摘要： A method and system aggregate data on multiple physically separate lower-speed E1/J1 channels of a communications network to generate higher bandwidth. A high speed data stream is first divided into lower bandwidth channels and transmitted through the network. The data arrives with varying delays depending on the physical characteristics of the network. Low bandwidth channels are aggregated together into a high bandwidth channel by determining the different geographical delay parameters among the lower speed channels, adjusting the transmission delays by alignment circuitry, and then combining the lower speed signals into one high bandwidth channel for the user. The transmission delay adjustment consists in adding a pseudo-random noise pattern to each of the lower bandwidth channels, measuring the time difference among all the channels, and then adjusting the time differences in the received data stream so that the combination of the signals produces a coherent higher bandwidth data stream. Because of the enhanced delay compensation mechanism, there is virtually no distance limitation in the transmission of data and if one of the lower physical telecommunication lines becomes inoperative, bandwidth recovery is provided.
