Abstract:
1. An operational status testing apparatus for an APS process performed in a processor of a first node for interchanging path status information and a protection switching command with an APS process of a second node which is connected to the first node via an Ethernet network, the apparatus comprising: an APS processing unit operating the APS process of the first node in the processor of the first node; a received signal filtering unit filtering a test command signal which contains a command to perform an operational test for the APS process of the first node and filtering a second test response signal that indicates that the operation of the APS process of the second node is performed normally, from among far end request signals that are received from the second node and when the far end request signals are test command signals, generating a first test response signal that indicates that the operation of the APS process of the first node is performed normally; a top priority local request selection unit selecting a top priority local request signal based on priorities of the first test response signal and at least one local request signal that indicates the status of the APS process of the first node; and an output signal determination unit determining an output signal to be transmitted to the second node based on priorities of the top priority local request signal and the filtered far end request signal.
