Glossary
10BaseT | An unshielded, twisted pair cable with |
| 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 |
| |
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. |
