ABSTRACT:
A BRM changing circuit 4 that changes congestion information of a BRM cell is disposed on the output side of a down line (from the network side to the user side) of a cell rate supervising apparatus. The BRM changing circuit 4 places an ACR value calculated by an ACR calculating circuit 3 with congestion information (a CI bit, an NI bit, and an ER area) in a BRM cell received from the network through the down line to the ER area of the BRM cell. The resultant BRM cell that has been changed by the BRM changing circuit 4 is sent to the user side terminal unit through the down line.
