Glossary

DCE	Data Communications Equipment. The equipment that provides the functions required to
	establish, maintain, and end a connection. It also provides the signal conversion required
	for communication between the DTE and the network.
DDS	Digital Data Service. Provides digital communication circuits.
DMI	Data Mode Idle. Refers to a sequence of ones transmitted or received on the DDS
	network.
DSR	Data Set Ready. An EIA-lead standard for V.24 circuit CT 107; an output signal
	(DCE-to-DTE).
DSU	Data Service Unit. Data communications equipment that provides an interface between the
	DTE and the digital network.
DTE	Data Terminal Equipment. The equipment, such as computers and printers, that provides
	or creates data.
DTR	Data Terminal Ready. An EIA-lead standard for V.24 circuit CT 108; an input signal
	(DTE-to-DCE).
EIA	Electronic Industries Association. This organization provides standards for the data
	communications industry to ensure uniformity of interface between DTEs and DCEs.
EIA-232	The EIA's standards defining the 25-pin interface between the DTE and DCE.
Enterprise MIB	MIB objects unique to Paradyne devices.
excessive BPV	An excessive bipolar violation condition results when at least one invalid bipolar violation
	has occurred every 20 milliseconds for 2 seconds.
factory defaults	A predetermined set of configuration options for general operation.
FCC	Federal Communications Commission. Board of Commissioners that regulates all U.S.
	interstate, intrastate, and foreign electrical communication systems that originate from the
	United States.
frame relay	A switching interface that is designed to get frames from one part of the network to another
	as quickly as possible.
full-duplex	The capability to transmit in two directions simultaneously.
HDLC	High-Level Data Link Control. A communications protocol defined by the International
	Standards Organization (ISO).
ICMP	Internet Control Management Protocol. Internet protocol that allows for the generation of
	error messages, tests packets, and information messages related to IP.
IMC	In-band Management Channel. A proprietary TDM channel used for IP connectivity.
interface	A shared boundary between functional units.
IP	Internet Protocol. The TCP/IP standard protocol that defines the unit of information passed
	across an Internet and provides the basis for packet delivery service. IP includes the ICMP
	control and error message protocol as an integral part. The entire protocol suite is often
	referred to as TCP/IP because TCP and IP are the two most fundamental protocols.
IP address	The IP address has a host component and a network component. The address is assigned
	to hosts or workstations with direct Internet access to uniquely identify entities on the
	Internet.
ITU	International Telecommunication Union, formerly known as CCITT . An advisory committee
	established by the United Nations to recommend communications standards and policies.
LADS	Local Area Data Set is used to provide a point-to-point link between two devices (also
	called LDM ± limited distance modem).
