Term
Definition
DiffServ
Differentiated Services, consistent with RFC 2474. A byte in the type of service
(TOS) field of packets whose values correlates to the channel on which the
packet should be sent. The value is a numeric code point. Cambium modules
map each of 64 code points to values of 0 through 7. Three of these code points
have fixed values, and the remaining 61 are settable. Values of 0 through 3 map
to the low-priority channel; 4 through 7 to the high-priority channel. The
mappings are the same as 802.1p VLAN priorities. (However, configuring
DiffServ does not automatically enable the VLAN feature.) Among the settable
parameters, the values are set in the AP for all downlinks within the sector and
in the SM for each uplink.
Disable
To turn off a feature in the module after both the feature activation file has
activated the module to use the feature and the operator has enabled the feature
in the module. See also Activate and Enable.
DMZ
Demilitarized Zone as defined in RFC 2647. An Internet Protocol area outside
of a firewall. See http://www.faqs.org/rfcs/rfc2647.html.
Dynamic Host
Configuration
Protocol
See DHCP.
Electronic Serial
Number
Hardware address that the factory assigns to the module for identification in
the Data Link layer interface of the Open Systems Interconnection system.
This address serves as an electronic serial number. Same as MAC Address.
Enable
To turn on a feature in the module after the feature activation file has activated
the module to use the feature. See also Activate.
ESN
Electronic Serial Number. The hardware address that the factory assigns to the
module for identification in the Data Link layer interface of the Open Systems
Interconnection system. This address serves as an electronic serial number.
Same as MAC Address.
EthBusErr Field
This field displays how many Ethernet bus errors occurred on the Ethernet
controller.
Ethernet Protocol
Any of several IEEE standards that define the contents of frames that are
transferred from one network element to another through Ethernet
connections.
Fade Margin
The difference between strength of the received signal and the strength that the
receiver requires for maintaining a reliable link. A higher fade margin is
characteristic of a more reliable link. Standard operating margin.
FCC
Federal Communications Commission of the U.S.A.
Feature Activation
Key
Software key file whose file name includes the ESN of the target module. When
installed on the module, this file activates the module to have the feature enabled
or disabled in a separate operator action.
