10BaseT Unshielded, twisted pair cable with an RJ-45 connector used with an Ethernet
LAN. “10” indicates the speed: 10Mbps; “Base” means that it is baseband
technology; and “T” means that it is a twisted pair cable.
16 QAM Modulation scheme used by a modem transmitter. QAM uses amplitude and
phase modulation to encode multiple bits of data in one signaling element, thus
achieving higher data transfer rates than amplitude or phase modulation alone.
16 QAM encodes four bits per symbol as one of sixteen amplitude and phase
combinations. 16 QAM refers to the number of discrete phase/amplitude states
that represent data bits.
64 QAM A modulation scheme used by a cable modem receiver. 64 QAM uses
amplitude and phase modulation to encode multiple bits of data in one
signaling element. 64 QAM encodes 6 bits per symbol as one of 64 amplitude
and phase combinations.
256 QAM A modulation scheme used by a cable modem receiver. 256 QAM uses
amplitude and phase modulation to encode multiple bits of data in one
signaling element. 256 QAM encodes 8 bits per symbol as one of 256 possible
amplitude and phase combinations.
bandwidth The range of frequencies that can be passed over a channel.
bridge A device used to connect two LANs that use similar LAN protocols. The
bridge acts as an address filter, picking up packets from one LAN that are
intended for a destination on another LAN and passing them on. The bridge
does not modify the contents of a packet and does not add anything to the
packet. The bridge operates at Layer 2 of the Open System Interconnect (OSI)
model.
broadband Network technology that multiplexes multiple, independent network carriers
onto a single cable. The technology is used to carry voice, video, and data over
a cable.
broadcast Transmission to two or more devices at the same time, such as over network or
by satellite; protocol mechanism by which group and universal addressing is
supported.
Cable Modem
Termination System
(CMTS)
A device located in the cable system headend that interfaces the hybrid
fiber/coaxial (HFC) network to local or remote Internet Protocol (IP) networks.
Motorola’s CMTS (Cable Router) provides connections between IP hosts and
cable modems, and between the cable modems and the connected subscribers.
It also manages cable modem bandwidth.
coaxial cable (coax) Cable that consists of an inner conductor surrounded by insulation. An outer
conductor is wrapped around the insulation, which is typically covered by
plastic. Coaxial cable has large bandwidth and can support transmission over
long distances.
Glossary-2
communication network A facility that provides a data transfer service among the equipment attached to
a network.
Customer Premise
Equipment (CPE)
Equipment at the end user premises. This equipment may be provided by the
end user or service provider.
DOCSIS The Data-Over-Cable Service Interface Specifications.
downstream The direction of data flow from a CMTS to a cable modem.
Dynamic Host
Configuration Protocol
(DHCP)
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.
encryption A method of encoding data.
encryption key A key that is used to encrypt data to deter unauthorized interception.
Ethernet A networking standard running at speeds of 10 Mbps (10BaseT) or 100 Mbps
(100BaseT).
Ethernet address The physical address of the Ethernet port. It is also known as a MAC address or
a NIC address.
Ethernet card 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).
event A message generated by a cable modem to inform an operator that something
has occurred.
F connector Connector on a cable modem that connects it to the cable system.
File Transfer Protocol
(FTP)
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.
firewall 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.
Forward Error
Correction (FEC)
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.
headend The central office of the service provider where cable signals originate.
Home Phone Networking
Alliance (HPNA)
Industry organization that defines a set of standards for home phoneline
networking technologies (www.homephna.org).
Glossary-3
hub A device used to connect multiple devices to a LAN or similar structure to a
headend.
Hybrid Fiber/Coaxial
(HFC) network
A network where the trunk of the cable plant is fiber technology. The fiber is
connected to a coaxial cable and the signal is converted so that it is compatible
to that media. The coaxial cable runs through the branches of the network and
is dropped into the subscriber’s home.
Initial Maintenance (IM) A contention interval that provides an opportunity for modems to join a
network.
Internet A collection of interconnected networks used for world-wide communications.
These networks use the TCP/IP protocol.
IP address A 32-bit address assigned to every device in a network. An IP address has two
parts: a network address and a host address. Each network is assigned an
address by a governing agency, and each company administrator assigns an
address to each host. Network addresses can be 8, 16, or 24 bits long
corresponding to classes A, B, and C, respectively, with the host address
occupying the remainder of the 32 bits. If a service provider uses Class C
addresses, for example, the first 24 bits are the network address and 8 bits are
used for host addresses.
An IP network address can be further divided by using classless addressing or
subnetting. See subnet.
IP filtering IP filtering allows IP packets to be dropped according to information in the
packet, such as its source or destination address. IP filtering can prevent
subscribers from accessing headend servers, enforce subscribers to log on to
the cable network, enforce separately-billed service packages for data, and
provide group access control for IP Multicast.
IP network A group of IP routers that route IP datagrams. These routers are sometimes
referred to as internet gateways. Single users access the IP network from a host.
Each individual network in the Internet includes some combination of hosts
and IP routers.
Local Area Network
(LAN)
A privately owned and administered network for data communications. A LAN
provides a relatively high bandwidth over a limited geographical area for
communication among the attached devices, typically personal computers and
servers. Communication is usually accomplished by broadcasting on a
connectionless basis over a shared media.
