Abstract: PURPOSE: A method for outputting contents of a database of an exchanger is provided to input a corresponding relation address and a tuple count value and read a parameter values corresponded to the corresponding address and a tuple count value in a DB and output the address, the value and the parameter values by using an input managing window in an ATM management interface(AMI). CONSTITUTION: An operator inputs a relation number at a relation input section in an input managing window by displaying the contents of a DB on an output managing window in an AMI, and inputs a tuple count value in a tuple count input section(201). The input managing window transmits the relation number and the tuple count value inputted by the operator to a DB process in an exchanger(202). The DB process receives the relation number and the tuple count value from the input managing window in an AMI, and searches a relation corresponded to the number by analyzing the relation number(203). The DB process increases the count in the tuple count value received from the input managing window after searching the corresponding relation(204). After the count value is increased, the DB process judges whether the increasing current count value is reached to the tuple count value(205). If the current count value is not reached to the tuple count value, a table in the DB reads a parameter value corresponded to the corresponding relation to the tuple count value(206). The DB process transmits the parameter value read from the table to the tuple count value on an output managing window in the AMI successively(207). If the current count value is reached to the tuple count value, the DB process transmits the parameter value read from the table in finally counted time to the output managing window in the AMI(208). The output managing window successively receives the corresponding parameter value corresponded to the relation from the DB process, and displays the received parameter value for making the operator confirm the value(209).
