Transatlantic telephone system by G. H. Davis
A step-by-step diagram demonstrating the new transatlantic telephone system between Britain and the United States in 1927.
The process involved the British caller asking for American Service, please after which the call would be put through the English transmitting station at Rugby. Here it is transferred by wireless and flung out to space. Crossing the Atlantic it reaches the receiving station at Houlton, Maine, USA and then by cable to New York. An operator would observe the needle of the voice-recording galvanometer and regulate it so that the sound was uniform and distinct. The minimum three-minute call to New York at the time cost 15.

EDITORS COMMENTS
This diagram by G. H. Davis, published in 1927 by Illustrated London News Ltd, illustrates the groundbreaking transatlantic telephone system connecting Britain and the United States. The process began with a British caller placing a request for American Service, initiating the call's journey through the English transmitting station at Rugby. The call was then transferred wirelessly and sent into space, traversing the Atlantic Ocean. Upon reaching the receiving station at Houlton, Maine, USA, the call was transmitted via cable to New York. An operator at the receiving end monitored the voice-recording galvanometer, ensuring the sound remained uniform and clear. The minimum three-minute call to New York during this era cost 15 shillings. This technological marvel revolutionized long-distance communication, bridging the Atlantic and bringing people closer together than ever before.
