Glossary

BES	Bursty Error Seconds. A second in which more than one but less than 320 CRC6 error
	events have occurred.
bipolar signal	A signal in which successive ones (marks, pulses) are of alternating positive and negative
	polarity, and in which a zero (space, no pulse) is of zero amplitude.
bit	Binary digit. The smallest unit of information, representing a choice between a one or a
	zero (sometimes called mark or space).
bps	Bits per second. Indicates the speed at which bits are transmitted across a data
	connection.
BPV	Bipolar Violation. In a bipolar signal, a one (mark, pulse) which has the same polarity as its
	predecessor.
byte	A sequence of successive bits (usually eight) handled as a unit in data transmission.
CCITT	Consultative Committee on International Telegraphy and Telephony. An advisory
	committee established by the United Nations to recommend communications standards
	and policies. It was renamed ITU in March 1993.
CD	Carrier Detect. The received line signal detector. V.24 circuit 109.
channel	A bidirectional DS0, voice, or data path, for electrical transmission between two or more
	points. Also called a circuit, line, link, path, or facility.
CHAP	Challenge Handshake Authentication Protocol. A security technique that allows a user
	password to be encrypted for transmission.
character	A letter, figure, number, punctuation, or other symbol.
client	A device that receives a specific service, such as database management, from a server.
coding	A technique used to accommodate the ones density requirements of E1 lines.
community name	An identification used by an SNMP manager to grant an SNMP server access rights to a
	MIB.
COMSPHERE	A proprietary product family name and a registered trademark of Paradyne.
configuration	The arrangement of a system or network as defined by the characteristics of its functional
	units.
configuration option	Device software that sets specific operating parameters for the device. Sometimes
	referred to as straps.
CPU fail	Central Processing Unit failure. A Self-Test Health message indicating a failure in the
	device’s central processing unit.
CRC	Cyclic Redundancy Check. A mathematical method of confirming the integrity of received
	digital data.
CRC6	CRC using six check bits.
CSA	Canadian Standards Association.
CSU	Channel Service Unit. A device that connects service user equipment such as a DSU to
	the local digital telephone loop, protects the line from damage, and regenerates the signal.
CTS	Clear To Send. A signal indicating that the device is ready for the DTE to transmit data.
	Usually occurs in response to Request To Send (RTS).
D4	The transmission standard that specifies 12 frames as a superframe that is used for frame
	synchronization and to locate signaling bits.
database	An organized compilation of computerized data.
