MIB Management Informaon Base is a virtual database used for managing the objects
(parameters) in a communicaons network. Most oen associated with the Simple
Network Management Protocol (SNMP). The MIB database is hierarchical (tree-
structured). The soware that performs the navigaon in the MIB database is a
MIB browser. The MIB database is Jotron proprietary and contains descripons and
definions for all parameters in the radio. The MIB database is updated each me a
new radio parameter is added or changed.
