Total Network Data System: System Plan

The planning effort for traffic data collection and processing for what was to become the Total Network Data System (TNDS) began in the mid-1960s. This plan gradually evolved as the initial steps were taken to mechanize portions of the traffic data collection and data processing functions for the Bell Operating Companies and AT&T Long Lines. This paper is divided into two parts. The first part, Sections II and III, presents an architectural view of the Total Network Data System. * Bell L a b o r a t o r i e s . + American Bell.
