Thousands of improvements in central office equipment in 5 years An Advertisement of the American Telephone and Telegraph Company IN THE last five years there have been hundreds of im provements of major impor- ViO ,""" 4 4 tance in telephone central office equipment in the Bell System, and lesser improvements by the thousands. Improvements have been made in switchboard cable, in relays, in cords, in condensers, in selectors, and in the development of new and better materials for all kinds of equip ment used in the central offices. These improvements have not only helped to meet the steadily increasing complexity of telephone requirements. They also make possible the high-speed service which is eliminating delay from the personal contacts of people anywhere in the United States, whether they be separated by three floors of a building or three thousand miles of country. There is no standing still in the Bell System. Better and better tele phone service at the lowest cost is the goal. Present improvements con stantly going into effect are but the foundation for the greater service of the future.
