Glossary
This chapter defines terms used in this guide and in the industry.
Broadcast
A packet sent to all devices on a network.
Cable Modem Termination System (CMTS)
Typically located in the cable company’s headend, the CMTS is equipment that provides highspeed data services to subscribers, such as cable Internet and VoIP.
Channel Bonding
A computer networking configuration where two or more network interfaces are combined on
a host computer for redundancy or increased throughput. Data is transmitted over these
channels as if they are one channel.
Customer Premises Equipment (CPE)
Equipment such as telephones, routers, and modems located at a subscribers location to
enable customers access to communication services.
Default Gateway
The routing device used to forward all traffic that is not addressed to a computer on the local
subnet.
Demilitarized Zone (DMZ)
Allows one IP address (or computer) to be placed in between the firewall and the Internet
(usually for gaming and video conferencing). This allows risky, open access to the Internet.
Domain
A subnetwork comprised of a group of clients and servers under the control of one security
database.
Domain Name
A descriptive name for an address or group of addresses on the Internet. Domain names are
in the form of a registered entity name plus one of a number of predefined top-level suffixes,
such as .com, .edu, .org.
Domain Name System (DNS)
An Internet service that locates and translates domain names into IP addresses. Because
domain names are alphabetic, they are easier to remember. However, the Internet is based
on IP addresses. Every time you use a domain name, a DNS service translates the name into
the corresponding IP address. The DNS system is actually its own network. If one DNS server
does not know how to translate a particular domain name, it asks another one, and so on, until
the correct IP address is returned.
Downstream
A term to describe the direction of data from the network service provider to the customer.

Dynamic Host Configuration Protocol (DHCP)
A protocol that centrally automates the assignment of IP addresses (see IP Address) in a
network. Using the Internet’s set of protocols (TCP/IP) (see Transmission Control
Protocol/Internet Protocol (TCP/IP)) , each machine that can connect to the Internet needs a
unique IP address. For example, when the service provider sets up computer users with a
connection to the Internet, an IP address is assigned to each machine. DHCP lets the service
provider distribute IP addresses and automatically sends a new IP address when a computer
is plugged in to the high-speed Internet network. DHCP uses the concept of a “lease” or
amount of time an IP address is valid for a computer. Lease times can vary.
Ethernet
A standard network protocol that specifies how data is placed on and retrieved from a common
transmission medium. It forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS (see Xerox Network Services (XNS)) .
Firewall
A highly effective method to block unsolicited traffic from outside the connected computers in
your gateway.
Gateway
A local device, usually a router, that connects hosts on a local network to other networks –
sometimes with different incompatible communication protocols.
Headend
A main facility to process and distribute Internet communication signals. Headend may also
refer to cable television signals and power line communication facilities.
Internet Protocol (IP)
The method or protocol by which data is sent from one computer to another on the Internet. It
is a standard set of rules, procedures, or conventions relating to the format and timing of data
transmission between two computers that they must accept and use to understand each other.
Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP.
IP Address
In the most widely installed level of the IP today, an IP address is a 32-bit binary digit number
that identifies each sender or receiver of information that is sent in packet form across the
Internet. When you request a Web page or send an e-mail, the IP part of TCP/IP includes your
IP address. IP sends your IP address to the IP address obtained by looking up the domain
name in the URL (see Uniform Resource Locator (URL)) you requested or in the e-mail
address to which you are sending a note. A dynamic IP address is an IP address that is
automatically assigned to a client station in a TCP/IP network, typically by a DHCP server.
Internet Service Provider (ISP)
A company that provides individuals and companies access to the Internet and other related
services.
Interval Usage Code (IUC)
Interval usage codes define different profiles for upstream burst profiles to use for the data.
IUCs are sent to the cable modem from the CMTS to tell the device important characteristics
to use for the burst, such as modulation type, preamble length, and so on.

Glossary
Local Area Network (LAN)
A group of computers and associated devices such as printers and servers that share a
common communication line and other resources within a small geographic area.
Media Access Control (MAC) Address
A unique number assigned by the manufacturer to any Ethernet networking device, such as a
network adapter, that allows the network to identify it at the hardware level. Usually written in
the form 01:23:45:67:89:ab.
Megabits per Second (Mbps)
A unit of measurement for data transmission that represents one million bits per second.
Maximum Transmission Unit (MTU)
The size in bytes of the largest packet that can be sent or received.
Network Address Translation (NAT)
A technique by which several hosts or computers share a single IP address for access to the
Internet. NAT enables a LAN to use one set of IP addresses for internal traffic and a second
set of addresses for external traffic, and provides a type of firewall by hiding internal IP
addresses.
Network Basic Input Output System (NetBIOS)
An application programming interface (API) that augments the DOS BIOS by adding special
functions for LANs. Almost all Windows-based LANs for PCs are based on the NetBIOS.
Network Operations Center (NOC)
A location that controls computer, television, or telecommunications networks. Large
organizations usually have more than one network operations center to manage multiple
networks.
Packet
A block of information sent over a network. A packet typically contains a source and
destination network address, some protocol and length information, a block of data, and a
checksum.
Ranging
A process in which a cable modem sends a range request at a power of 8 dBmV (very low
power). If it does not rec i eve a range response from the CMTS, the cable modem re-transmits
the range request at a 3 dB higher power level and continues the process until a range
response is received.
Routing Information Protocol (RIP)
A protocol in which routers periodically exchange information with one another to determine
minimum-distance paths between sources and destinations.
Router
A device that forwards data between networks. An IP router forwards data based on IP source
and destination addresses.

Subnet
A portion of a network that shares a common address component. On TCP/IP networks,
subnets are defined as all devices whose IP addresses have the same prefix. For example, all
devices with IP addresses that start with 10.1.10 would be part of the same subnet. IP
networks are divided using a subnet mask.
Subnet Mask
Combined with the IP address, the IP subnet mask allows a device to know which other
addresses are local to it, and which must be reached through a gateway or router. A number
that explains which part of an IP address comprises the network address and which part is the
host address on that network.
Telnet
A network protocol used on the Internet or a local area network. Provides bi-directional
interactive text-oriented communications using a virtual terminal connection.
Terminal Access Controller Access-Control System (TACACS)
A remote authentication protocol used to communicate with an authentication server to
determine if the user is allowed to access the network.
Time Division Multiple Access (TDMA)
A method in which cable modems must time-share the upstream channel because there are
many cable modems and only one upstream channel frequency.
Transmission Control Protocol (TCP)
A method (protocol) used with the IP to send data in the form of message units (datagrams)
between network devices over a LAN or WAN. While IP handles the actual delivery of the data
(routing), TCP keeps track of the individual units of data (packets) that a message is divided
into for efficient delivery over the network. TCP requires the receiver of a packet to return an
acknowledgment of receipt to the sender of the packet.
Transmission Control Protocol/Internet Protocol (TCP/IP)
The basic communication language or set of protocols to communicate over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of protocols.
Trivial File Transfer Protocol
A file transfer protocol used to transfer automatically configuration or boot files.
Uniform Resource Identifier (URI)
A string of characters used to identify a name or a resource on the Internet.
Upstream
A term to describe the direction of data from the customer to the network service provider.
Uniform Resource Locator (URL)
A URI that specifies where a known resource is available and how to retrieve it.
