1. A method for detecting a single wire interruption of a line comprising two single wires, wherein such line is part of a vectoring group, comprising:
determining an overall capacitance measured between the two single wires of the line;
determining a line capacitance of the line;
determining a terminal capacitance of a terminal connected to the line; and
determining that a single wire interruption is present in at least one of the two single wires based on a difference between the overall capacitance and the line capacitance being less than the terminal capacitance.
