Abstract

Un dispositivo para realizar pruebas de continuidad en sistemas de telecomunicación, sobre conexiones a líneas analógicas a 2-hilos conectadas a una malla de conmutación múltiplex por división de tiempo a través de un híbrido, caracterizado porque existen un transmisor de frecuencia vocal (S) y un receptor de frecuencia vocal (E) que son conectables a un bus múltiplex por división de tiempo (ZS) por medio de un circuito de control (Stz) y porque el circuito de control conecta el transmisor (S) en la abertura de tiempo de receptor (tx), y el receptor (E) en la abertura de tiempo del transmisor (ty), de la línea a ser probada.
