Cluster Management
Module
Module that provides power, GPS timing, and networking
connections for an AP cluster. Also known as CMM4.
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.
Connectorized
The 450 Platform Family Connectorized Radio solution provide RF
port to connect external antenna. It gives flexibility to connect to a
variety of external antennas.
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. See
http://www.faqs.org/rfcs/rfc2647.html.
DES
Data Encryption Standard. An over-the-air link option that uses
secret 56-bit keys and 8 parity bits. DES performs a series of bit
permutations, substitutions, and recombination operations on
blocks of data.
DFS
See Dynamic Frequency Selection
DHCP
Dynamic Host Configuration Protocol, defined in RFC 2131. Protocol
that enables a device to be assigned a new IP address and TCP/IP
parameters, including a default gateway, whenever the device
reboots. Thus DHCP reduces configuration time, conserves IP
addresses, and allows modules to be moved to a different network
within the system. See http://www.faqs.org/rfcs/rfc2131.html. See
also Static IP Address Assignment.
