Abstract
Mejoras relacionadas con sistemas de centrales de comunicación caracterizadas por un equipo para insertar un supresor de eco en una conexión de central de comunicación que comprende medios para registrar si un canal que debe utilizarse en una conexión es de caracter dudoso o de segunda clase respecto al riesgo de eco, medios para registrar si otra parte de una conexión es de caracter dudoso o de segunda clase respecto al riesgo de eco, medios para confrontar si los referidos medios de registro están funcionando, y medios controlados por los referidos medios de confrontación para introducir un supresor de eco en una conexión.Improvements related to communication exchange systems characterized by equipment for inserting an echo suppressor in a communication exchange connection comprising means for registering whether a channel to be used in a connection is of a doubtful or second-class character with respect to risk of echo, means to register if another part of a connection is of doubtful character or of second class with respect to the risk of echo, means to check whether the said recording means are working, and means controlled by the said checking means to introduce a echo suppressor on a connection.
