CIRCUIT ARRANGEMENT FOR TRANSMITTING SIGNALS IN TELECOMMUNICATIONS NETWORKS
The invention relates to a circuit arrangement for transmitting signals in telecommunications networks. Said circuit arrangement has a first connection and a second connection for a first or a second lead of a transmission line. The first connection is connected to the first input and the second connection is connected to the second input of a rectifier. The positive output and the negative output of the rectifier are linked via an adjustable resistor. A third connection for a third lead of the transmission line is connected to the positive output of the rectifier via the series connection of a switch and a first diode. Said third connection is also connected to the negative output of the rectifier via the series connection of the switch and a second diode.
