Abstract
A system for dynamic allocation of voice and data channels in a time division multiplexed telecommunication system is disclosed. Multiple time division multiplexed lines are provided between a Teleco central office and a number of remote terminals. The time division multiplexing provides multiple channels on each of the multiple DSL lines so that multiple POTS devices can be connected to a single remote terminal. In addition, the remote terminal provides a high speed data port for connection to a data device such as a computer, a router, a bridge, a switch or other similar devices. The multiple TDM channels on each DSL line are allocated so that all of the channels are available for transmission of voice signals and all of the remaining open channels are available for the transmission of data signals. Open available channels are allocated for the transmission of data packets only during the duration of the transmission time of the data packet to minimize the delay in allocation of channels for the transmission of voice signals. The Teleco central office includes a central office terminal controller that is under the control of a CPU that routes voice signals to the central office s…
