Abstract
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.
Claims30
A monitor circuit for indicating whether a digital signal cross-connect bay has a cross-connect jack that cross-connects equipment being tested, the circuit comprising:
- a sensor having an input operatively coupled to a steady-state DC carrying wire wherein the sensor detects a change in current flowing in the wire and generates an output signal at its output upon detection of a change of current flowing;
- a comparator having an input operatively coupled to the output of the sensor wherein the comparator generates an output signal if the output of the sensor is above a predetermined level;
- and
- a filter coupled to a power supply that also supplies power to the cross-connect bay for powering the monitor circuit.
A monitor circuit for indicating whether a digital signal cross-connect bay has a cross-connect jack that cross-connects equipment being tested, the circuit comprising:
- a comparator receiving a signal output by a sensor that senses a change in current in a steady-state DC carrying wire;
- and
- a filter coupled to a power supply that also supplies power to the cross-connect bay for powering the monitor circuit.
A monitor circuit for indicating whether a digital signal cross-connect bay has a cross-connect jack that cross-connects equipment being tested, the circuit comprising:
- a sensor that senses a change in current in a power feed wire of the bay, the sensor not being electrically connected in series with the power feed wire;
- a comparator operatively coupled to an output of the sensor;
- and
- an indicator operatively coupled to an output of the comparator wherein the comparator sends a signal to the indicator if the sensor detects a current change in the power feed wire of the bay causing the indicator to generate an indication.
