At the end of the module, the participant will be able to:

Sketch a BSS Managed Object Hierarchy

Look up the parameters at each level, in the parameter dictionary

Identify parameter value ranges and default settings

Find the changes to objects and parameters, that occur with each BSS software release

Example from Parameter Dictionary

Parameter name Rxlev Access Min

Abbreviated name rxLevAccessMin

Managed object BTS

Multiplicity 1

Description With this parameter you define the minimum power level an MS has to receive before it is allowed to

access the cell.
