CableHome A project of CableLabs and technology suppliers to develop interface specifications for extending high-quality cable-based services to home network devices. It addresses issues such as device interoperability, QoS, and network management. CableHome will enable cable service providers to offer more services over HFC. It will improve consumer convenience by providing cable-delivered services throughout the home.

CableLabs A research consortium that defines the interface requirements for cable modems and acknowledges that tested equipment complies with DOCSIS.

cable modem A device installed at a subscriber location to provide data communications over an HFC network. Unless otherwise specified, all references to “cable modem” in this documentation refer to DOCSIS or Euro-DOCSIS cable modems only.

cable modem File containing operational parameters that a cable modem or gateway downloads from the cable configuration provider TFTP server during registration.

file

circuit-switchedNetwork-connection scheme used in the traditional PSTN telephone network where each connection requires a dedicated path for its duration. An alternative is packet-switched.

Class C network An IP network containing up to 253 hosts. Class C IP addresses are in the form “network.network.network.host.”

client

In a client/server architecture, a client is a computer that requests files or services such as file transfer,

 

remote login, or printing from the server. Also called a CPE.

 

On a WLAN, a client is any host that can communicate with the access point. A wireless client is also

 

called a “station.”

CMTS

A cable modem termination system is a device in the cable system headend that interfaces the HFC

 

network to local or remote IP networks to connecting IP hosts, cable modems or gateways, and

 

subscribers. It manages all cable modem bandwidth. It is sometimes called an edge router.

CNR

carrier to noise ratio

coaxial cable

A type of cable consisting of a center wire surrounded by insulation and a grounded shield of braided

(coax)

wire. The shield minimizes electrical and radio frequency interference. Coaxial cable has high

 

bandwidth and can support transmission over long distances.

CoS

Class of service traffic management or scheduling functions are performed when transferring data

 

upstream or downstream on HFC.

CPE

Customer premise equipment, typically computers, printers, etc., are connected to the cable modem

 

or gateway at the subscriber location. CPE can be provided by the subscriber or the cable provider.

 

Also called a client.

crosstalk

Undesired signal interfering with the desired signal.

CSMA/CD

carrier sense multiple access with collision detection
