Annuaire Officiel des Abonnés aux Réseaux Téléphoniques des Départements (Seine, Seine-et-Marne et Seine-et-Oise exceptés). Année 1909 [ Annuaire Officiel des Abonnés au Téléphone ]
Précédé d'Instructions pour l'usage du Téléphone et des Conditions Générales d'abonnement, 1 vol. in-4 reliure pleine toile éditeur, 1909, 999-103 pp.
Vraie mine d'information, cet annuaire téléphonique des temps héroïques s'ouvre sur 3 pages d'instructions sur "l'usage du téléphone" : "avant de décrocher les récepteurs, tourner rapidement deux ou trois fois la manivelle de l'appareil magnétique". Etat très satisfaisant (couv. fort. frottée, bon état intérieur). Faisant suite à l'annuaire des particuliers, on trouve en fin d'ouvrage un annuaire des professionnels (à la mention "Librairie" on découvre un encart de la Librairie Dorbon qui achète des bibliothèques "au maximum de leur valeur").
Le Progrès enchaîné. Téléphone - Logement.
1 vol. in-12 reliure demi-basane verte, dos à 4 nerfs orné, Calmann-Lévy, Paris, 1966, 276 pp.
Bon exemplaire bien relié. Polytechnicien et ingénieur général des PTT, Henri Jannès met alors en garde sur le grand retard que la France avait pris en matière de télécommunication, et insiste sur le défaut de productivité. Il s'intéresse ensuite aux deux autres secteurs en crise : la construction et la construction navale.

Transatlantic Communications. TAT-1. - [FIRST DESCRIPTION OF THE FIRST SUBMARINE TRANSATLANTIC TELEPHONE CABLE SYSTEM, TAT-1]
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.
