Attenuation to Card

Glossary-2

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 provides 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 an SNMP manageable

device to determine whether 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 Systems equipment to provide connections to external

networks through an integrated bridge or router.

Broadcast A type of network transmission; a broadcast transmission is one which is

sent to every station on the network, regardless of location, identiﬁcation,

or address.

Buses Physical portions of the backplane of a modular chassis which pass

information between modules.

Card See Module.
