DOCSIS 1.0/ 1.1 Equivalent Cable Modem
Appendix C: Glossary
Bandwidth
Amount of data that can be transmitted per time.
Baseline Privacy Interface
The baseline privacy interface (BPI) provides cable modem users with data privacy across the cable network by encrypting data traffic between user's cable modem and CMTS.
BER
Bit Error Rate
Browser
A computer program that lets users access and display information from the World Wide Web. Two of the most commonly used browsers are Netscape Navigator and Microsoft Internet Explorer.
CATV
A cable television network system.
CCCM
CPE Controlled Cable Modems
CMTS (Cable Modem Termination System)
The Cable Modem Termination System (CMTS) is the major component of the headend. It interfaces to the cable network, the backbone data network, and several support systems. The CMTS also controls the configuration, registration, and media access of all the cable modems under its control, and determines who gets to transmit when, and for how long.
Coaxial Cable
Coaxial cable ("coax") allows wide bandwidth transmission over long distances. The coax cable is composed of an inner wire surrounded by an outer conductive shield.
CPE
Customer premises equipment
Decryption
The conversion of a coded (encrypted) signal to its original form, by means of an algorithm.
Demodulation
The process of recovering, at the receiver, an original transmitted signal that has been modulated.
Demodulator
A/D, demodulation, error correction, MPEG synchronization
