摘要： The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S11). The output message identifier MID is reserved (S12), and the tag information and output MID are assigned to the BOM (S13). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S31 and S32). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S41 and S42). Then, the output MID is released (S43).

摘要： A processing apparatus for measuring accumulated values of performance monitoring (PM) parameters concerning a reception signal received by a transmission device, which is capable of detecting upper layer failures in a more accurate, hardware-based way, without increasing the workload imposed on the system's firmware. PM parameters represent the statistics of events that meet prescribed criteria for defects and anomalies in the reception signal. The processing apparatus has a plurality of failure detection units to detect different kinds of failures in the reception signal and produce failure detection signals corresponding thereto. Those failure detection units include a first failure detection unit that detects a first kind of failure and a second failure detection unit that detects a second kind of failure. On the basis of the failure detection signals, a PM controller detects at least one kind of PM parameter, and a counter unit accumulates the detected PM parameter. A control signal generator produces a stop command signal that is activated while at least the second kind of failure is present. This stop command signal is supplied to the first failure detection unit to inhibit its operation and stop the detection of the first kind of failure.

摘要： The frame synchronizing circuit establishes frame synchronization by detecting a sync pattern laid in an incoming frame. The frame synchronization circuit comprises a first frame synchronizing unit and a second frame synchronizing unit. The first and second synchronizing units synchronize with a first pattern, a second pattern at a first position and a second position, respectively. Thereafter, when the first position used for the synchronization by the first frame synchronizing unit is found to be in error, the first frame synchronizing unit synchronizes with the second pattern at the second position used by the second frame synchronization unit.
