developing international
standards, including
communication standards.
L
LAN Local Area Network. A
collection of data communication
systems sharing a common cable
whereby each system can
communicate directly with
another
LAN address See station
address.
LANIC See Local Area
Network Interface Controller
LANIC physical path The
physical location (slot number) of
the LANIC within the SPU.
LANIC Self-Test A ROM-based
program on a LANIC card that
tests and reports the status of the
LANIC hardware.
LAP Link Access Protocol. The
data link protocol specified by
older versions (prior to 1980) of
X.25 at Level 2 but still permitted
and therefore usable. All new
implementationsof X.25 mustuse
LAP-B, and all old
implementations must migrate to
LAP-B at a future date.
LAP-B Link Access Protocol-
Balanced. The data link protocol
specified by the 1980 version of
X.25 at Level 2 that determines
the frame exchange procedures.
LAP-B must also be used over
direct-connect NS Point-to-Point
3000/iX Links.
LCI Logical Channel Identifier.
Local value on a network node
which identifies the channel used
to establish a virtual circuit (SVC
or PVC) through an X.25
network.
ldev See logical device
number.
leased line A data-grade
telephone line leased directly to a
subscriber and allocated
specifically for the subscriber’s
needs.
line speed The speed at which
data is transferred over a specific
physical link (usually measured
in bits or kilobits per second).
link name A name that
represents a hardware interface
card. The link name can contain
as many as eight characters. All
characters except the first can be
alphanumeric; the first character
must be alphabetic.
Local Area Network Interface
Controller (LANIC) A
hardware card that fits into the
backplane of the HP 3000
Series 900 computer andprovides
a physical layer interface for
IEEE 802.3 local area networks.
local connection See direct
connection.
