   <abstract xml:lang="ru">
    <p>Показано, что покупка AT&amp;T в 1912 году у Ли де Фореста патентных прав на его аудион сделала реальностью осуществление проекта трансконтинентальной телефонной линии Нью-Йорк — Сан Франциско. Рассмотрены особенности строительства этой телефонной линии и возникшие при этом трудности. Уделено внимание разработке электрических схем и конструкций ламповых трансляторов, а также их установке на телефонной линии. Проанализированы принципы работы ламповых трансляторов типа 21 и 22. Приводятся результаты первого тестирования линии 29 июля 1914 года. Отмечен памятный день 25 января 1915 года — день торжественного запуска в коммерческую эксплуатацию трансконтинентальной телефонной линии за 25 дней дней до открытия Панамо-Тихоокеанской междуна-родной выставки в Сан Франциско.</p>

    <p>It is shown that AT&amp;T’s purchase of patent rights to his audion from Lee de Forest in 1912 made the New York – San Francisco transcontinental telephone line project a realty. The features of the construction of this telephone line and the difficulties that arose in this case are considered. Attention is paid to the development of electrical circuits and designs of tube repeaters, as well as their installation on a telephone line. The principles of operation of tube repeaters of type 21 and 22 are analyzed. The results of the first testing of the line on July 29, 1914 are given. A memorable day was marked on January 25, 1915 – the day of the solemn launch of the transcontinental telephone line into commercial operation 25 days before the opening of the Panama-Pacific International Exhibition in San Francisco.</p>
