Abstract
Perfeccionamientos en dispositivos de transferencia de llamadas para utilizarse en sistemas de comunicaciones, que tienen una pluralidad de estaciones cada una de las cuales con capacidad de comunicación con otras estaciones por enlaces de comunicación internos en el sistema, teniendo cada una de las estaciones una pluralidad de botones inestables que entran en acción para establecer características o conexiones de comunicación con la estación, caracterizados porque cada dispositivo de transferencia de llamadas comprende una red de conmutación que tienen una pluralidad de enlaces y un solo para de conductores de comunicación que se extienden hasta cada estación desde la red de conmutación, efectuándose la conexión bajo control de operaciones momentáneas de los botones, medios para designar uno de los botones en cada estación como botón de control de conferencia medios para disponer al menos dos de los botones en cada estación, actuando cada botón para activar conexiones a equipos del sistema por el par único de conductores medios que responden a la activación de uno u otro de los botones para conectar los conductores de comunicaciones desde la estación hasta el enlace siguiente disponible de los enlaces de la red, medios que comprenden el botón de control de conferencia y por lo menos uno de los botones controlados desde la primera de las estaciones para activar conexiones simultáneas de comunicación desde dos botones de estación activados al mismo enlace de la red de modo que los conductores de comunicación de un primer equipo del sistema que conecten al enlace de modo que los conductores de comunicación de un segundo equipo sel sistema se puedan conectar también al enlace para que se establezca una conferencia de tres usuarios entre la primera estación , el primer y el segundo quipos del sistema por el enlace, medios para permitir que la conferencia continua entre el primer y segundo equipos del sistema en el enlace cuando la primera estación se desasocia de la conferencia, y medios para permitir que la primera estación establezca una conexión desde cualquiera de los botones citados a un enlace desocupado siguiente aun cuando permanezca activada la conferencia entre el primer y segundo equipo del sistema
