<p>An ATM transmission system which transmits voice data in an asynchronous transfer mode (ATM), in which a silent section of a call is detected and the silent section is not physically sent as an ATM cell through a transmission line, realizing compression of the silent section on the transmission line. The sending side detects the silent section, generates voice/silence information, and generates a silence starting cell and a silence ending cell. The receiving side generates silent sections at regular time intervals upon receiving the silence starting cell and returns to its normal voice cell receiving state upon receiving the silence ending cell. Since the silent sections are not transmitted, the number of occupied bands is reduced on the transmission line and the efficiency of the transmission line can be improved.</p> |
