CMM
Cluster Management Module. A module that provides power, GPS timing, and
networking connections for an Access Point cluster. If this CMM is connected to a
Backhaul Module (BH), then this CMM is the central point of connectivity for the entire
site.
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.
Committed
Information Rate
(CIR)
For an SM or specified group of SMs, a level of bandwidth that can be guaranteed to
never fall below a specified minimum. In the Motorola implementation, this is controlled
by the Low Priority Uplink CIR, Low Priority Downlink CIR, High Priority Uplink
CIR, and High Priority Downlink CIR parameters.
Community
String Field
Control string that allows a network management station to access MIB information
about the module.
CPE
Customer premises equipment.
CRCError Field
This field displays how many CRC errors occurred on the Ethernet controller.
CRM
Customer relationship management system.
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.
Date of Last
Transaction
A field in the data that the cmd show esn command generates from data in the SQL
database in the Bandwidth and Authentication Manager (BAM) server. This field
identifies the date of the most recent authentication attempt by the SM. Expressed in the
database output as DLT.
Dell
A trademark of Dell, Inc.
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.
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.
