Abstract

Disclosed is a distribution unit which provides means for tracing patch connections. Each module is electrically connected to a shelf controller through a backplane. The shelf controllers are, in turn, coupled to a host computer. Pressing a button on one module lights an LED on that module and on the module which should be connected thereto based on the data base in the host computer.

Claims

1. A telecommunications distribution frame comprising:

a plurality of shelves;

a plurality of modules within each shelf for connecting a cable to jumper cables;

means comprising a backplane including busses for electrically connecting each module to a host computer which includes a data base of which modules should be connected together by a jumper cable;

means associated with a first module for directing a first signal to said host computer through said backplane to locate a second module to be connected thereto;

means associated with the first and second modules for receiving a second signal from the host through said backplane, and for visually indicating that the second signal has been received,

whereby the said modules are identified by such visual indications.

2. Apparatus according to claim 1 wherein the modules optically connect optical fibers from a cable to optical fiber jumper cables.

3. Apparatus according to claim 1 wherein the means for directing a signal comprises a push-button on a front surface of the module which is separate from the jumper cables.

4. Apparatus according to claim 1 wherein the means for visually indicating that the signal has been received from the host comprises a light emitting device on a front surface of the modules.

5. Apparatus according to claim 1 wherein the means for connecting each module to the host computer comprises controllers coupled to corresponding shelves of panels.

6. Apparatus according to claim 5 wherein the controllers coupled to each shelf are coupled to the host computer by means of a local area network buss.

7. A module for connecting a cable to a jumper cable comprising:

means for signaling a host computer coupled to the module through a backplane, which host includes information as to where the module should be connected; and

visual means for indicating that said signal has been sent to and received from the host computer through the backplane.

8. Apparatus according to claim 7 wherein the indicating means is a light emitting device.

9. Apparatus according to claim 7 wherein the means for signaling comprises a push-button on the front surface of the module which is separate from the jumper cable.

10. Apparatus according to claim 7 wherein the module is adapted for optically connecting fibers in the cable to optical fiber jumper cables.
