduce costs by enabling deployment of a single device to provide multiple services typically performed by separate devices.
The Cisco 1803 Integrated Services Router provides:
Cisco 1801, 1802, and 1803 routers provide high-speed DSL broadband access through asymmetric DSL (ADSL) over basic telephone service (Cisco 1801), ADSL 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 1801, 1802, and 1803 routers combine the cost benefits of DSL service with the advanced routing capability required for business use of the Internet.
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.
