LANLocal Area Network
LANE LANEmulation. The alternate method of carrying network-layer packets across an ATM network, as opposed to native mode. The function of the LANE protocol is to emulate a local-area network on top of an ATM network. The LANE protocol defines a service interface for higher-layer (that is, network-layer) protocols that is identical to that of existing LANs, and that data sent across the ATM network is encapsulated in the appropriate LAN MAC format. The rationale for doing this is that it requires no modifications to higher-layer protocols to enable their operation over an ATM network.
LACPLink Aggregation Control Protocol is a 802.3ad IEEE standard that controls link aggregation forming of a single Ethernet link automatically from two or more Ethernet links.
LAGLink Aggregation Group
Last Gaspis feature that enables a device to store a small amount of power to enable it to send out a SNMP trap to alert a management station in the event of a power failure.
LATALocal Access and Transport Area. A telephone company term that defines a geographical area. (Normally, but not always, corresponds to an area code.)
Layer 3 SwitchingLayer 3 switching technology integrates routing with switching to yield very high routing throughput rates in the millions-of-packets-per-second range. The movement to Layer 3 switching is designed to address the downsides of the current generation of layer 2 switches, which are functionally equivalent to bridges. These downsides for a large, flat network include being subject to broadcast storms, spanning tree loops, and address limitations that drove the injection of routers into bridged networks in the late 1980s.

LECThe Local Exchange Carrier. The local telephone company for a given geographic area.
LEDLight Emitting Diode. A semiconductor device that emits light when voltage is applied.
Line HitsDrop outs, Phase hits, Gain hits, Impulse Noise
little-endianA format for storage or transmission of binary data in which the least significant byte (bit) comes first. See big-endian.
LLCLogical Link Control The upper portion of the datalink layer, as defined in IEEE 802.2. The LLC sub-layer presents a uniform interface to the user of the datalink service, usually the network layer. Beneath the LLC sublayer is the MAC sublayer.

LocalTalkLocal area network (LAN) protocol developed by Apple Computer. This network is designed to run over twisted pair wire and has a data rate of 235Kbps. All Macintosh computers contain a LocalTalk interface. See AppleTalk.
loopbackA diagnostic procedure where data is sent to the device being tested, and the output of the device is fed directly back to its input, looped around, and the returning data is checked against that which was sent.
LOWLightweight Directory Access Protocol. This protocol provides access for management and browser applications that provide read/write interactive access to the X.500 Directory.
LRCModems Longitudinal Redundancy Check Devices that modulate and demodulate
LOSLoss of signal
LTULine Terminating Unit. Terminates an E1 circuit. The functional equivalent of a CSU for a T1.
