Abstract
A dynamic and automatic method and apparatus for changing the bandwidth of a digital communication session is disclosed. The communication session uses a plurality of channels for transmitting digital data between a first location and a second location. The rate of data or non-data characters in the transmitting digital data stream is detected. A utilization parameter is calculated by dividing the non-data rate by the overall transmission data rate. The number of the plurality channels is changed to maintain the utilization parameter in response to changes in the data rate.
