Claim:
1. A method, comprising: in a cable connection, which comprises a first section comprising one or more wire pairs and having a first end that is potentially connected to a first endpoint, and which further comprises a second section comprising the one or more wire pairs and having a second end that is potentially connected to a second endpoint, applying a test signal to a single wire pair selected from among the wire pairs via one or more signal-injection impedance-components that are connected to the single wire pair at a mid-point between the first and second sections; sensing the test signal on the single wire pair via one or more signal-sensing impedance-components that are connected to the single wire pair at the mid-point between the first and second sections; and based on the sensed test signal, determining whether or not the first section is connected to the second section at the mid-point.
