Abstract:
A frame having a payload portion supporting imbedded synchronous and asynchronous traffic for communication over a digital subscriber line having a prescribed data late, comprising:(a) a first payload group of U octets of uncoded payload for the synchronous traffic in the payload portion of the frame; (b) a second payload group of C octets of coded payload for the asynchronous traffic in the payload portion of the frame; (c) said first payload group is divided into a plurality of synchronous sections and said second payload group is divided into a plurality of asynchronous sections wherein the synchronous sections of the first payload group alternate with the asynchronous sections of the second payload group; (d) the values of U and C are respectively modifiable to accommodate changes in traffic load and data traffic rate within the bounds: 0&lE;U&lE;N; 0&lE;C&lE;N; where N=total length of the payload portion of the frame; and(e) the value of C is increased and the value of U is decreased without a change in traffic load in response to an improvement in signal quality over the digital subscriber line, if the improved signal quality enables an increase in the prescribed data rate.
