8.Is the number of cells received increasing?

•If no, go to step 6.

•If yes, continue.

9.Convert Allocated Bandwidth (kb/s) to cells (48 bytes). Bandwidth in cells = (1024 X Allocated Bandwidth) / 384 where 384 = 48 cells X 8

10.Is the Allocated Bandwidth less than the Cell Reception Rate?

•If no, go to step 6.

•If yes, this VC is misbehaving. Take appropriate action, for example, terminate the VC.
