Total Network Data System: Equipment Systems
N. D. Fulton, J. J. Galiardi, E. J. Pasternak, Sarah Schulman, Hartmut Voigt · Bell System Technical Journal · 1983
This article describes a set of five systems collectively called the Total Network Data System Equipment Systems, which support a number of network administration and engineering functions in the operating telephone companies. These systems are run by the operating telephone companies on large mainframe computers. In an average telephone company they support the management of the collection and distribution of over 50 million individual items of network data each week. They also provide reports to assist in the engineering and administration of No. 5 Crossbar switching offices, and the load balancing of all local switching systems. Initial development of these systems occurred in the early to mid-1970s. They are installed in all Bell System operating telephone companies and Bell Canada. Currently, on-line record base updates and inquiries and on-line viewing of report outputs are being developed.
