33) What do you call the value that represents a sensible cell load on which when the load is approaching this value, Traffic Handovers (TRHO) are performed?
  A. PRX_Target
  B. PRX_TARGET_BS
  C. SIR
  D. All of the choices
Ans: A

34) Since PRX_Target defines the planned load of the cell, maximum traffic admission is done up to this level in the cell.
  A. True
  B. False
  Ans: B
