A monitor circuit for indicating whether a digital cross-connect bay has a cross-connect jack that cross connects equipment being tested that includes a non-intrusive sensor for sensing current changes in a power feed line of the bay being monitored. The non-intrusive sensor is operatively coupled to a sensor device that generates a signal to activate an external sensor if a current change is detected by the sensor. The sensor device is powered from the same power supply as the bay it is monitoring.
