Said interface comparing unit is used for the normal information under more said detected port information and the relative set state, when comparative result is unanimity, gets the normal result of outgoing interface, otherwise gives the abnormal result of outgoing interface;
Said audio frequency transmitting element is used for when said state set unit FXO/FXS interface is set to off hook state; Send voice data and play to said digital switch through said interface, the voice data of said broadcast exchanges on one of FXS interface, FXO interface;
Said frequency spectrum comparing unit is used for more said voice data and the recorded message of the corresponding said voice data that the closed loop that is connected to form through FXS interface and FXO is passed back from two of said FXO interface, FXS interface; Said recorded message and broadcast information are carried out spectrum energy analysis, comparison, the tonequality result who obtains after obtaining relatively at last.
