New York, American Telephone and Telegraph Company, 1957. 8vo. Original full green cloth, bound with the original blue wrappers. Volume 36, 1957 of "The Bell System Technical Journal". Library stamp to pasted down front free end-paper. Minor bumping to extremities. A nice and clean copy. [Entire issue:] 20, 1513 pp. First edition of the first technical description of the TAT-1, the first submarine transatlantic telephone cable system. The 2,240-mile cable was laid by the cableship Monarch and ran from Gallanach Bay, near Oban in Argyll, to Clarenville, Canada. The initial capacity was 36 calls at a time at a price per call of $12 for the first three minutes. Since trans-Atlantic service opened in 1927, calls had traveled across the ocean via radio waves. But cables provide much higher signal quality, avoid atmospheric interference and offer greater capacity and security."The papers that follow describe the design, manufacture and installation of the first transatlantic telephone cable system with all its component parts, including the connection microwave radio-relay system in Nova Scotia." (From the introduction to the present papers)."Years of development led up to 1956 when the first transatlantic telephone cable system started carrying calls" this is an interesting story in itself. Two coaxial cables about 20 miles apart carried 36 two-way circuits. Nearly 50 sophisticated repeaters were spaced from 10 to 40 miles along the way. Each vacuum tube repeater contained 5,000 parts and cost almost $100,000." (Petruzzellis, Thomas. Telephone Projects for the Evil Genius, 2008, p. 4). The electronic repeaters, the devices that held together the many separate cables, were designed by the Bell Telephone Laboratories. In terms of reliable operation, the most critical component of the system was the repeater. These devices, spaced at intervals of 37.5 nautical miles along the cable, compensated for loss. The repeaters were of a unique flexible design, which allowed them to be handled in the same manner as cable.TAT-1 carried the Moscow-Washington hotline between the American and Soviet heads of state.Other papers of interest contained in the present volume:1.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! The transatlantic telegraph cable was the first cable used for telegraph communications laid across the floor of the Atlantic Ocean. It crossed from the Telegraph Field, Foilhommerum Bay, Valentia Island, in western Ireland to Heart's Content in eastern Newfoundland. The transatlantic cable bridged North America and Europe, and expedited communication between the two. Whereas it would normally take at least ten days to deliver a message by ship, it now took a matter of minutes by telegraph.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Please note that the content of this book primarily consists of articlesavailable from Wikipedia or other free sources online. A cable layer orcable ship is a deep-sea vessel designed and used to lay underwatercables for telecommunications, electricity, and such. Cable ships aredistinguished by large cable sheaves for guiding cable over bow or sternor both. Bow sheaves, some very large, were characteristic of all cableships. Newer ships are tending toward pure stern layers with sternsheaves only as seen in the photo of the Cable Innovator at the Port ofAstoria on this page. The names of cable ships are often preceded by'C.S.' as in CS Long Lines. The first transatlantic telegraph cable waslaid by cable layers from 1857-1858. It briefly enabledtelecommunication between Europe and North America before misuseresulted in failure of the line. In 1866 the Great Eastern successfullylaid two transatlantic cables, securing future communication between thecontinents.…
