Overview
The Cisco 800 series routers connect small professional offices or telecommuters over Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) lines to the Corporate LANs and the Internet. The routers offer bridging and multiprotocol routing capability between LAN and WAN ports.

Feature Summary
Table 1-1 summarizes the features of the Cisco 800 series routers.
Table 1-1 Cisco 800 Series Feature Summary
10BASE-T Ethernet port(s)
All
Provides connection to 10BASE-T (10 Mbps) Ethernet networks. Compatible with 10/100-Mbps devices.
ISDN BRI S/T port
Cisco 801 and 803
Provides connection to ISDN S/T network.
ISDN BRI U port
Cisco 802 and 804
Provides connection to ISDN U network.
IDSL port
Cisco 802 IDSL and 804 IDSL
Provides connection to IDSL network.
Telephone ports
Cisco 803 and 804
Provide connection to telephone, fax machine, or modem, which are connected to telephone services through ISDN line.
Internal Network Termination 1 (NT1)
Cisco 802 and 804
Eliminates need for an external NT1 in North America.1
Flash memory
All
8 MB of Flash memory.2
Dynamic RAM (DRAM)
All
4 MB of DRAM.2
Easily distinguishable ISDN B-channel LEDs
All
ISDN B-channel LEDs in a different color from other LEDs.
Ease of installation
All
Color-coded ports and cables to reduce the chance of error.
Cisco IOS software
All
Supports Cisco IOS software.
Cisco 800 Fast Step application
All
Provides a Windows 95-, Windows 98-, and Windows NT-based software tool for basic configurations.
Console port
All
Provides connection to terminal or PC for software configuration using command-line interface and for troubleshooting.
Note
Cable lock
All
Provides a way to physically secure the router.
Locking power connector
All
Locks power connector in place.
Wall-mount feature
All
Brackets on router bottom provide a way to mount router on wall or vertical surface.
1 Although the ISDN U interfaces on the Cisco 802 and Cisco 804 routers provide internal NT1s, the routers themselves do not function as NT1s. You cannot connect S/T devices to Cisco 802 and Cisco 804 routers.
2 An additional 8 MB of Flash memory and 4 or 8 MB of DRAM can be added at the factory or later. You can order upgrade kits and have trained and qualified personnel add the memory. The Cisco product number for the 8-MB Flash memory upgrade kit is MEM800-8F and the numbers for the DRAM upgrade kits are MEM800-4D and MEM800-8D.

If the symbol of suitability (
) appears above a port, you can connect the port directly to a public network that follows the European Union standards.
Warning
) appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage your router.
