Methods for transferring digital data between remote subscribers and Range Communications Control Centers within NRD sites are reviewed and baseband data transmission techniques for this purpose are examined in detail. First, the factors which influence baseband data transmission in existing NRD intra-site cable pairs are discussed. Next, a test program, which was designed to measure the transmission characteristics and the error rate performance of some simple baseband data techniques over these cable pairs, is described and the results are presented, analyzed, and interxpreted. Finally, the elements which require special consideration in the design of efficient, cost effective baseband systems for intra-station data transmission are stressed and some implementation suggestions are presented.
