BackhaulModule
Also known as BH. A module that provides point-to-point connectivity
as either a standalone link or a link to an Access Point cluster through
a selected Access Point Module. See also Backhaul Timing Master
and Backhaul Timing Slave.
BackhaulTiming
Master
Backhaul Module that sends network timing (synchronization) to
another Backhaul Module, which serves as the Backhaul timing slave.
BackhaulTimingSlave
Backhaul Module that receives network timing (synchronization) from
another Backhaul Module, which serves as the Backhaul timing
master.
BAM
Bandwidth and Authentication Manager. A Cyclone software product
that operates on a Linux server to manage bandwidth, high-priority
channel, and VLAN settings individually for each registered Subscriber
Module. This software also provides secure Subscriber Module
authentication and user-specified encryption keys. The upgrade path
for this product is to Prizm Release 2.0 or later.
BER
Bit Error Rate. The ratio of incorrect data received to correct data
received.
BH
Backhaul Module. A module that provides point-to-point connectivity
as either a standalone link or a link to an Access Point cluster through
a selected Access Point Module.
BitErrorRate
Ratio of incorrect data received to correct data received.
BoxMIB
Management Information Base file that defines module-level objects.
See also Management Information Base.
BRAID
Stream cipher that the TIA (Telecommunications Industry Association)
has standardized. The secret keys in both modules communicate with
each other to establish the Data Encryption Standard key. See Data
Encryption Standard.
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.
Cyclone 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.
BridgeEntryTimeout
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.
