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
implementations of X.25 must use 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 LogicalChannel Identifier. Localvalue
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

Local Area Network Interface
Controller (LANIC) A hardware card
that fits into the backplane of the HP e3000
computer and provides a physical layer
interface for IEEE 802.3 local area
networks.
local connection See direct connection.
local node The computer that you are
configuring or that you are logged on to.
local switching A feature of the DTC
which permits back-to-back configuration
(for connections to an HP e3000 MPE/V
host), using two ports of the same DTC. See
also closed user group.
local user group A list defined for a
particular DTC and card that specifies
which remote nodes this DTC can send data
to and also which remote nodes this DTC
can receive data from.
logging The process of recording the usage
of network resources. Events can be logged
