DOCSIS 1.0/ 1.1 Equivalent Cable Modem

 

Headend 

The aggregation point in a CATV plant where control equipment is located. The 
CMTS resides here, as does video broadcast and monitoring equipment.

 

 
HFC (Hybrid Fibre/Coax) 

A cable system where the cables closest to the Headend are fiber technology, and the 
cables dropped into individual homes are coaxial. Between these two ends, the signal 
is converted from fiber to coaxial. The coaxial cable then runs through the branches of 
the network and is finally dropped into the home. 

 
Hub 

Electronic device that accepts data from a sending computer and delivers it to the 
appropriate destination. Many networks are shaped like a wheel with different 
computers attached at the ends of the wheel’s spokes; the hub is the center of the wheel 

 
ICMP 

Part of the TCP/IP protocol used for network diagnosis. 

 
IEEE 802.3 

IEEE is the Institute for Electrical and Electronic Engineers. 802.3 refers to the 
specifications of the Ethernet protocol. 

 
ISP 

Internet Service Provider. A commercial organization that provides access to the 
Internet for its subscribers

 

 
IP 

Internet Protocol. IP is a standard that defines the format of packets of information sent 
over the Internet and the mechanism for routing each packet to its destination. IP is the 
network portion of TCP/IP, the most commonly used protocol suite for the Internet. 

 
IP Address 

A unique, 32-bit address assigned to every device in a network. An IP address is 
composed of a network address and a host address. Each network is assigned an 
address by a government agency, and each company administrator assigns an address 
to each host computer. 

 
 

Latenacy/(Lag) 

Excessive response time. Time between sending a request to a server (e.g. web page) 
and receiving the response. 

 
LED 

Light-Emitting Diode. A semiconductor device that emits light when voltage is applied 
between its terminals. LEDs are used on the cable modems as front panel lights. 

 
MAC Address 

The physical address of the Media Access Control device.
