Abstract

A system having a plurality of tracing interface modules that attach to the patch panels of a telecommunications patching system in a telecommunications closet. On the patch panels in a telecommunications closet are located a plurality of connector ports that receive the terminated ends of patch cords. The tracing interface modules mount to the patch panels and provide a mechanical sensor that can detect when a patch cord connector has been added to, or removed from, a connector port within the telecommunications closet. Accordingly, by connecting a computer controller to the various mechanical sensors, the computer can monitor and log all changes to the patch cord interconnections in an automated fashion.

Claims

1. A patch cord tracing module assembly that is adapted to be affixed to the face of a patch panel having a plurality of connector ports aligned in a row in a telecommunications system, comprising:

a circuit board containing a plurality of mechanical switches thereon aligned in a row;

a support frame for supporting said circuit board, said support frame having a bottom edge and a plurality of hinged levers pivotally extending from said bottom edge, wherein each of said hinged levers engages and activates a corresponding one of said mechanical switches when biased toward that mechanical switch by a predetermined force.

2. The assembly according to claim 1, further including a graphics overlay affixed to said circuit board, wherein said graphics overlay contains a visual indicator that identifies different locations on said patch cord tracing module that correspond in position with said mechanical switches.

3. A telecommunications system having point-to-point tracing capabilities, comprising:

at least one rack structure;

a plurality of patch panels mounted to each said rack structure and having an outer face;

a plurality of connector ports disposed on each of said patch panels;

a plurality of patch cords for selectively interconnecting different pairs of connector ports;

tracing modules mounted to said outer face of said patch panels above said connector ports, wherein said tracing modules contain mechanical switches that detect the presence of a patch cord in each connector port.

4. The system according to claim 3, further including a controller on each said rack structure that is coupled to each of said mechanical switches in said tracing modules.

5. The system according to claim 3, wherein said tracing module contains:

a circuit board upon which said mechanical switches are mounted;

a support frame for supporting said circuit board, said support frame containing a plurality of hinged levers that correspond in position to said mechanical switches, wherein said hinged levers engage and activate said mechanical switches when contacted by a patch cord when that patch cord is inserted into one of said connector ports.

6. A method of detecting the presence of a patch cord connector in a connector port within a telecommunications closet, comprising the steps of;

providing a mechanical switch proximate each of the connector ports by positioning a mechanical switch at a point external to each of the connector ports, wherein each mechanical switch within a connector port is activated by the insertion of a patch cord connector into that connector port;

coupling each of said mechanical switches to a controller that monitors the switching status associated with each of said mechanical switches.

7. The method according to claim 6, wherein said step of providing a mechanical switch includes the step of attaching a tracing module in front of each connector port, wherein each said mechanical switch is contained within said tracing module.

8. The method according to claim 7, wherein said tracing module contains:

a circuit board upon which each said mechanical switch is mounted;

a support frame for supporting said circuit board, said support frame containing a plurality of hinged levers that correspond in position to each said mechanical switch, wherein a hinged lever engages and activates each of said mechanical switches when contacted by a patch cord when that patch cord is inserted into one of said connector ports.
