The base telephone cable plant on each base represents a substantial investment it was constructed to accommodate the base telephone system and a limited amount of low-speed data. Recently, however, more demanding requirements for the transmission of high-speed data are being imposed on this cable plant in increasing quantities. In order to accommodate these more demanding requirements, we must make more efficient use of the existing cable plant i.e., utilize it for wider bandwidths than the nominal 4KHz voice channel. As a first step, this report reviews the engineering fundamentals involved in the transmission of information over base wire paths. It reviews basic transmission fundamentals, transmission of voice information, transmission of digital data, and multiplexing and concentration techniques. Author
