Abstract
It is suggested to detect a single wire interruption (SWI) of a line comprising two wires, wherein such line is part of a vectoring group, comprising (i) determining a capacitance between the single wires of the line; and (ii) determining whether a single wire interruption is present based on the determined capacitance.
Claims14
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.
The method according to any of the preceding claims, which is run on a central unit, in particular a distribution point unit (DPU), a digital subscriber line access multiplexer (DSLAM), a multi service access node (MSAN) or a media converter.
A central communication device comprising a processing unit that is arranged to conduct the following steps:
- determining an overall capacitance between two single wires of a line, wherein such line is part of a vectoring group;
- 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.
A non-transitory computer readable medium storing code portions that cause a digital processing device to perform operations comprising:
- determining an overall capacitance between two single wires of a line, wherein such line is part of a vectoring group;
- 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.
