Getting to Know Your Cable Modem
This chapter provides overview of your Prestige 941 Cable Modem, its key features, applications and
product specifications.
1.1 Prestige 941 Cable Modem
The Prestige 941 is a high bandwidth Internet access cable modem that connects your LAN to the Internet
using the hybrid fiber coaxial (HFC) cable; the same cable that brings television into a cable television
(CATV) subscriber’s home. With the Prestige 941 cable modem, a personal computer can be connected to
the HFC cable network for high-speed access to the Internet. It is ideal for cable users with more than one
PC and is an excellent alternative to the more expensive leased lines.
The Prestige 941 cable modems are based on the Multimedia Cable Network System (MCNS) Data Over
Cable Service Interface Specification (DOCSIS) standards specifications. MCNS is a consortium of cable
television companies whose goal is to create standards for interoperable data-over-cable systems.
The Prestige 941 cable modem operates with one external AC-input power supply.
1.2 Overview of Cable Data System Operation
The Cable Data System includes CMTS (Cable Modem Termination System, or called Headend) at Cable
Operator site, Cable Network Plant and Cable Modems. The cable headend must be properly configured to
successfully install the Prestige 941 cable modem.
The Prestige 941 cable modem is configured automatically using a configuration file generated by the cable
operator and delivered by the cable headend. The headend provides a path to the Prestige 941 cable modem
for both the DHCP (Dynamic Host Control Protocol) server and IP address assignment.
