LIC
See library import characterization (LIC).
lift
The lifting device approved for use in installing modular components into a modular cabinet.
light-emitting diode (LED)
A semiconductor device that emits light from its surface. Indicator lights are composed of LEDs.
See also indicator lights.
line
The specific hardware path over which data is transmitted or received. A line can also have a
process name associated with it that identifies an input/output process (IOP) or logical device
associated with that specific hardware path.
line-handler process
See Expand line-handler process or Expand-over-ServerNet line-handler process.
line interface unit (LIU)
A dual-ported unit consisting of two parts: a communications line interface processor (CLIP) and a
line interface module (LIM). An LIU can communicate with either the primary or the backup processor,
providing fault tolerance. When it is a component of the communications subsystem, an LIU
communicates with either processor through either of a pair of communications interface units
(CIUs).
linear load
Electrical loads for which the impedance is constant regardless of the voltage, so that if the voltage
is sinusoidal, the current drawn is also sinusoidal.
link
In the Open System Services (OSS) file system, a directory entry for a file.
link count
In the Open System Services (OSS) file system, the number of directory entries that refer to a
particular file.
link name
In the Open System Services (OSS) environment, the filename associated with a specific file within
a directory. The length of a filename, and therefore the length of a link name, depends on the file
system.
link pulse
Indication that an Ethernet port is properly connected to an Ethernet.
linker
1. The process or server that invokes the message system to deliver a message to some other
process or server.
2. A programming utility, which combines one or more compilation units’ linkfiles to create an
executable loadfile for a native program or library.
