This object defines the time duration of the data burst sent
over the air. The burst size is dependant on the capability of
the ODU which is represented by the cwrBurstSizeGroup variable
in the cwrRfTable.
The user must set this object based on the value of
cwrBurstSizeGroup in the cwrRfTable.
The approximate time duration for each of the burst sizes are:
small(1): 50 microseconds
medium(2): 100 microseconds
large(3): 200 microseconds
