Abstract : The purpose of the report is to provide the basic information required to do preliminary systems engineering in transmission methods, and to make valid cost estimates of proposed system approaches. Emphasis is placed on the compilation and description of basic communication techniques that are potentially useful for the electronic transmission of mail, in both analog and digital form; presentation of information on terminal and transmission subsystems that will give an overview of potentially useful technologies; demonstration of practical transmission system design approaches, for use in preliminary appraisals of different transmission media and methods; and provision of rational basis for estimating the recurring and nonrecurring costs of transmission systems, so that trade-off studies can be made to assist in the choice of methods to be used.
