  • Abstract
    THE ESSENTIAL operating facilities placed at the disposal of toll operators for the switching and completion of long-distance calls have, in a general sense, remained substantially unchanged since the early days of toll switching. It is still common practice, in toll offices, to have toll lines and local subscribers´ trunks terminate in multiple jacks and lamp signals with associated cords and plugs to permit the operator to answer and extend calls between local stations and stations at distant toll centers. In addition, toll operators are still dependent on the assistance of inward and through operators for connecting within and through distant toll centers.
