Apparatuses and methods for analyzing at least one characteristic of a test signal coupled out from one of a plurality of cable lines by a coupling unit to determine whether that test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines. The determination of whether the test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines, may advantageously be used for operational or diagnostic purposes, e.g. to identify interconnections between ports in a network.

Signal processing apparatuses and methods for identifying cable connections between ports

An apparatus for identifying interconnections in a network. The apparatus comprises a plurality of transmitter coupling units, a plurality of receiver coupling units, and an interconnection identification means configured to identify interconnections between the transmitter coupling units and the receiver coupling units by cable lines in the network. In some embodiments, the interconnection identification means is configured to, if any one of the transmitter coupling units is coupled to the same cable line as a selected one of the receiver coupling units, identify the interconnection between the transmitter coupling unit and the selected receiver coupling unit according to by a binary tree search algorithm.

Apparatus for identifying interconnections and determining the physical state of cable lines in a network

Apparatuses and methods for coupling a signal to and from a twisted pair cable by non-contact coupling with twisted pairs in the twisted pair cable, such that the signal propagates along the cable between at least two of the twisted pairs. In particular, a coupling unit for coupling a voltage signal to and/or from such a cable, the coupling unit having a first electrode and a second electrode. The electrodes may be electrically isolated from a voltage signal generator and/or a voltage signal processor.

Apparatuses and methods for coupling a signal to and/or from a cable

A method of determining the state of a cable including at least one electrical conductor, uses a generated test signal and applies it to at least one conductor by a non-contact coupling transmitter. The resulting signal is propagated along the at least one conductor and a non-contact electrical coupling receiver picks up a reflected signal, and compares the reflected signal to expected state signal values for the cable to determine its current state.
