Usage parameter control circuit.

摘要

A usage parameter control circuit for effecting a policing control in an ATM transmission network, comprising a time interval measuring unit (10) for measuring a time interval between a currently arrival time of a cell to be judged, and an arrival time of a cell which arrived a reference threshold number (X) of cells before the currently arriving cell arrives; and a judging unit (20) for judging whether or not the measured time interval is shorter than a reference threshold time interval (T), whereby a longer accessing time is allowed and the circuit construction has a flexible expandability.
