Toll switching plan for Wisconsin

DEVELOPMENTS of telephone plant and technique have extended constantly the distance over which it is technically possible and commercially practicable to furnish toll telephone service. The result of this extension in the range of transmission has been to increase the number of possible commercial toll connections and to stimulate growth in toll service. In this paper, the toll switching plan for Wisconsin including some features of the transmission design requirements and the present and proposed toll cable network is outlined briefly. The relationship of the plan to that for handling countrywide toll connections also is touched upon.
