摘要： A synchronization message transmitting apparatus employs a synchronization message to synchronize a communication network. If an abnormality occurs in any part of the apparatus or on a clock in the apparatus, the apparatus detects the abnormality and prepares a synchronization message indicating that a frame to be transmitted must not be used for preparing a master clock. An opposite party that receives the frame with the synchronization message will not use the received frame for preparing a master clock.

摘要： A synchronization message detecting unit detects a synchronization message from a line signal received from a line terminating unit. A synchronization message processing unit controls whether or not to select a clock reference received from the line as an active reference according to a quality level represented by the synchronization message. In this case, when an installed state detecting unit has determined that the synchronization message detecting unit has not been installed, the synchronization message processing unit does not select a clock reference corresponding to the synchronization message detected by the synchronization message detecting unit determined as a non-installed unit as the active reference.

摘要： A method for a path trace check reducing a load on a computer, raising the speed of the check, and easily enabling an increase of nodes to be added. On a sender side, a first computer simply generates path trace data, adds a specific code CR to this, multiplexes this to the transmission data, then transmits the same to a transmission line. On a receiver side, a second computer simply generates an expected value of the path trace data, autonomously compares this expected value and the actual path trace data extracted from the received transmission data by using the specific code, and determines coincidence of the two.

摘要： A frequency synchronous circuit has a first selection unit, a first counter unit, a second counter unit, a storage/average unit, and a comparison unit. The first selection unit is used to select one sampling signal from a first sampling signal having a first sampling time and a second sampling signal having a second sampling time shorter than the first sampling time. The first counter unit is used to count a reference signal supplied from outside the frequency synchronous circuit during the sampling time of the selected one sampling signal, and the second counter unit is used to count a synchronous clock signal to be output from the frequency synchronous circuit during the sampling time of the selected one sampling signal. The storage/average unit, which is operatively connected to the first counter unit, is used to store and average an output signal of the first counter unit. The comparison unit, which is connected to the storage/average unit and the second counter unit, is used to compare an output signal from the storage/average unit with an output signal from the second counter unit, and the frequency synchronous circuit outputs the synchronous clock signal whose frequency is synchronized in accordance with an output signal of the comparison unit. Therefore, a transition period determined from a power ON state to a stable state can be reduced, and further, an original clock signal can be obtained and output by removing any noise components from a clock signal.

摘要： A frequency synchronous circuit has a first counter unit, a second counter unit, a storage/average unit, and a comparison unit. The first counter unit is used to count a reference signal supplied from outside the frequency synchronous circuit during a sampling time which is defined by a sampling signal, and the second counter unit is used to count a synchronous clock signal to be output from the frequency synchronous circuit during the sampling time of the sampling signal. The storage/average unit, which is operatively connected to the first counter unit, is used to store and average an output signal of the first counter unit. The comparison unit, which is connected to the storage/average unit and the second counter unit, is used to compare an output signal of the storage/average unit with an output signal of the second counter unit, and the frequency synchronous circuit outputs the synchronous clock signal whose frequency is synchronized in accordance with an output signal of the comparison unit. Therefore, an original clock signal can be obtained and output by removing noise components from a clock signal which may include the noise components.

摘要： In a path status monitoring method and device which can enhance or reduce a band more rapidly, for example, SONET frames FR serially connected over 32 frames to which frame Nos. FN (“0”-“31”)) are assigned are cyclically generated respectively for paths P0-P2 in a cycle TC (=64 ms). After output timing delays TD0-TD2 of the frames FR are shifted by an optimal delay interval D (=21 ms) between the paths P0-P2 based on the number of the paths “3”, the output timing delays TD1 and TD2 are restored by preliminarily obtained transmission delays for the paths P1 and P2 to the path P0. When the frames FR are transmitted through each of the paths P0-P2, statuses (path statuses MST) where a reception fault has occurred in each of the paths P0-P2 are collected to be stored in the frame whose frame No. FN=“0”.
