Paradyne 7112 manual EIA-232, Enterprise MIB, Enterprise-specific, Excessive BPV, Factory defaults

Glossary

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.
enterprise-specific	A trap unique to Paradyne devices.
trap
ES	Errored seconds. Seconds with one or more ESF error events.
ESF	Extended Superframe. The T1 transmission standard that specifies 24 frames as an
	extended superframe to be used for frame synchronization and to locate signaling bits.
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.
FDL	Facility Data Link. Selected bits in the ESF format that are used for control, monitoring,
	and testing.
FT1	Fractional T1. Individual DS0 channels that may be sold separately or in groups to provide
	bandwidth that is some fraction of the total T1 capability.
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.
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.
LAN	Local Area Network. A network designed to connect devices over short distances, like
	within a building.
LED	Light Emitting Diode. A status indicator that responds to the presence of a certain
	conditions.
link layer protocol	The protocol that regulates the communication between two network nodes.
LL	Local Loopback. An EIA-lead standard for V.24 circuit CT 141; an input signal
	(DTE-to-DCE).
LLB	Line Loopback. Loops the received signal on the network interface back to the network
	without change.
