LBRV - Low Bit Rate Voice - A voice sampling
technique that analyzes each 15-30 millisecond speech segment independently
and converts it into a 30-byte frame
LCC - Leadless Chip Carrier - A chip
package that uses flat metal pads that make contact with the socket
or circuit board
LCD - Liquid Cyrstal Display - the technology used for displays
in notebook and other small computers - allows displays to be thinner
than cathode ray tube technology - it consumes less power than LED
and gas display displays because they work on the principle of blocking
light rather than emitting it
LEC - Local Exchange Carrier - an authorized carrier that has been
commissioned to provide local voice-level telecommunication services
within a predetermined area
LED - Light Emitting Diode - adisplay
technology that uses a semiconductor diode that emits light when
charged. It is used in readouts and on/off lights in a myriad of
electronic appliances and as a light source for fiber-optic transmission.
They are typically used with lower-bandwidth multimode fibers.
LEO - Low Earth Orbit Satellite - Has global service, a 600 mile
orbit, is a non-geosynchronous orbit, has a 120 ms round-trip delay,
needs a minimum of 48 satellites to cover the globe
LMCC - Land Mobile Communications Council
- a trade group of frequency coordinators and associations serving
private users and commercial operators
LMDS - Local Multipoint Distribution Services - Fixed wireless transmission
technology that provides integrated, two-way digital distribution
of multimedia services using a combination of large, high-quality
bandwidth similar to fiber optic cable, yet delivered via a small
rooftop antenna. Works in the 28GHz range in the U.S. and 24-40GHz
overseas
LNP - Local Number Portability - a subscriber's ability to switch
local or wireless carriers and still retain the same phone number,
as is possible now with long distance carriers. Wireless carriers

LOD - Level of Detail LZW - Lempel-Zif-Welsh - a popular data compression
technology developed in 1977 - the compression algorithm used in
GIF graphics file format
LTO - Linear Tape Open - Family of open
magnetic tape standards developed by HP, IBM and Seagate that are
licensed to third-party vendors - has two formats that share common
components such as read/write head, track layout and servo technology.
The Accelis format uses a dual-hub, cassette-style cartridge with
a midpoint load very similar to Magstar MP. The Ultrium format uses
a single hub and a wider tape like regular Magstar
LU 6.2 - SNA protocol that establishes
a session between two programs. It allows peer-to-peer communications
as well as interaction between programs running in the host with
PCs, Macs and midrange computers
