Abstract
A storage unit includes an alarm state/timer table, an alarm state table, an alarm state OR-representation table, an alarm state change OR-representation table, an alarm state latch circuit, and a statistical information memory. A collection unit extracts the identifier and data from a cell that passes through a switching unit. An update unit updates associated data in the storage unit. A readout unit reads the updated data and sends it to a call processing processor. An address generation section selectively generates the address for data needing to be updated. An adjustment section forces the readout unit to wait until a cell slot arrives in which no data is updated.
