78-10446-01

The Cisco 800 series routers provide the following key hardware features:

Cisco 802 and Cisco 804 routers have an integrated NT-1, which eliminates the need for an external
NT-1 in North America.

Cisco 803 and Cisco 804 routers provide connection to analog telephones, fax machines, or
modems, which are connected to telephone services through an Integrated Services Digital
Network (ISDN) line.

Flash memory: Default is 8 MB, expandable to 12 MB.

Dynamic RAM: Default is 4 MB, expandable to 12 MB.

ISDN B-channel LEDs are a different color from the other LEDs, which make them easy to
distinguish.

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked or mounted on a wall.

The feature packs described in these release notes contain Cisco IOS Release 12.0(7)XV software
images, some images from previous software releases, and the RSL Version 7.3.

To determine the version of Cisco IOS software running on your Cisco 800 series, log in to the router
