Abstract
A voice cell transmission method by which a VTOA architecture is employed and the transmission delay time can be minimized when transmitting the voice cell, and a system using the method are provided. Voice transmission method, in an ATM transmission system for transmitting a voice traffic, which is compressed, and is provided on a payload of a standard cell in a short cell format, comprising the steps of forming voice frames in every predetermined period of a talk-spurt of one voice channel, and providing the formed voice frames continuously on the payload of the standard cell. In a detailed example, a number of the voice frames of the one voice channel provided on the standard cell are dynamically varied according to a status of the network.

Voice transmissions method, in an ATM transmission system for transmitting voice traffic, which is compressed, and is provided on a payload of a standard cell in short cell formats, comprising the steps of:
- forming voice frames in predetermined periods as short cells each within a talkspurt from a rising time and a dropping time of one voice channel;
- and
- providing the formed voice frames continuously on the payload of the standard cell.
An ATM transmission system, for transmitting a voice traffic, which is compressed, and is provided on a payload of a standard cell in short cell formats, comprising:
- plural cell assembling and disassembling circuits, each corresponding to one of a plurality of voice channels for receiving a voice signal of one of a plurality of voice channels;
- and
- a cell transmission controller for controlling to transmit cells output from the plural cell assembling and disassembling circuits in a predetermined order,
- wherein each of the plural cell assembling and disassembling circuits include a voice frame controller, which forms voice frames in every predetermined period within a talk-spurt having a rising time and dropping time of one voice channel, and
- a cell assembling controller, which continuously provides the formed voice frames on the payload of the standard cell.
