SIMULATED TESTING SYSTEM FOR ELECTRONIC EXCHANGE AND METHOD THEREFOR

PROBLEM TO BE SOLVED: To recognize the verification of a user network interface layer message by resolving the received user network interface layer message into constituting element units so as to output them to a magnetic disk. SOLUTION: An element name and an value obtained by an element value extracting means 142 are outputted to the message analysis result file 147 of the magnetic disk 111 by a message information output means 145 and outputted to CRT. A succeeding element judging means 143 judges the succeeding element by the element name and the element name which is defined from the element name in a message defining file 146. A speech path system simulating means 110 analyzes the user network interface layer message in a received call control signal and, after that, information by message kind within the extracted elements is given to a response message editing means 144. A response message kind is decided by the message defining file 146 here, the values of the respective elements in the defined response message are obtained and the values are edited as the response message.
