Abstract

Mejoras en centrales telefónicas de larga distancia que comprenden circuitos internacionales de entrada, circuitos nacionales accesibles desde dichos circuitos internacionales de entrada, circuitos internacionales accesibles desde dichos circuitos internacionales de entrada, puestos de operador internacionales y medios discriminadores en dichos circuitos nacionales, pero no en dichos circuitos internacionales. Adaptados para responder a una señal que entre por un circuito internacional de entrada para llamar a un operador internacional.Improvements in long distance telephone exchanges that include international entry circuits, national circuits accessible from said international entry circuits, international circuits accessible from said international entry circuits, international operator posts and discriminatory means on said national circuits, but not on said international circuits. Adapted to respond to a signal that enters through an international incoming circuit to call an international operator.
