Jay Mahoney, J. J. Mansell, R. C. Matlack · Bell System Technical Journal · 1975
The utilitarian aspect of the Digital Data System is discussed with emphasis on performance objectives that will be important when data communications is inserted into a system of data processing. Objectives for the dependability and quality of data communications are quantified and evaluated in terms of their impact on data processing. Characteristics of the several types of channels available are described in detail along with operational features of particular importance at the interface between data communication and data processing.
