Glossary
J2 -
Wide-area digital transmission scheme used predominantly in Japan that carries data at a
rate of 6.312 Mbps.
Jitter -
analog communication line distortion caused by variations of a signal from its reference
timing position.
Joint Photographic Experts Group (JPEG) -
An ISO Standards group that defines how to com-
press still pictures.
Jumper -
a patch cable or wire used to establish a circuit, often temporarily, for testing or diag-
nostics; also, the devices, shorting blocks, used to connect adjacent exposed pins on a printed
circuit board that control the functionality of the card.
Kbps -
kilobits per second (thousand)
LAN Access Concentrator -
a LAN access device that allows a shared transmission medium to
accommodate more data sources than there are channels currently available within the trans-
mission medium.
LAN Emulation Address Resolution Protocol (LE_ARP) -
A message issued by a LE client to
solicit the ATM address of another function.
LAN Emulation Client (LEC) -
the component in an end system that performs data forwarding,
address resolution, and other control functions when communicating with other components
within an ELAN.
LAN Emulation Configuration Server (LECS) -
the LECS is responsible for the initial configura-
tion of LECs. It provides information about available ELANs that a LEC may join, together
with the addresses of the LES and BUS associated with each ELAN.
LAN Emulation Server (LES) -
the LES implements the control coordination function for an
ELAN by registering and resolving MAC addresses to ATM addresses.
LAN Emulation (LANE) -
technology that allows an ATM network to function as a LAN back-
bone. The ATM network must provide multicast and broadcast support, address mapping
(MAC-to-ATM), SVC management, and a usable packet format. LANE also defines Ethernet
and Token Ring ELANs.
lane -
a program that provides control over the execution of the LAN Emulation Server (LES),
Broadcast/Unknown Server (BUS), and LAN Emulation Configuration Server (LECS) on the
local host.
Latency -
The time interval between a network station seeking access to a transmission chan-
nel and that access being granted or received.
Layer Entity -
an active layer within an element.
Layer Function -
a part of the activity of the layer entities.
Layer Service -
a capability of a layer and the layers beneath it that is provided to the upper
layer entities at the boundary between that layer and the next higher layer.
