Summary:An apparatus for setting a communication path in ATM communication, comprises: communication path control unit for indicating a communication path test before starting communication; test cell assembling unit for assembling test cells that consist of a series of cells each of which has a sequential number for detecting test cell discard and has the higher cell discard priority (CLP=1); communication path setting unit for setting up the communication path and replacing transmit idle cells with the test cells; and cell-discard detecting unit for comparing the sequential number contained in received test cells with the number of the received test cells and thereby outputting a communication path setting enable or disable control signal.
