Abstract

Perfeccionamientos en dispositivos de conmutación de protección para un sistema de conmutación de comunicaciones, que comprende; una red de conmutación; un grupo de unidades de interfase de líneas conectados a la red; un grupo correspondiente de líneas de comunicaciones conectadas a las unidades de interfase; y una pluralidad de memorias de segmentos de tiempo asociadas con las unidades de interfase de líneas para controlar la transferencia de datos a través de las unidades de interfase de líneas; caracterizados porque el dispositivo de conmutación de protección comprende; circuitos de detección de error para detectar defectos en las unidades de interfase de líneas y para generar señales de error indicativas de un defecto en una unidad de interfase identificable del grupo de unidades; una unidad de interfase accesoria conectada a todas las líneas de grupo de líneas; una memoria de segmentos de tiempo asociada con la unidad de interfase accesoria para controlar la transferencia de datos a través de la unidad de interfase accesoria; y circuitería que responde a las señales de error para transferir datos entre la unidad accesoria y una línea conectada a una unidad del grupo de unidades identificada por las señales de error y para transferir información desde una memoria de segmentos de tiempo asociada con la unidad de interfase identificada por las señales de error a la memoria de segmentos de tiempo asociada con la unidad de interfase de líneas accesoria.
