Method for increasing digital data throughput over telephone lines

Abstract

Transmission of digital data over existing telephone networks is limited by the data bit rate capacity of the telephone lines. This limitation is inherent in the nature of the existing communication lines e.g. copper wires and in the switching circuits that make the connections between telephone subscribers. Digital data may be transmitted over existing telephone lines but due to throughput limitation such transmission is exceedingly slow. A method is provided whereby a digital data file may be transmitted over a plurality of telephone lines simultaneously to increase the throughput and thus greatly increase the speed at which a given digital data file may be transmitted. The method does not require modification nor enhancement to the existing telephone network. The method consists of segregating the data file into smaller blocks of data, sequentially addressing such blocks and transmitting the blocks of data individually and concurrently over a plurality of telephone lines, with each successive block of data being sent over the next to be available telephone lines until all the blocks of data have been transmitted. At the receiving end the sequentially labeled blocks of data are reassembled to form a copy of the original digital data file.
