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.

Note Descriptions and examples of software commands appear in this document only when they are necessary for installing the system hardware. For software configuration information, refer to the Cisco AS5850 Universal Gateway Commissioning Guidelines that shipped with your system, or the Cisco AS5850 Universal Gateway Operation, Administration, Maintenance, and Provisioning Guide.
