ATM TRANSMISSION METHOD WITH MUTE COMPRESSION CONTROL FUNCTION, SYSTEM AND TRANSMITTER/RECEIVER USING THEREOF |
摘要 |
<p>An ATM transmission system which transmits voice data in an asynchronous transfer mode (ATM). It implements compression of a mute section over a channel by detecting the mute section of a call and by physically suppressing its transmission over the channel as an ATM cell. A transmitting side detects the mute section (1), generates vocal/mute information (2), and generates a mute start cell (3) and a mute end cell. A receiving side generates a mute section at a fixed interval when receiving the mute start cell, and returns to a normal receiving mode of a speech spurt cell immediately when receiving the mute end cell. The suppression of the mute section makes it possible to reduce the occupied bandwidth, and to increase the channel efficiency. <IMAGE> <IMAGE></p> |
