ACCULINK 316x DSU/CSU

LCD	Liquid Crystal Display. Sealed glass plates containing liquid crystal material. When
	voltage is applied, the amount of light passing through the plates is altered so that
	messages may be displayed.
LCP	Link Control Protocol.
LED	Light-Emitting Diode. A status indicator that glows in response to the application of
	a voltage.
link	A communication path between two network nodes.
link layer protocol	The protocol that regulates the communication between two network nodes.
link trap	A trap that identifies the condition of the communications interface (linkDown or
	linkUp traps).
LLB	Line Loopback. Loops the received signal on the network interface back to the
	network without change.
LOF	Loss Of Frame. The inability to maintain frame synchronization.
LOFC	Loss Of Frame Count. A count of the number of LOFs declared.
loopback test	A test that verifies a device's operation by connecting the device's output to the
	device's input.
LOS	Loss Of Signal. The T1 line condition where there are no pulses.
Lpbk branch	Local Loopback branch of the DSU/CSU menu tree.
LQR	Link Quality Reports.
manager (SNMP)	The device that queries agents for management information, or receives unsolicited
	messages (traps) indicating the occurrence of specific events.
master clock	The master timing source used to synchronize all of the T1 and data port interfaces
	on the DSU/CSU.
MB	Megabytes. A unit of memory measurement equal to approximately one million
	bytes (typically 1,048,576 bytes).
Mbps	Megabits per second (million bits per second).
menu tree	A display of DSU/CSU functions that are accessed by selecting various branches
	(Status, Test, etc.).
MIB	Management Information Base. A database of managed objects used by SNMP to
	provide network management information.
MIB II	MIB Release 2. The current Internet-standard MIB.
module	A compact assembly functioning as a component in a larger system or unit.
MRU	Maximum Request Unit.
multiplex	To interleave or simultaneously transmit two or more messages on a single circuit.
network	A configuration of data processing devices for information exchange.
network interface	The T1 network interface connector on the rear panel of the DSU/CSU.
NMS	Network Management System. A computer system used for monitoring and
	controlling network devices.
node	A connection or switching point on the network.
object (SNMP)	A specific item within a Management Information Base (MIB).
OOF	Out Of Frame. An error condition in which frame synchronization bits are in error.
option	A hardware or software function that can be selected or enabled as part of a
	configuration process.
