The range is from 3 to 10.y size-The size of the step in milliseconds. The range is from 100 to 2000.A user is able to limit incoming calls in intervals of size time using call-admission spike command. Size and step make windows, the windows aremade by size intervals, and a size of a window would be size*step.The relationship between size and step is drawn in the figure below.Call-admission spike command is a command that limits incoming callsavailable in a window. Information on windows is created every size time, andwindows exist as many as steps.Figure 10.3 Call-admission spike window sizesizeWindow 1(step 5) Window 6(step 5)Window 2(step 5)Window 3(step 5)Window 4(step 5)Window 5(step 5)Call spike window size
