Here are some of the ways we handle your telephone calls today

A buried coaxial cable may carry as many as 9300 phone conversations at one time.

Radio relay systems can handle more than 17,000 simultaneous phone conversations.

Submarine cables whisk your words underseas as clearly as when you talk across town.

These developments will speed your telephone conversations tomorrow

A worldwide system, pioneered by Telstar® satellites, may speed your calls via space.

Electronic Switching will connect you faster, provide many useful new phone services.

Directly-dialed Collect and Person calls will speed to completion with Operator aid.

And all are planned to meet an expanding nation's need for service

As the population grows and households multiply and business machines devour greater mountains of data, the Bell System must constantly find and develop new communications techniques to stay ahead of new demands. We're working hard to do that today. And we can promise you finer, faster, more versatile services tomorrow.
