| LDS I |
An LXE proprietary protocol that has asynchronous
data streams with ASCII encoded characters.
|
| LDS II |
An LXE proprietary protocol that uses asynchronous
framing techniques with ANSI encoded characters.
|
| Legacy equipment |
A term used at LXE, interchangeably, to indicate
existing LXE manufactured equipment.
|
| Lemo connector |
A type of serial electronic connector used on LXE
terminals. |
| light emitting diode (LED) |
A diode that lights up when a voltage is applied to
it. This diode is made of a substance that illuminates when electricity passes
through it.
|
| line truncation |
A technique that allows the screen to display only
the portion of a line that fits within the actual display area of the terminal.
|
| Link Access Procedure (Balanced) [LAP-B] |
The most common data link control protocol used to
interface X.25 DTEs with X.25 DCEs. X.25 also specifies a LAP, or Link Access Procedure
(not balanced). Both LAP and LAP-B are full-duplex, point-to-point
bit-synchronous protocols. The unit of data transmission is called a frame;
frames may contain one or more X.25 packets. |
| link layer |
A set of counters within the LXE network controller
that provides statistics on message activity between the network controller and
the host. |
| Link State Protocol
(LSP) |
Any routing protocol that recognizes speed,
reliability and other functional characteristics of the communications link.
(Novell)
|
| Link Support Layer
(LSL) |
A layer within the Novell ODI driver specification
which allows multiple protocol stacks to access a network card simultaneously.
|
| Liquid Crystal Display (LCD) |
A display device with a liquid crystal sealed
between two glass plates.
|
| lithium ion battery (Li-Ion) |
Lithium-Ion (Li-Ion) is the latest technology
available for rechargeable batteries. In comparison to conventional nickel
cadmium (NiCd) batteries, Li-Ion batteries have a higher charge capacity in a
smaller and lighter weight package. As a result, they will power devices longer
than comparable NiCd or nickel metal hydride (NiMH) batteries. Since
lithium-ion batteries do not suffer from a "memory effect", it is not
necessary to fully discharge them to retain their full capacity. |
| load, loading |
-
A system for adding regularly spaced inductance
units to a circuit to improve its transmission characteristics.
-
The process of copying a file across a network
directly into the user system's memory and running that program.
|
| Local Area Network (LAN) |
A network of computers and peripherals that spans a
small physical area. |
| Local Area Transport (LAT) |
Digital Equipment Corporation's protocol for
communication on a Local Area Network (LAN)
|
| Local Field Edit |
A 3270, 5250, and ANSI terminal software feature
that allows the host application program to control the type of data the user
enters. |
| Logical Unit (LU) |
-
A software element within an IBM SNA/SDLC
network that provides end users with access to the communication system.
-
A program that uses the network.
-
An LXE 3270 terminal is called a Physical Unit
(PU) or LU and the application, too, is called the Logical Unit.
|
| LU Termself |
A synchronous network architecture (SNA) command
that controls whether the network controller sends a standard command to the
host, or whether the network controller sends a "power-off LUSTAT" to
the host.
|
| LXE Data Stream (LDS) |
An LXE proprietary networking protocol.
|
| LXE Inc. |
LXE is a subsidiary of Electromagnetic Sciences
(EMS) which includes CAL Corporation. EMS focuses on deep space communications
and complex antenna arrays while CAL focuses on GPS, search and rescue and
vehicle tracking. The shared RF technology of the EMS family allows LXE to draw
on RF experience and expertise that is unmatched by any competitor.
In 1972, LXE delivered its first radio-linked
terminal system. Since then, many generations of LXE terminal systems have been
developed and sold to a variety of industries. The depth of RF experience,
products, and service has made LXE a world leader in supplying radio-linked
data communications systems.
|
| LXE Network Management Workstation |
Abbreviated as either NMS or LXE-NMWS. Network
Management Station (NMS) is the industry standard term for an SNMP management
station. LXE's 6200 System network management program refers to the workstation
running the software as the LXE Network Management WorkStation (LXE-NMWS).
The LXE-NMWS is a desktop computer that contains
network management software applications and functions as the network host
computer. These computers tend to be high powered workstations with a graphical
user interface frontend. They are configured with the appropriate hardware to
gather network status details, analyze data and display network information.
They may also be designed to set up LXE RFN, NC and RFU configurations.
