The Cisco 801–804 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 or fax machines, which 
are connected to telephone services through an ISDN line.

Flash memory: Default is 8 MB, expandable to 12 MB. (4MB Flash soldered to the motherboard.)

To add additional Flash memory to the Cisco 801–804, remove the existing Flash card and install a 
new one. 

Dynamic RAM: Default is 4 MB, expandable to 12 MB. (4MB Dynamic RAM soldered to the 
motherboard.)

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