A history of Transatlantic Cables
IEEE Communications Magazine, 2008Co-Authors: Mischa Schwartz, Jeremiah HayesAbstract:Exactly 150 years ago, August 1858, the world witnessed a historic event in the history of telecommunications: the successful transmission of telegraph messages across the Atlantic Ocean. Although the Transatlantic Cable carrying these messages failed after a few weeks of operation, and it wasn't until 1866 that permanent Transatlantic telegraph Cable transmission became possible, the 1858 transmissions were heralded worldwide as a major achievement, introducing a new Age of Information. To commemorate this literally earth-shaking accomplishment 150 years ago, the History Column this month presents an article entitled ?A History of Transatlantic Cables? by Jerry Hayes of Concordia University, Canada, a member of the ComSoc History Committee. Interestingly, it took almost another 100 years until the first Transatlantic telephone Cable, TAT-1, was successfully launched. Jerry covers this epoch-making event in his article as well, in addition to the various undersea telephone Cables that followed in the years after. So we are actually commemorating two historic events in this column: the first successful transmission of telegraph data across the ocean, and the first successful Transatlantic Cable transmission of voice. We commend the article following to you.Special Notice: The ComSoc History Committee is sponsoring a special History Session at the forthcoming IEEE GLOBECOM 2008 in New Orleans. This session, the first of its kind, and coorganized by History Committee members Jacob Baal-Schem of Israel and Mischa Schwartz, will take place Tuesday, December 2, from 1:30-6 p.m. It will consist of three parts: a keynote address on the history of OFDM by Steve Weinstein, a past President of ComSoc and a pioneer in the field of OFDM; four reviewed papers covering a variety of topics on the history of communications; and a panel discussion on the topic "Who Invented Radio?" The panelists, a distinguished group of authorities and historians in the field, drawn from the Uni

Voices under the Atlantic [Scanning our past from London]
Proceedings of the IEEE, 2002Co-Authors: Lenore SymonsAbstract:Telegraph communication across the Atlantic began in 1866, when a Cable was successfully laid between Newfoundland and Valencia, Ireland. The first commercial voice link across the Atlantic was inaugurated in 1927 with a single radio telephone circuit. During the 1940s, however, the necessary equipment was gradually developed. The elements necessary for Transatlantic telephony by Cable included coaxial Cables with polythene (polyethelene, or polymerized ethylene) insulation. The Bell System approached the British Post Office to invite collaboration, together with the Canadian Overseas Telephone Corporation to lay a system across the Atlantic. In November 1953, they signed the Transatlantic Cable Construction and Maintenance Contract to complete the system by 1956.

The BT experience of implementing 140 Mbit/s 8-PSK carriers for Transatlantic Cable restoration purposes
1993Co-Authors: D.w. ProuseAbstract:For many years, the satellite communications fraternity has grappled with the problem of squeezing carriers with an information rate of 140 Mbit/s into a transponder bandwidth of 72 MHz, which has a practical transmission rate limit of around 60 MBaud (i.e. 120 Mbit/s when using the 4-phase PSK modulation technique). This paper describes the BT experience in implanting the solution agreed upon with AT&T and France Telecom for the restoration via satellite of failed Transatlantic Cable systems. The paper charts progress from the decision to use 8-phase Phase Shift Keying (PSK) with rate-5/6 Forward Error Correction (FEC) encoding through to successful operation, including details of system design, implementation, performance evaluation and operational experiences.

The Transatlantic Cable-an Irish perspective
Proceedings of the IEEE, 2002Co-Authors: Cornelia ConnollyAbstract:One of the papers presented at the IEEE History of Telecommunications Conference in Newfoundland last July looked at the first Transatlantic Cables from an Irish perspective. The author has studied the local impact of the Cable as a relatively poor and isolated community suddenly found itself at a hub in the worldwide telecommunications network. The paper describes the Valentia community, the Cable station staff, and the Cable stations at Valentia, Waterville, and Ballinskelligs.
