Abstract
This paper was written to present an operating engineer´s viewpoint of a particular nation-wide dialing installation from its conception to its realization. Providence, R. I., was chosen as subject of this presentation as this city appears to be typical of many others that are in service or proposed. Providence was chosen also because here is found utilization of a wide variety of the available instrumentalities and plans to incorporate probable future instrumentalities.
