Abstract

A system and method for monitoring connectivity in a cable system includes radio frequency identification (RFID) transponders on cable ends and RFID sensors at connection points. The RFID sensors are connected to a central monitoring system. Presence of a particular cable end at a particular connection point is detected and recorded by the central monitoring system.

Claims

1. A system for monitoring connections between plural mating positions made by a cable having a connector at each of two ends, comprising:

an electronic tag proximate each connector of the cable;

electronic tag readers proximate each of the plural mating positions to which each connector of the cable can connect; and

a monitor connected to the electronic tag reader, which controls the electronic tag reader, monitors presence of the electronic tag at a particular electronic tag reader, and determines between which of the plural mating positions the cable is connected.

2. The system of claim 1, used in a network, the monitor further comprising:

a processor executing a sequence of instructions defining;

creating a database mapping the network resulting from the connections made by the cable as determined by which of the plural mating positions are connected by the cable.

3. The system of claim 2, further comprising instructions executed by the processor of the monitor responsive to inputs specifying a desired change to the network, the instructions defining:

producing a work order indicating mating positions to which the cable is connected and the work order further indicating mating positions to which the cable should be connected upon execution of the work order.

4. The system of claim 3, further comprising instructions executed by the processor of the monitor responsive to changes in which mating positions are connected by the cable, the instructions defining:

producing an indication of an unauthorized change to the network.
