Abstract :
Present switching plans which utilize automatic switching equipment in the telephone plant call for many changes in the layout of circuits and routing of traffic. Where yesterday traffic was handled in as direct a path as possible with a minimum of switching, today one or more different routings may be used to connect the same two telephones at different times.
