Electronic Industries Association. This organization provides standards for the data

communications industry to ensure uniformity of interface between DTEs and DCEs.

The EIA’s standards defining the 25-pin interface between the DTE and DCE.

MIB objects unique to Paradyne devices.

A trap unique to Paradyne devices.

Errored seconds. Seconds with one or more ESF error events.

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.

An excessive bipolar violation condition results when at least one invalid bipolar violation

has occurred every 20 milliseconds for 2 seconds.

A predetermined set of configuration options for general operation.

Federal Communications Commission. Board of Commissioners that regulates all U.S.

interstate, intrastate, and foreign electrical communication systems that originate from the

United States.

Facility Data Link. Selected bits in the ESF format that are used for control, monitoring,

and testing.

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.

The capability to transmit in two directions simultaneously.

High-Level Data Link Control. A communications protocol defined by the International

Standards Organization (ISO).

Internet Control Management Protocol. Internet protocol that allows for the generation of

error messages, tests packets, and information messages related to IP.

A shared boundary between functional units.

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.

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.

International Telecommunication Union, formerly known as CCITT. An advisory committee

established by the United Nations to recommend communications standards and policies.

Local Area Network. A network designed to connect devices over short distances, like

within a building.

Light Emitting Diode. A status indicator that responds to the presence of a certain

conditions.

The protocol that regulates the communication between two network nodes.

Local Loopback. An EIA-lead standard for V.24 circuit CT 141; an input signal

(DTE-to-DCE).

Line Loopback. Loops the received signal on the network interface back to the network

without change.
