Abstract
A switching network has a group of incoming lines respectively connected to the terminal equipments of a plurality of subscriber stations. A group of outgoing lines are respectively connected to a plurality of trunk circuits. A plurality of crosspoints are formed between the incoming lines and the outgoing lines. Crosstalk is eliminated between mutually adjacent incoming lines or between mutually adjacent outgoing lines, by serially connecting a series circuit between the lines where crosstalk might otherwise occur. The serial circuit includes a phase inverter circuit and an impedance element having an impedance value which is sufficiently close to that of the impedance which is likely to cause crosstalk between these lines.
