PMP 450 Planning Guide Glossary
Term Definition
Logical Unit ID Final octet of the 4-octet IP address of the module.
LOS Line of sight. The wireless path (not simply visual path) direct from module to module.
The path that results provides both ideal aim and an ideal Fresnel zone.
LUID Logical Unit ID. The final octet of the 4-octet IP address of the module.
MAC Address Media Access Control address. 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.
Management
Information Base
Space that allows a program (agent) in the network to relay information to a network
monitor about the status of defined variables (objects).
Maximum
Information Rate
(MIR)
The cap applied to the bandwidth of an SM or specified group of SMs. In the Cambium
implementation, this is controlled by the Sustained Uplink Data Rate, Uplink Burst
Allocation, Sustained Downlink Data Rate, and Downlink Burst Allocation parameters.
Media Access
Control Address
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.
MIB Management Information Base. Space that allows a program (agent) in the network to
relay information to a network monitor about the status of defined variables (objects).
MIR See Maximum Information Rate.
NAT Network Address Translation defined in RFC 1631. A scheme that isolates Subscriber
Modules from the Internet. See http://www.faqs.org/rfcs/rfc1631.html .
NEC National Electrical Code. The set of national wiring standards that are enforced in the
U.S.A.
NetBIOS Protocol defined in RFC 1001 and RFC 1002 to support an applications programming
interface in TCP/IP. This interface allows a computer to transmit and receive data with
another host computer on the network. RFC 1001 defines the concepts and methods.
RFC 1002 defines the detailed specifications. See
http://www.faqs.org/rfcs/rfc1001.html and http://www.faqs.org/rfcs/rfc1002.html .
Network Address
Translation
Scheme that defines the Access Point Module as a proxy server to isolate registered
Subscriber Modules from the Internet. Defined in RFC 1631. See
http://www.faqs.org/rfcs/rfc1631.html .
Network
Management
Station
See NMS.
NMS Network Management Station. A monitor device that uses Simple Network
Management Protocol (SNMP) to control, gather, and report information about
predefined network variables (objects). See also Simple Network Management
Protocol.
