摘要： Provided are a data transceiver and method for performing equalization and pre-emphasis adaptive to the transmission characteristic of a transmitting part. The transceiver measures the signal attenuation characteristic of a transmission line of a receiving part using an input data signal input via the transmission line of the receiving part, decodes the distorted waveform of the input data signal, distorts the waveform of an output data signal beforehand using the measured signal attenuation characteristic of the transmission line of the receiving part, and transmits the output data signal via a transmission line of a transmitting part. Thus, when the output data signal is transmitted via the transmission line of the transmitting part, the waveform of the signal remains optimized.

摘要： Provided is an operational status testing apparatus and method for an Ethernet-based APS process. A test command signal which contains a command to perform an operational test for the APS process of a first node and a second test response signal that indicates that the operation of the APS process of a second node is performed normally, from among far end request signals that are received from the second node connected to own first node via an Ethernet network, are filtered. When the far end request signals are test command signals, a first test response signal that indicates that the operation of the APS process of the first node is performed normally is generated, and a top priority local request signal is selected 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 to be transmitted to the second node is determined based on priorities of the top priority local request signal and the filtered the far end request signal. The function for testing the operational status for the APS process defined in ITU-T recommendation G.8031 is embodied, and when an operational status test request is received from another node, the APS process can be tested effectively without having to perform a complicated diagnosis operation for the APS process.
