Total Network Data System: System plan

The Total Network Data System (TNDS) is a coordinated family of operations systems that work together to mechanize telephone traffic data gathering and reporting. This paper describes the component parts of the TNDS, their functions, their interactions, and their inputs and outputs. The paper also presents the managerial view of TNDS: its product, its size, the number of people involved, how the overall project is organized and coordinated, and how the system evolves to meet the needs of a continually changing environment.
