1. An anomaly detection system, comprising: a telecommunication line having a plurality of wires including at least a first wire joined to a second wire, the telecommunication line having a time varying anomaly at a junction of the first wire and the second wire, the time varying anomaly causing a transmission characteristic of the telecommunication line to fluctuate at the junction; a transmitter coupled to the telecommunication line; and anomaly detection logic configured to detect the anomaly based on signals communicated across the telecommunication line, the anomaly detection logic further configured to indicate a location of the detected anomaly along the telecommunication line.
