Abstract
The special application of step-by-step dial switching equipment to the handling of short distance toll telephone traffic was introduced in Connecticut in 1929, and has been extended gradually until at present approximately 46,000 toll messages per day, comprising 70 per cent of the traffic between exchanges in this area, are dispatched over the 1,367 circuits of the dial switching network. The resulting. service improvements and savings in operating efforts are discussed in this paper, and a brief description of the transmission and equipment characteristics of the system is given.
