SIMPLE EXCHANGE SYSTEM HAVING A VOICE DATA EXCHANGE FUNCTION WITH AN EXTERNAL EQUIPMENT AND A CONTROLLING METHOD THEREOF, ESPECIALLY RELATED TO TRANSFERRING VOICE MESSAGE DATA USED IN THE SIMPLE EXCHANGE SYSTEM TO AN EXTERNAL HIGH-CAPACITY EQUIPMENT TO STORE THE DATA IN THE EQUIPMENT

摘要

PURPOSE: A simple exchange system having a voice data exchange function with an external equipment and a controlling method thereof are provided to transceive VMS(Voice Mail System) data with an equipment of an external communication network, in order to transfer voice message data to the high-capacity external equipment, thereby remarkably increasing the expandibility of a voice message storage space of the system. CONSTITUTION: VMSs(5A-5N) compressively store voice message signals. A data type converter(6) converts voice data of the VMSs(5A-5N) into a universal data type from a specific data type, loads date information on the converted data, and transmits the converted data or carries out a reverse process. A VoIP board(10) processes the converted data in IP/MAC packet data, and transmits the processed packet data to an external device(9) or performs a reverse process. A main processor(11) controls a data conversion transmission function of the external device(9) or between the VMSs(5A-5N).
