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. The
PMP 450 AP’s support four levels of QoS. The mapping of these eight
priority values to data channels is determined by the number of data
channels configured per SM as shown in the table below:
For example, for an AP that uses the default table shown above has
configured 3 QoS levels per SM, would see codepoints 0 through 15
mapped to the Low Priority data channels, codepoint 16 would be
mapped to the Medium Priority data channels, and so on.
Note that CodePoints 0, 8, 16, 24, 32, 48, and 56 are predefined to the
fixed values shown in
Table 20 and are not user configurable. Operator
cannot change any of these fixed priority values. Among the
configurable parameters, the priority values (and therefore the handling
of packets in the high or low priority channel) are set in the AP/BHM for
all downlinks within the sector and in the SM/BHS for each uplink.
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 Frequency
Selection
A requirement in certain countries and regions for systems to detect
interference from other systems, notably radar systems, and to avoid
co-channel operation with these systems.
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.
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.
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.
