How do phone calls across the Atlantic Ocean?
Transatlantic telegraph cables were undersea cables running under the Atlantic Ocean for telegraph communications. Telegraphy is now an obsolete form of communication and the cables have long since been decommissioned, but telephone and data are still carried on other transatlantic telecommunications cables.
Is there an Internet cable across the ocean?

How did transatlantic phone calls work?
This system made use of two coaxial cables, one for each direction, and used analog FDM to carry 36 two-way voice circuits. With the availability of the cable system, transatlantic telephone traffic increased dramatically, from 1.7 million calls in 1955 to 3.7 million in 1960.
