Cisco AS5850 Product Overview

The Cisco AS5850 is a high-density, ISDN and modem WAN aggregation system that provides both

digital and analog call termination. It is intended to be used in service provider dial point-of-presence

(POP) or centralized enterprise dial environments.

The gateway components include hybrid trunk and port-handling cards (both functions are handled by

different components in the same slot), dedicated port-handling cards, dedicated trunk cards, route

switch controllers, power entry modules, and a blower unit to cool the chassis. An optional 2400W AC

power shelf is also available. The gateway is designed with environmental monitoring and reporting

functions to help maintain normal system operation and resolve adverse environmental conditions prior

to loss of operation. If conditions reach critical thresholds, the system shuts down to avoid equipment

damage from excessive heat or electrical current.

Downloadable software and microcode allow you to load new software images into Flash memory

remotely, without having to physically access the universal gateway, for fast and reliable upgrades.

This chapter provides physical and functional overviews to familiarize you with your new

Cisco AS5850. The chapter also contains physical descriptions of system hardware and major

components and functional descriptions of component features.

Descriptions and examples of software commands appear in this document only when they are
