synchronization with its attached DTE or the remote modem; also used to describe a modem which converts
asynchronous inputs from the DTE to synchronous signals for modem-to-modem transmission.
B-1
TM 2000-OD/2C
Asynchronous Transfer Mode (ATM). A method of digitized data transmission based on fixed length cells. ATM
can carry multiple types of data text, voice, imagery, and video at high speeds.

begins to be transmitted is arbitrary. However, the time of occurrence of each signal representing a bit within the
character or block is predictable.
Attenuation. Deterioration of signals as they pass through a transmission medium; generally, attenuation increases
(signal level decreases) with both frequency and cable length. Measured in terms of levels or decibels.
Audio Frequency. A frequency which can be detected as a sound by the human ear. The range of audio frequencies
extends from approximately 20 to 20,000 hertz.
Authentication. A security measure designed to protect a communication system against fraudulent transmission.

establishing the authenticity of a transmission or message or of challenging the identity of a station.
Authenticator. A letter, numeral, or groups of letters or numerals, or both, attesting to the authenticity of a message
or transmission.
Backbone. The high traffic density connectivity portion of any communications network.
Band. A range of electromagnetic wave frequencies between definite limits, such as that assigned to a particular
type of radio service.
Bandwidth. The difference between the limiting frequencies of a continuous frequency band expressed in hertz
(cycles per second). The term bandwidth is also loosely used to refer to the rate at which data can be transmitted
over a given communications circuit. In the latter usage, bandwidth is usually expressed in either kilobits per
second (kbps) or Megabytes per second (Mbps).
Battery. An apparatus which may comprise a group of two or more cells used for the conversion of chemical energy
into electrical energy.
Battery Life. Approximate rating of how much energy a battery can deliver before its useful life is finished.
Baud. Measure of bandwidth. The higher the baud rate, the faster the data is transmitted.
Beacon. A light, group of lights, electronic apparatus or other device which emits identifying signals related to their
positions so that the information produced can be used for guidance orientation or warning.
Beacon, Radar. A radio navigation transponder which transmits in response to a specific received signal a, pulsed
radio signal with specific characteristics whereby the bearing and/or range of the transponder from the interrogator
may be determined, and which in some cases also be used to identify the transponder.
Beacon, Radio. A radio transmitter which emits a distinctive or characteristic signal used for the determination of
bearings, courses or location.
Binary. Digital system with 2 states, 1 and 0; contrast with octal, decimal and hexadecimal.
Bipolar Transmission. Method of sending binary data in which negative and positive states alternate; used in digital
transmission facilities such as DDS and T1. Sometimes known as polar transmission.
Bit. Contraction of binary digit; smallest unit of information and basic unit in digital data communications. A bit
can have a zero or a one value (a mark or space in data communications terminology).
B-2
TM 2000-OD/2C
Bit Concentration of “Binary Digit”. The smallest unit of measurement for computer data.
bps, bits per second. A measure of speed or data rate. Often combined with metric prefixes as in kbps for thousands
of bits per seconds (k for kilo-), in Mbps for millions of bits per second (M for mega-) and Gbps for billions of bits
per second (G for Giga-).
Breakout Box. A device that provides access for testing of circuits in a cable or connector.
Broadband. Communications channel having a bandwidth greater than a voice-grade channel and potentially
capable of much higher transmission rates; also called wideband.
Broadcast. Transmission of a message intended for general reception rather than for a specific station.
Buffer. A temporary storage device used to compensate for a difference in either the rate of data flow or the time of
occurrence of events in transmissions from one device to another.
Byte. A collection of bits operated upon as a unit; most are 8 bits long; and most character sets use one byte per
character. The capacity of storage devices is frequently given in bytes or in K bytes (K meaning 1024 bytes).
Cable-Based Local Area Network (LAN). A shared-medium LAN that uses a cable for its transmission medium.
Call Sign. Any combination of characters or pronounceable words which identifies a communication facility,
command, an authority, an activity, or a unit; used primarily for establishing and maintaining communications.
Call Sign, Tactical. A call sign which identifies a tactical command(s) or tactical communication facility(ies).
Carrier. A continuous signal which is modulated with a second, information-carrying signal.
Central Processing Unit (CPU). Actually the heart of a computer, but often used as a synonym for computer.
Challenge. Any process carried out by one unit or person with the objective of ascertaining the friendly or enemy
character or the identity of another. The answer to a challenge is a Reply.
Challenge and Reply. In authentication, a procedure by means of a prearranged system whereby one transmitter
requests authentication of another transmitter (the Challenge) and the latter by a proper reply establishes its
authentication (the Reply). In establishing identity, the challenge and the reply is a prearranged method whereby
one station identifies itself and requests the identity of another (the Challenge) and the latter identifies itself (the
Reply).
Channel. The smallest subdivision of a trunk, by means of which a single type of communications service is
provided; i.e., voice channel, teletypewriter channel, data channel.
Channel, (Frequency). Part of the frequency spectrum intended to be used for the transmission of signals and which
may be defined by two specified limits, or by its center frequency and the associated bandwidth, or by an equivalent
indication.
Channel, (Transmission). A transmission path suitable for a specific mode. A transmission channel may be
qualified by the nature of the transmitted signal, or by its bandwidth, or by its rare bit rate.
Cipher. Any cryptographic system in which arbitrary symbols or groups of symbols represent units of plain text of
regular length, usually single letters, or in which units of plain text are rearranged, or both, in accordance with
certain predetermined rules.
Circuit. The complete electrical path between end terminal instruments over which telecommunications are
provided.
B-3
TM 2000-OD/2C
Circuit Discipline. The component of transmission security which includes the proper use of communications
equipment, the adherence to the prescribed frequencies and operating procedure, remedial action, net control,
monitoring and training.
Circuit, Permanent. A circuit which is permanently provided and used in peacetime and which normally continues
to be used in wartime.
Circuit Restoration. The process by which a communications circuit supplier provides a circuit path between two
user stations after disruption or loss of the existing circuit path, in accordance with preplanned procedures and
priorities.
Circuit (Telecommunication). A telecommunication facility to transmit signals between message source and
message link by electric, electromagnetic, acoustic or visual means.

Clear. In plain text. When security of military information is not involved, messages are ordinarily sent in the clear
rather than in cipher or code.
Clear Text. Plain Language.
Client-Server Architecture. A computer networking architecture, client-server defines a software architecture and
not a hardware architecture. A client software entity (client) requests a service from a server software entity
(server), which in turn fulfills the request. To fulfill the request the server may provide data, perform processing
tasks, control a peripheral, or request the services of another server. A client can request services from multiple
servers and a server can service multiple clients. Because clients and servers are software entities, they can reside
on the same computer or be on different computers in a network. Servers are designated according to the services
provided. A server providing access to communications services would be called a communications server.
Clock. The timing signal used in synchronous transmission.
Closed Architecture. An architecture that is compatible only with hardware and software from a single vendor.
Contrast with open architecture.
Clutter. Collective term for unwanted echoes on a radar display.
Coax, Coaxial Cable. A transmission medium noted for its wide bandwidth and for its low susceptibility to
