Attenuation to BRIM
GL - 2 EMM-E6 User’s Guide
Attenuation Loss of signal power (measured in decibels) due to
transmission through a cable. Attenuation is dependent on
the type, manufacture and installation quality of cabling,
and is expressed in units of loss per length, most often
dB/m.
AUI Attachment Unit Interface. A cabling type used in Ethernet
networks, designed to connect network stations and
devices to transceivers.
Backbone A portion of a network which provides the interconnection
of a number of separate, smaller networks.
Backplane The portion of a modular chassis to which all modules
are connected. Typically the backplane provide power and
management functions to each module, and is used to
provide networking connections, via buses, to all modules
in the modular chassis.
Bit Binary Digit. A bit is the smallest unit of information,
consisting of a single binary number. A bit is represented
by a numerical value of 1 or 0.
BOOTP Bootstrap Protocol. Checks MIB variables of a SNMP
manageable device to determine to determine wether it
should start up using its existing firmware or boot up from
a network server specifically configured for the purpose.
Branch Group A collection of MIBs related by common function. These
MIBs are collected into families called branches. See also
Leaf Object, MIB Tree.
Bridge Bridges are network devices which connect two or more
separate network segments while allowing traffic to be
passed between the separate networks when necessary.
Bridges read in packets and decide to either retransmit
them or block them based on the destination to which the
packets are addressed.
BRIM Bridge/Router Interface Module. BRIMs are added to
BRIM-capable Cabletron equipment to provide
connections to external networks through an integrated
bridge or router.
