Term
Definition
ARP
Address Resolution Protocol. A protocol defined in RFC 826 to
allow a network element to correlate a host IP address to the
Ethernet address of the host. See
http://www.faqs.org/rfcs/rfc826.html
ASN.1
Abstract Syntax Notation One language. The format of the text files
that compose the Management Information Base.
Attenuation
Reduction of signal strength caused by the travel from the
transmitter to the receiver, and caused by any object between. In
the absence of objects between, a signal that has a short
wavelength experiences a high degree of attenuation nevertheless.
BER
Bit Error Rate. The ratio of incorrect data received to correct data
received.
BHM
BHM (Backhaul Master) - a module that is used in a point to point
link. This module controls the air protocol and configurations for
the link.
BHS
BHM (Backhaul Slave) - a module that is used in a point to point
link. This module accepts configuration and timing from the master
module.
Bit Error Rate
Ratio of incorrect data received to correct data received.
Box MIB
Management Information Base file that defines module-level
objects. See also Management Information Base.
Bridge
Network element that uses the physical address (not the logical
address) of another to pass data. The bridge passes the data to
either the destination address, if found in the simple routing table,
or to all network segments other than the one that transmitted the
data. Modules are Layer 2 bridges except that, where NAT is
enabled for a BHS, the BHS is a Layer 3 switch. Compare to Switch
and Router, and see also NAT.
Bridge Entry
Timeout Field
Value that the operator sets as the maximum interval for no activity
with another module, whose MAC address is the Bridge Entry. This
interval should be longer than the ARP (Address Resolution
Protocol) cache timeout of the router that feeds the network.
Buckets
Theoretical data repositories that can be filled at preset rates or
emptied when preset conditions are experienced, such as when
data is transferred.
Burst
Preset amount limit of data that may be continuously transferred.
C/I Ratio
Ratio of intended signal (carrier) to unintended signal
(interference) received.
