A wide-band communication network and a method for tracing disturbances therein.

摘要

A method and device for tracing disturbances in a wide-band communication network comprising a control unit and field terminals for information flows in two directions, whereby in accordance with a programme the modems of the field terminals can be set to another frequency by remote control and whereby the network can be arranged so as to switch, in batches as well as individually, one or more field terminals and/or an intermediate terminal with all field terminals connected thereto and the control unit to another carrier frequency. <IMAGE>
