Glossary

pmp-0049 (September 2012)
Term
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.
CarSenseLost Field
This field displays how many carrier sense lost errors occurred on the Ethernet
controller.
CAT 5 Cable
Cable that delivers Ethernet communications from module to module. Later
modules auto-sense whether this cable is wired in a straight-through or
crossover scheme.
