Abstract

A police system of ATM exchange comprises an ATM exchange for exchanging the ATM cells, and an input cell speed limiting unit disposed in an input side of the ATM exchange and having a plurality of elastic buffers with a read speed equivalent to a band designated to each of a plurality of subscribers accommodated in the exchange, the elastic buffers being in accordance with the subscribers, the input cell speed limiting unit being arranged to limit the speeds of cells which are transmitted from each of the subscribers to the exchange to the band designated to each of the subscriber. The ATM exchange can completely manage and restrict the band of a line. Even if a congestion state takes place instantaneously due to an excessive cell flow, it does not affect calls which are in compliance with a predetermined band.
