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. |
