Abstract:
A processing apparatus for measuring performance monitoring (PM) parameters concerning a reception signal received by a transmission device, the PM parameters being statistics of events that meet prescribed criteria for defects and anomalies, the processing apparatus comprising:a plurality of failure detecting means for detecting different kinds of failures in the reception signal and producing failure detection signals corresponding thereto, said plurality of failure detecting means including a first failure detecting means for detecting a first kind of failure and a second failure detecting means for detecting a second kind of failure;PM control means for detecting at least one kind of PM parameter, based on the failure detection signals produced by said plurality of failure detecting means;counting means for accumulating the PM parameter detected by said PM control means, said counting means operating at predetermined intervals to test whether the second kind of failure is present; andcontrol signal generating means for generating and supplying a stop command signal to said first failure detecting means to stop the detection of the first kind of failure, the stop command signal being activated during a period when the second kind of failure is present, asynchronously with the predetermined intervals at which said counting means tests the presence of the second kind of failure.
