ABSTRACT:
Electric network for use in a subscriber's loop, comprising at least two connecting terminals for supplying thereto a current flowing in the subscriber's loop, the network comprising the series arrangement of a capacitive element and a switching device and a threshold device coupled to the connecting terminals and the switching device for either coupling or not coupling, depending on the polarity and the value of said current, said capacitive element to the terminals of the network. This results in a network whose pattern of behavior is optimum for the various signals which are exchanged in the loop.
