Glossary-2
A facility that provides a data transfer service among the equipment attached to
a network.
Equipment at the end user premises. This equipment may be provided by the
end user or service provider.
The Data-Over-Cable Service Interface Specifications.
The direction of data flow from a CMTS to a cable modem.
A protocol that allows dynamic assignment of IP addresses to other computers.
DHCP is also used to assign IP addresses to cable modems. This protocol can
also provide other parameters such as a TFTP server address and TFTP path
and filename.
A method of encoding data.
A key that is used to encrypt data to deter unauthorized interception.
A networking standard running at speeds of 10 Mbps (10BaseT) or 100 Mbps
(100BaseT).
The physical address of the Ethernet port. It is also known as a MAC address or
a NIC address.
A card that resides in an expansion slot of a PC. It can be a built-in Ethernet
port or an Ethernet port with a 10BaseT adapter. The Ethernet card takes data
from the computer, converts it to serial data, puts it into a packet format, and
sends it over the 10BaseT or 100BaseT LAN.
The Ethernet card has a 48-bit address burned into the ROM. It is also referred
to as a Network Interface Card (NIC).
A message generated by a cable modem to inform an operator that something
has occurred.
Connector on a cable modem that connects it to the cable system.
A protocol that allows users to log into a remote system, identify themselves,
list remote directories, and copy files to and from the remote machine. FTP
understands a few basic file formats. It is more complex than Telnet in that it
maintains separate TCP connections for control and data transfer.
A method of preventing a network from unauthorized access by filtering access
packets. This is done by the software on a cable modem or a dedicated server.
A technique for correcting errors incurred in transmission over a
communications channel by the receiver, without requiring the retransmission
of information by the transmitter; typically it involves a convolution of the
transmitted bits and the appending of extra bits, using a common algorithm by
the receiver and transmitter.
The central office of the service provider where cable signals originate.
Industry organization that defines a set of standards for home phoneline
networking technologies (www.homephna.org).
