Abstract
This paper outlines a comprehensive plan for improved switching of long haul toll telephone traffic in the United States and eastern Canada. A brief discussion is given of the methods of designing the toll plant to give adequate transmission efficiency for all connections established in accordance with this plan, including a new method of providing amplification at intermediate switching points replacing the cord circuit repeater method.Keywords
