System and method for automatic addressing of devices in a dedicated telecommunications system
First Claim
1. A system for automatic addressing of devices in a telecommunications rack assembly, the system comprising:
- a patch panel including a plurality of connector ports;
a tracing interface module juxtaposed with said patch panel, said tracing interface module including a plurality of sensors, wherein ones of said sensors are established in a cooperative relationship with ones of said connector ports for detection of a connection at a port;
a plurality of light emitting diodes (LEDs) on said tracing interface module, ones thereof corresponding to ones of said plurality of sensors;
a plurality of tracing buttons, ones thereof corresponding to ones of said plurality of sensors;
a rack controler including a central processing unit (CPU) and a display;
wherein said tracing interface module and said rack controller are electrically interconnected.

Abstract
The present invention provides for automatic addressing of devices on a rack controller bus. As each tracing interface module in a rack is powered up, the device identifies its electronic serial number (ESN) to the rack controller via the rack controller bus. The ESN includes information identifying the type of module, and the number of ports on the module to the rack controller. The rack controller maps the module'"'"'s ESN to a unique address, which it sends back to the module. In subsequent communications, the module uses this address to identify itself to the rack controller, and the rack controller uses this address to track the location of patch connections to the module. If a module is replaced, the rack controller tracks the replacement using the same address assigned to the original module. Another embodiment of the invention provides for automatic addressing of rack controllers in a cross-connect field wherein a hardware implementation allows each rack controller to automatically determine its relative position on the cross-connect LAN and address itself accordingly. As new rack controllers are added, each rack controller reassigns its address, tracking the relative position of the other rack controllers in the cross-connect field and, hence, maintaining the integrity of its database.

9. The system of claim 8 wherein said unique module address is no more than two bytes in length.
-
10. The system of claim 8 wherein upon said module being replaced, said rack controller tracks the replacement module using said address assigned to said original module.
-
11. The system of claim 1 further including a plurality of telecommunication rack assemblies connected in a cross-connect field, each said rack assembly including at least one tracing interface module and at least one rack controller, wherein upon power-up of a rack controller:
-
said rack controller announces its presence and broadcasts its electronic serial number (ESN) to other rack controllers in the cross connect field; and
each said rack controller tracks patch connections between tracing interface modules on other racks using said rack controller addresses.
-
-
12. The system of claim 11 wherein upon a new rack controller being added, each rack controller then dynamically reassigns its address, and tracks the relative position of the other rack controllers in the cross connect field.
-
13. The system of claim 1 wherein said CPU is operable to line tracing programs.
-
14. The system of claim 1 wherein said CPU contains an access port that enables the CPU to be accessed by a remote computer.
-
15. The system of claim 1 wherein said rack controller manages and gathers data from the various tracing interface modules.
-
16. The system of claim 1 wherein upon a patch cord being placed into said connector, said sensor senses the connection of said patch cord, and said sensed connection is read to said CPU in said rack controller.
-
17. The system of claim 1 wherein said patch cord is removed and said sensor senses the disconnection of said patch cord, and is read to said CPU in said rack controller.
-
18. The system of claim 1 wherein said CPU maintains a log of all changes that have occurred with respect to the installation of patch cords into said connector ports.
-
19. The system of claim 1 wherein the endpoints of said patch cord can be traced by pressing said trace button that corresponds in position to a known end of the patch cord, and said CPU will review its log and determine where an opposite end of said patch cord is located and cause said LED to light on said tracing interface module where the opposite end of said patch cord is located.
