Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0
Allows communication from endstations directly to the device to
participate in LANE with ATM-connected devices.
Gives a LEC its configuration parameters at the beginning of LANE
participation. Also provides predefined values for all configuration
parameters.
Registers (learns) LANE-connected endstations. Also resolves MAC
addresses to ATM addresses.
Enables one vendor's implementation of LAN emulation to work
with another's. This specification is essential for building
multivendor ATM networks and is currently under development at
the ATM Forum.
Defines how legacy LAN applications and protocols work with ATM.
Currently in development at the ATM Forum, LUNI adapts layer 2
LAN packets to AAL 5 PDUs, which can then be divided into cells.
LUNI uses a client-server architecture to resolve LAN-to-ATM
addresses. A LAN Emulation Client (LEC) resides in each ATM-
attached device; a LAN Emulation Server (LES) and Broadcast and
Unknown Server (BUS) reside anywhere on the ATM network.
A point-to-point duplex cable connection between two ATM cell
switch ports. A link's ATM switch port is specified by its Avaya
system's IP host name and port number.
Establishes, configures, and tests the data-link connection.
The local protocol for publicizing the current network address of
available services.
A traffic parameter that specifies the maximum number of cells that
can be transmitted at ATM's Peak Cell Rate (PCR). Maximum burst
size is a key measurement in capacity planning and network
management.
A sublayer of the data link layer, as defined by the IEEE 802
committee, which defines frame format and media access
procedures for a particular type of LAN.
A database of information on managed objects in the Avaya system
unit that can be accessed via the SNMP network management
protocol.
