Module
Module that provides power, GPS timing, and networking connections for an AP
cluster. Also known as CMM. If this CMM is connected to a Backhaul Module, then
this CMM is the central point of connectivity for the entire site.
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 values is 0 to 255. When set at 0, the Color Code does not
restrict communications with any other module.
Community String

about the module.
CPE Customer premises equipment.

recombination operations on blocks of data.
Desensed Received an undesired signal that was strong enough to make the module insensitive to
the desired signal.
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.