MAC Layer Domain A collection of upstream and downstream channels for which a single Media
Access Control (MAC) Allocation and Management Protocol operates. Its
attachments include one CMTS and a number of cable modems.
Maximum Transmission
Unit (MTU)
The largest amount of data that can be transmitted in one discrete message on a
physical network. MTUs can be user configurable.
Mbps Mega (million) bits per second. A rate of data transfer.
Glossary-4
Media Access Control
Address (MAC)
The hardware address usually “burned in” on a ROM for any device connected
to the network. Ethernet cards in the subscriber PC have a MAC address. The
cable modem and the network interface card on a CMTS have MAC addresses.
The MAC address is used by the link layer protocol to forward packets “one
hop at a time” between the host and the first router and between the first router
and the next router and so on through the network until the packet arrives at its
final destination. In contrast, an IP address is a “source” to “destination”
address. It does not include all the intermediate hops.
Media Access Control
(MAC) sublayer
The part of the data link layer that supports topology-dependent functions and
uses the services of the physical layer to provide services to the logical link
control (LLC) sublayer.
MHz Mega Hertz. A measure of radio frequency - millions of cycles per second.
modem registration The process by which a cable modem makes itself known to a CMTS. The
modem configuration and authorization are verified and the COS is negotiated.
network driver A file packaged with the Ethernet card that connects the card to the PC
communications software.
network layer Layer 3 in the Open System Interconnection (OSI) architecture. This layer
provides services to establish a path between open systems.
packet data Each IP datagram consists of one or more packets. A packet has a header that
contains the source address and a destination address for routing (and other
housekeeping information). Since both the header and the data area can vary in
length, an IP datagram itself is variable in length.
PING A program that tests host reachability by using the Internet Control Message
Protocol (ICMP) echo request and waiting for a reply. It is initiated and
verified from an IP device.
physical layer (PHY) Layer 1 in the Open System Interconnection (OSI) architecture. It is the layer
that provides services to transmit bits or groups of bits over a transmission link
between open systems. It includes the electrical, mechanical, and handshaking
procedures.
Physical Media
Dependent (PMD)
Sublayer
A sublayer of the physical layer that transmits bits or groups of bits over
particular types of transmission links between open systems. It entails the
electrical, mechanical, and handshaking procedures.
piggybacking A process that occurs when a modem transmits data and requests additional
bandwidth at the same time.
Quadrature Amplitude
Modulation (QAM)
Modulation scheme that uses both amplitude and phase modulation to encode
multiple bits of data in one signaling element, thus achieving higher data
transfer rates than just amplitude or phase modulation alone.
However, the signal is more prone to errors caused by noise and so requires a
better quality transmission circuit than QPSK (lower noise and therefore higher
Carrier to Noise Ratio (CNR) value).
Glossary-5
Quadrature Phase Shift
Key (QPSK)
Modulation that sends two bits of information per symbol period with one bit
90 degrees out of phase with the other bit being sent. There are only four
constellation points. These points represent the four combinations that can take
place and are represented by the coordinates:
(0,0 - 0,1 - 1,0 - 1,1).
DQPSK modulation states that the information bits are differentially encoded
prior to being modulated.
quality of service The accumulation of the cell loss, delay, and delay variation incurred by cells
belonging to a connection.
radio frequency (RF) Signals that are used by a cable modem transmitter and receiver to send data
over the HFC network. A radio frequency carrier is modulated to encode the
digital data stream for transmission across the cable network.
return loss A measurement of the quality of the match of the device to the cable system.
Return loss is the ratio of the amount of power reflected by the device.
RJ-45 An 8-pin modular connector on a Motorola cable modem or CMTS that
connects the modem to a PC or external hub. Used as a 10BaseT or 100BaseT
standard connector.
router A device used to connect two subnetworks at the network layer. These
subnetworks may be similar. An internet protocol is used in each router and in
each host of the network. A router operates at Layer 3 of the OSI model.
service provider A company providing cable data services to subscribers.
splitter A piece of coax equipment that divides a single spectrum into multiple
identical spectrums.
TCP/IP A set of protocols that provides the standards and rules for controlling and
managing communications between networks. TCP/IP has become the
worldwide standard for internetworking and is the basis for the worldwide
Internet. TCP/IP stands for Transmission Control Protocol/Internet Protocol.
There are related protocols, services, and applications that are part of the
TCP/IP protocol suite.
TCP/IP Communications
Stack
Software in the subscriber PC that processes packets through the
communication layers. The TCP/IP communication stack handles the
communications between the subscriber’s application, for example, an Internet
browser, and servers on the Internet.
Transmission Control
Protocol (TCP)
A reliable transport protocol of the Internet suite. TCP is a connection-oriented
protocol that uses IP to transmit the data across the network. TCP is an
end-to-end protocol defining the rules and procedures for exchanging
information between communicating partners (hosts). Transmission Control
Protocol resides in the Transport Layer of the OSI stack. It works on top of
connectionless Network Layer IP. TCP segments messages into datagrams,
uses a timer to keep track of outstanding datagrams, retransmits datagrams if
requested, and performs error checking on incoming datagrams.
Universal Serial Bus
(USB)
A device that allows PCs to connect to peripherals, eliminating the need for an
Ethernet Card.
