Definition
APs MIB Management Information Base file that defines objects that are
specific to the Access Point Module. See also Management
Information Base.
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.
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 an SM, the SM 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.
Carrier-to-
interference
Ratio
Ratio of intended reception to unintended reception.
