Understanding Basic Hardware Architecture and
Cisco IOS Software
Note The information herein applies to the Cisco AS5350, Cisco AS5400, and Cisco AS5400HPX universal
gateways. Note that the latter requires use of Cisco IOS release 12.2(2)XB or later.
This chapter provides a brief profile of the Cisco AS5350 and Cisco AS5400 universal gateway
hardware components and functionality, details how to use the Cisco IOS command-line interface (CLI),
and describes how to upgrade your Cisco IOS software:

The Cisco AS5350 and Cisco AS5400 universal gateways are versatile data and voice communications
platforms that provide the functions of a gateway, router, and digital modems in a single modular chassis.
The gateways are intended for Internet service providers (ISPs), telecommunications carriers, and other
service providers that offer managed Internet connections, and also medium to large sites that provide
both digital and analog access to users on an enterprise network.
Basic Hardware Architecture
Note The cards that reside in the AS5350 and AS5400 chassis, sometimes referred to as dial feature cards
(DFC), are of two types: trunk cards, which provide an E1, T1, or T3 interface, and universal port cards,
which host the universal digital signal processors (DSPs) that dynamically handle voice, dial, and fax
calls.
Figure 1-1 shows the logical and physical system architecture for the Cisco AS5350 and Cisco AS5400,
and illustrates the components used to process a call.
