Design engineers now have available the results of many years of operating experience of submerged-repeater systems supplied from electronic, electromagnetic and rotary-machine power equipments. To meet the very high standards of reliability required for the transatlantic telephone system, a scheme has been evolved that is a combination of new developments and the best features of previous methods. Electronic-electromagnetic equipment forms the basis of an automatic no-break system requiring very little routine maintenance.
