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.
CIR Committed Information Rate. For an SM or specified group of
SMs, a level of bandwidth that can be guaranteed to never fall
below a specified minimum (unless oversubscribed). In the
Cambium implementation, this is controlled by the Low Priority
Uplink CIR, Low Priority Downlink CIR, High Priority Uplink CIR,
and High Priority Downlink CIR parameters.
CLIP Cassegrain Lens for Improved Performance
Cluster
Management
Module
Module that provides power, GPS timing, and networking
connections for an AP cluster. Also known as CMM.
CMM Cluster Management Module. A module that provides power, GPS
timing, and networking connections for an Access Point cluster.
CodePoint See DiffServ.
Color Code Field Module parameter that identifies the other modules with which
communication is allowed. The range of valid values is 0 to 255.
Community
String Field
Control string that allows a network management station to access
MIB information about the module.
Country Code A parameter that offers multiple fixed selections, each of which
automatically implements frequency band range restrictions for the
selected country. Units shipped to countries other than the United
States must be configured with the corresponding Region Code and
Country Code to comply with local regulatory requirements.
CRCError Field This field displays how many CRC errors occurred on the Ethernet
controller.
Data Encryption
Standard
Over-the-air link option that uses secret 56-bit keys and 8 parity
bits. Data Encryption Standard (DES) performs a series of bit
permutations, substitutions, and recombination operations on
blocks of data.
Demilitarized
Zone
Internet Protocol area outside of a firewall. Defined in RFC 2647.
