Method and apparatus for transmitting compressed packetized voice over ATM

摘要

A system transmits compressed voice packets over ATM. The system receives a plurality of voice data units and an encoding rule for each voice data unit. A packet is formed from the received data units. The packet includes a header. The header includes the amount of data units in the packet, and the encoding rule for each packet. The packet is then placed in an ATM cell which is transmitted on an ATM virtual channel. The ATM cell includes at most one packet.
