TERM DEFINITION
Management Information Base
Management Information Base. A description of the data stored in a Network
Element similar to a C structure. A MIB definition allows the EDACS
Network Manager to read and write values in a Network Element.
MAU
Multistation Access Unit. A transceiver for LAN connections.
ME
Management Element. An EDACS platform that configures EDACS NEs.
Examples of MEs are CEC/IMC Manager, EDACS 4 Radio Programmer,
EDACS Network Manager, System Manager, PI terminal, EDG terminal, etc.
Media Access Control (MAC)
A protocol governing a station’s access to a network.
MIB
See Management Information Base.

Multiple Access Unit (MAU)
For a Token Ring, a concentrator used to connect multiple stations to the ring.
multisite
A
multisite
is a network of multiple EDACS radio systems and possibly
conventional radio systems all linked together for wide-area communication. In
a multisite network, adjacent systems do not use the same radio frequencies.
Each system networked may have a different number of working channels.
Native Proxy
Proxy that communicates with its agents via SNMP.
NE N
etwork
E
lement. An EDACS platform that provides links in the EDACS
network for either digital voice, analog voice, data, or control information. IT
IS NOT A PLATFORM USED TO CONFIGURE EDACS NEs. Examples of
NEs are IMC, GETC, Site Controllers, PIs, etc.
Network Address
The 32-bit IP address of a system.
Network Manager
The EDACS Network Manager is a UNIX workstation or server that provides
EDACS administrators with a consistent, integrated view of the alarm status of
their EDACS network.
Network Number
A network is a logical association of IMC, StarGate, CEC, and Remote CEC
nodes. The Network Number identifies the nodes for which the traffic will be
monitored by the Multisite Monitor.
