HM200c/HM201c

Glossary

10BaseT

An unshielded, twisted pair cable with RJ-45 connectors

 

used with an Ethernet LAN. "10" indicates the speed (10

 

Mbps), "Base" refers to baseband technology, and "T"

 

means twisted pair cable.

Asymmetric

A system in which one spectrum of signal frequencies is

Scheme

assigned to signals moving in one direction and another

 

spectrum of signal frequencies is assigned to signals

 

moving in the opposite direction. Typically, higher

 

frequencies flow downstream and lower frequencies flow

 

upstream.

Bandwidth

The range of frequencies that can be transmitted on a

 

communication channel without exceeding loss or

 

distortion limits. Bandwidth indicates the

 

information-carrying capacity of a channel.

Baseline Privacy

The baseline privacy interface (BPI) provides cable

Interface

modem users with data privacy across the cable network

 

by encrypting data traffic between user's cable modem

 

and CMTS.

Bridge

An electronic device that provides a logical connection

 

path between two network segments.

Browser

A computer program used for accessing the World Wide

 

Web.

Cable Modem

The Cable Modem Termination System (CMTS) is the

Termination

major component of the headend. It interfaces to the

System (CMTS)

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.

Cable Network

The system of headend equipment and cables that

 

provides cable service (Internet and/or Television) to

 

individual homes and businesses.

CATV

A cable television network system.

CMTS

See Cable Modem Termination System

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.

Data Interface

The link that provides the communication channel

Connection

between two or more devices, allowing them to pass data

 

to one another.

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.
