This Cisco uBR910 Series Software Configuration Guide describes the configuration of the Cisco uBR910 series broadband cable data service unit (DSU), which includes the Cisco uBR914 DSU.
This section describes the following topics:
This configuration guide is designed for system administrators who have some experience downloading software from the World Wide Web and configuring DOCSIS cable modem systems. This guide is also directed to the network administrators who are responsible for administering the customer's local area network.
All users should have some experience with configuring Cisco routers and using the Cisco IOS command-line interface (CLI). A basic familiarity with DOCSIS 1.0 and quality of service (QoS) principles is also helpful.
Cable system installers and technicians should be familiar with their cable plant's base operating parameters and subscriber service offerings. Cable system support engineers and administrators should be acquainted with cable data networks and WAN communications protocols. Network administrators should be familiar with the principles of IP routing and subnetting; some of the advanced configurations also require a thorough understanding of access lists and how to use them.

Note This document contains instructions to install or configure the Cisco uBR910 series DSU using procedures that only qualified personnel should perform. This document is not intended for subscribers. Refer to the "Subscriber Publications" section for a list of documents available for subscribers. |
This configuration guide explains the initial and basic software configuration procedures for the Cisco uBR910 series DSU.
