On This Day in Telephone History December 21ST 1942 - Completion of Underground Transcontinental Telephone Cable. The all weather underground cable was not coaxial but quadded for carrier operation. The underground cable was completed and opened to regular service which was a WWII wartime feat. The final splice, bringing the cable into service occurred in Wendover, Nevada (on the Nevada/Utah border). This is the same location of the final splice of the first transcontinental cable which connected 130,000 telephone poles that joined more than 3,400 miles of telephone line. This splice connected the first telephone line from the East Coast to the West Coast of the United States of America.
