In a packet communication network in which a plurality of subscriber's lines are connected with a packet switching unit via a multiplexer and each of terminal units declares the packet rate on call request, a packet rate monitoring circuit is provided between the packet switching unit and the multiplexer. The packet rate monitoring circuit includes a circuit for monitoring the cell arrival rate, a circuit for detecting a packet cell violating the declared value which is transmitted from the terminal, a circuit for adding a mark representative of the violation cell to the violation packet which is detected by the detecting circuit, and a circuit for automatically modifying the declared parameter. The modifying circuit applies the declare parameter which was automatically modified in accordance with utilization condition (the number of multiplexings and the line utilization) of the multiplexer disposed between the subscriber's terminals and the rate monitoring circuit so that the detecting circuit detects the violation packets based upon the modified declared parameter.
